Kutaja – The Best Anti-Dysenteric Drug

Introduction

Kutaja is botanically known as Holarrhena antidysentrica Wall. is found in various tropical and subtropical regions of Africa and Asia. Kutaja is a lactiferous small shrub or small tree. Kutaja is specifically found in the Himalayan ranges of India. Kutaja has traditional value in India like in Orissa state people offer the leaves of Kutaja with rice to each other during their famous festival Nabanna. In districts of Uttara Pradesh like Mirzapura, and Varanasi it is used for various gastrointestinal problems. The United state is the largest buyer of Kutaja in the year 2014- 2016 from India. In Ayurvedic classical texts, Kutaja is mentioned in various places. Acharya Charaka has quoted Kutaja in Kalpa Sthana under Vamana Dravya. A whole Chapter is mentioned for Kutaja and 18 formulations of Kutaja are mentioned in that chapter. Acharya Charaka mentioned two types of Kutaja Pun (male) and Stri (female) Kutaja. Along with this Kutaja is used in various formulations in Ayurveda like Kutaja Arishta, and Kutajaghna Vati. It is classically considered the best drug for curing Parvahika, Atisara, Arsha, Kustha, Trishna, etc. A recent study revealed that Kutaja consists of various active principles like conessidine, kurchine, holadysamine, holadysine, kurchicine, etc. due to which it exhibits various pharmacological activities like anti-hyperlipidemic, anti-hyperglycemic, anti-cancer, antioxidant activity, alexipharmic activity, analgesic activities, etc.

Kutaja’s Description in Brihtrayi

Two kinds of Kutaja, male and female have been recognized and the synonyms mentioned here include those for both the source plants and their seeds (Phala or Bija). Dalhana has differentiated between the two kinds as follows. The male variety is that which has larger fruits, white flowers, and smooth leaves and the female variety has small fruit stalks, and the flowers are blackish-brownish. Holarrhena anti- dysenterica Wall., and Wrightia tinctoria R. Br. (or W. tomentosa Roem. & Schult.) are taken to be the two kinds referred to above.

The bark of the former and the seeds of both are generally collected for the market. The seeds known as Indrayava from the two are differentiated as bitter (Kadava) Indrayava and sweet (Mitha) Indrayava. Based on the general appearance of foliage etc. of the species they may also be called black (Krishna) and white (Sveta) varieties. On a comparison of the shape of the fruits of W. tomentosa (two follicles subcylindrical and connate throughout), W. tinctoria (two follicles cohering at their tips only), and Anti- dysenterica (two follicles distinct), the first two species may also be called male and female varieties of Sveta Kutaja.

Historical Background of Kutaja

In Manduki Siksha Kutaja is described as a toothbrush (Ma. Sc. 4/ 2). Charaka quoted Kutaja tvak as the best Sangrahika Dravaya (C. S. Su. 25). Bhavamisra mentioned Kutajabija (Indrayava) under Haritakyadi varga and Kutaja is described as Usna Virya while Indrayava is Sita Virya. Kutaja is the drug of choice for bleeding piles (Ardra Arsas).

Brhat Trayi has quoted Kutaja among the Vamana Dravyas. Caraka enumerated 18 yogas with Vatsaka in Kalpa Sthana (C. S. Ka. 5). In this context he described male and female varieties of Kutaja. According to him the plant with white flowers, smooth/ glabrous leaves, and big fruits will be male Kutaja while the plant with reddish flowers, smaller fruit, and grayish-black bark is female Kutaja. However, Cakrapani did not attribute any dissimilarity in their therapeutic utility. He quoted that both varieties shall be used in the same way. Dalhana described the plant with big fruits, white flowers, and glabrous/ smooth leaves as Pum Kutaja (male) and the plant with small fruit stalks and blackish-red colored flowers as Stri Kutuja (female). Siva Dutta also described Kutaja stating that Kutaja leaves are long, and possess white flowers and fruits are follicles. Some consider the male variety as Sita (white) Kutaja and the female variety as Asita (black) Kutaja.

Thakurji stated that- On a comparison of the shape of the fruits of Wrightia tomentose (two follicles sub-cylindrical and connate throughout) and W. tinctoria (two follicles distinct), the first two species also called male and female varieties of Sveta Kutaja.

V. Sharmaji believes that W. tomentosa may be the female Kutaja since its flowers are reddish-tinged. However, many scholars have correlated H. antidysenterica and W. tinctoria as male (white) and female (black) varieties of Kutaja. This view has an opinion that W. tomentosa is the original Kutaja since Bhanoji Dixit (commentator on Amarakosa) described Indrayava as the fruit of Kutaja. “Indra Sangksya Vrikshshya Yavam Indrayavam Kutaja Phalam. Even Vaidya Bapalal’s view provides further support. Yavakaar Beej Tvaat Yavam Indrasangksya Vrikshsya Yavam Kutaj Phalam| Phalani Indra Yavastsya Beejm Bhdra Yavstttha. From the above descriptions, it is apparent that the fruit and seed both resemble Yava in shape. Hence Indra Yava and Bhadra Yava are named respectively for fruits and seeds. The fruits of W. tomentosa which are connate throughout give the appearance of ‘Yava’ i.e., Indra yava, and its seeds are Bhadrayava. It is also important to note that the chemical constituents of even H. antidysenterica and W. tinctoria are entirely different. But in vogue, both are used as substitutes for each other. It is noticed that the former is used in diarrhoeal disorders while the latter is used in psoriasis (777 oil).

Varieties of Kutaja

The plant source of the drug Kutaja is commonly identified and known as Holarrhena antidysenterica (Linn.) Wall. ex G. Don. Further, there are two kinds of Kutaja viz. Sita or Tikta Kutaja (white or bitter) which is Holarrhena anti- dysenterica (Linn.) Wall. ex G. Don.; and Asita or Madhura Kutaja (black or sweat) which is identified as Wrightia tinctoria R.Br. and also Wrightia tomentosa Roem. Schult., both belonging to the family Apocynacee. Classically there are other two varieties of Kutaja viz. Strikutaja and Punkutaja.

As per modern classification, there are two varieties white and black varieties of Kutaja. The difference between both is mentioned below:

Variety Black (Madhur Kutaja)White (Tikat Kutaj)

In vitro cytotoxic activity of leaves extracts of Holarrhena antidysenterica against some human cancer cell lines. Indian Journal of Biochemistry & Biophysics. 51. 46-51. In vitro, the cytotoxic potential of extracts (95% and 50% ethanolic extract and hot water extract at a concentration of 100 microg/ml) from leaves of Holarrhena antidysenterica was evaluated against fourteen human cancer cell lines- A- 549, COLO- 205, DU- 145, HeLa, HEP- 2, IMR- 32, KB, MCF- 7, NCI- H23, OVCAR- 5, SiHa, SK- N- MC, SW- 620 and ZR- 75- 1 from nine different tissues (breast, colon, cervix, CNS, lung, liver, oral, ovary and prostate) using SRB assay. The 95% ethanolic extract displayed a maximum anti-proliferative effect in the range of 73- 92% against eight human cancer cell lines, while 50% ethanolic extract showed cytotoxic activity in the range of 70- 94% against seven human cancer cell lines. However, the hot water extract did not show any activity. Among the fractions of 95% and 50% ethanolic extract, significant cytotoxic activity was found in the chloroform soluble fraction of 95% ethanolic extract at 100 microg/ml; it inhibited the growth in the range of 71- 99% of seven human cancer cell lines from five different tissues viz., OVCAR- 5 (ovary), HT- 29 (colon), SK- N- MC (neuroblastoma), HEP- 2 (liver), COLO- 205 (colon), NIH- OVCAR- 3 (ovary) and A- 549 (lung). The cytotoxic activity of chloroform soluble fraction was found to be higher than 5- fluorouracil, adriamycin, mitomycin-c, and paclitaxel (anticancer drugs used as positive controls). Further in vivo studies and identification of active components from the chloroform fraction and their exact mechanism of action could be useful in designing new anticancer therapeutic agents.

Efficacy of an aqueous extract of seed of Holarrhena antidysenterica for the management of diabetes in the experimental model rat: A correlative study with antihyperlipidemic activity. International Journal of Applied Research in Natural Products. 2. The present study reports the effects of an aqueous extract of the seed of Holarrhena antidysenterica for the management of streptozotocin (STZ) induced diabetes in rats. For the management of the carbohydrate metabolism in diabetes by the said extract, the activities of carbohydrate metabolic enzymes like glucose-6-phosphatase, glucose-6-phosphate dehydrogenase, and hexokinase in the liver along with quantification of glycogen in liver and skeletal muscle were measured, and noted a significant recovery in respect to the diabetic control group. As hyperlipidemia is one of the disorders of diabetes so, we have also assessed the serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDLc), very low-density lipoprotein cholesterol (VLDLc), and high-density lipoprotein cholesterol (HDLc). The said aqueous extract also resulted in a significant recovery in the levels of the abovementioned biosensors of lipid profile when treated in experimentally induced diabetic rats. The extract has no toxic effect in general which has been focused on here by the monitoring of GOT and GPT activities in the liver and kidney. The results of this study enlightened that the aqueous extract of said plant part has both antidiabetic and anti-hyperlipidemic activities.

Background: Holarrhena antidysenterica L. traditionally treats amoebic dysentery, diarrhea, asthma, bronchopneumonia, malaria, and some other disorders. Aim: The current study was designed to explore the effects and possible mechanisms of Holarrhena antidysenterica on paracetamol-induced hepatic damage in a rat model. Materials and methods: Hepatic damage was induced in male Wistar rats with PCM (2g kg- 1) administration for 4 weeks. A liver histopathological study was performed, and the liver function was performed by determining the (SGPT) Serum glutamate pyruvate transaminase, (SGOT) Serum glutamic oxaloacetic transaminase, Alkaline phosphatase (ALP) and Total bilirubin (TB) for evaluating the effect of HAE on hepatic damage. The possible mechanisms were investigated by measuring hepatic collagen metabolism and oxidative stress level. Findings: HA extract care significantly inhibited the loss of liver weight induced by PCM. Then the HAE improved the liver function of rats as recorded by decreased serum enzymatic activities of SGPT, SGOT ALP, and TB (p< 0.05, p< 0.01). Histopathological results indicated that HAE alleviated liver damage and reduced the formation of fibrous septa. Moreover, HAE significantly decreased liver Hydroxyproline (Hyp) content. It also decreased liver Malondialdehyde concentration, and increased activities of liver superoxide dismutase, catalase, and glutathione peroxidase. The hematological Parameter induced by HAE is normally compared with the control. The standardized extract HPTLC investigation uncovered the presence of some critical phenolic compounds. Conclusion: This examination demonstrated that Holarrhena antidysenterica could be taken as a decent common wellspring of the hepatoprotective agent.

Pharmacologyonline. 3. 663-669. Wrightia tinctoria (Roxb.) R.Br. (WT) has been reported to exhibit several therapeutic uses such as astringent, stomachic, febrifuge, skin diseases, and tonic in India. The objective of the present study was to investigate the immunomodulatory activity of the bark extracts of WT using delayed type hypersensitivity reaction and carbon clearance assay. Powdered dried barks of WT were extracted with petroleum ether 60 – 80°C (PEWT), alcohol (ALWT), and aqueous alcohol (AQWT) (60 % water + 40 % ethanol) successively. PEWT and ALWT extracts (200, 400 mg/ kg, p. o) produced a significant increase in delayed-type hypersensitivity in response to sheep red blood cells (SRBC). PEWT showed better activity than ALWT in delayed-type hypersensitivity response. ALWT (200 and 400 mg/ kg, p. o) in a dose-dependent manner has shown a significant increase in phagocytic activity. The above results reveal that ALWT possesses immunostimulant activity in carbon clearance assay whereas PEWT and ALWT showed immunomodulatory activity in the delayed-type hypersensitivity model.

The present study was conducted to evaluate the hepatoprotective activity of phytoconstituents of methanolic extract of leaves of Wrightia tinctoria against D- galactosamine-induced liver damage in albino rats. The phytoconstituents (100 mg/kg) were administered orally to the animals with hepatotoxicity-induced D-galactosamine (400 mg/kg for two days). Silymarin (50 mg/ kg) was given as a standard hepatoprotective drug. All the test drugs were administered orally in the suspension form to the animals. The combination of silymarin and methanolic extract of Wrightia tinctoria leaves was also given to animals to compare with individual groups as well as toxicant groups. The combination of silymarin and methanolic extract of Wrightia tinctoria leaves was effective in protecting the liver against the injury induced by D- galactosamine in rats. This was evident from a significant reduction in serum enzyme alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin. These biochemical observations were also supplemented by Histopathological observations of livers sections. It was concluded from the results that the combination of silymarin and methanolic extract of Wrightia tinctoria leaves reduces the hepatoprotective activity against D-galactosamine-induced hepatotoxicity in rats.

The development of anthelmintic resistance and the high cost of conventional anthelmintic drugs led to the evaluation of medicinal plants as an alternative source of anthelmintics. The present study aimed to determine the anthelmintic activity of crude petroleum ether and chloroform extracts of leaves of Wrightia tinctoria using Pheretima Posthuma. Three concentrations (2.5, 5.0, 7.5 mg/ ml) of each extract were studied in the activity, which involved the determination of the time of paralysis and time of death of the worms. Piperazine citrate is used as a standard reference and normal saline as a control. The present study proves the potential usefulness of leaves of Wrightia tinctoria as a comparable anthelmintic agent.

Pharmacology online. 3. 294- 307. Ethanol bark and leaf extract of Wrightia tomentosa have been shown to exhibit anti-allodynic activity in Swiss albino mice. This study aimed to evaluate the comparative anti-allodynic effects of both the leaf and bark extract of the plant along with an acute oral toxicity study. Acute toxicity studies were carried out by using the Organization of Economic Co-operation and Development (OECD) guidelines 423, using a minimum number of male Wistar rats with defined doses (5, 50, 300, 2000 mg/ kg body weight) of extracts. The extracts treated animals did not show any mortality or observable signs of toxicity. From the toxicity studies, 1/ 5th of the dose was selected as the maximum dose for testing of anti-allodynic activity. The comparative anti-allodynic activity of ethanolic leaf and bark extracts was determined, with six groups of six albino mice each by tail immersion method. After the administration of test drugs in two different doses, the reaction time was measured at 0, 30, 60, 120, and 180 minutes. The highest reaction time was considered as a maximum anti-allodynic effect, which was exhibited by the bark extract (400 mg/ kg) after 120 minutes of administration with a value of 14.67 ± 4.17 seconds in comparison with standard drug aspirin (8.33 ± 1.72). The current studies generally focus on induced pain in animal models that are designed to evaluate anti-allodynic effects for humans shortly.

  • To evaluate the anti-cancer activities of the ethanolic extract of W. tomentosa and identified constituent active molecule(s) against breast cancer.
  • Powdered leaves of W. tomentosa were extracted with ethanol. The ethanolic extract, subsequent hexane fractions, and fraction F- 4 of W. tomentosa was tested for its anti-proliferative and pro-apoptotic effects in breast cancer cells MCF- 7 and MDA – MB- 231.
  • The ethanolic extract, subsequent hexane fractions, and fraction F- 4 of W. tomentosa inhibited the proliferation of human breast cancer cell lines, MCF- 7 and MDA- MB- 231. The fraction F- 4 obtained from hexane fraction inhibited proliferation of MCF- 7 and MDA- MB- 231 cells in a concentration and time-dependent manner with IC₅₀ of 50 μg/ ml and 30 μg/ ml for 24 h, 28 μg/ ml, and 22 μg/ ml for 48 h and 25 μg/ ml and 20 μg/ ml for 72 h respectively. The fraction F- 4 induced G1 cell cycle arrest, reactive oxygen species (ROS) generation, loss of mitochondrial membrane potential, and subsequent apoptosis. Apoptosis is indicated in terms of increased Bax/ Bcl- 2 ratios, enhanced Annexin-V positivity, caspase 8 activations, and DNA fragmentation. The active molecule isolated from fraction F- 4, oleanolic acid, and urosolic acid inhibited cell proliferation of MCF- 7 and MDA- MB- 231 cells at IC₅₀ value of 7.5 μM and 7.0 μM respectively, whereas there is devoid of significant cell inhibiting activity in non-cancer originated cells, HEK- 293. In both MCF- 7 and MDA- MB-231, oleanolic acid, and ursolic acid-induced cell cycle arrest and apoptosis as indicated by the significant increase in Annexin-V positive apoptotic cell counts. Our results suggest that W. tomentosa extracts have significant anti-cancer activity against breast cancer cells due to the induction of the apoptosis pathway. Olenolic and ursolic acids are important constituent molecules in the extract responsible for the anti-cancer activity of W. tomentosa.
  • Nagarajan, Kandasamy & Mazumder, Avijit & Ghosh, L.K. (2008). In vitro antioxidant activity of alcoholic extracts of Wrightia tomentosa. Pharmacologyonline. 1. 196- 203. The objective of the present investigation is to assess the most potent antioxidant alcoholic extract from the leaf & bark of Wrightia tomentosa. The invitro-methods used to-predict the antioxidant effect was DPPH radical scavenging assay, reducing power ability, Phospho molybdate method & the estimation of total phenolic and flavonoid contents using pyrocatechol & quercetin as standards. The % scavenging activity at different concentrations was determined and the IC 50 value of the extracts was compared with that of standard, ascorbic acid. The ethanolic bark extract gave an IC 50 value of 75.0 μg/ml when compared with leaf extract (IC 50 = 135.1 μg/ml). The reducing power was investigated by Fe3+ – Fe2+ transformation in the presence of extracts tested using Butylated hydroxytoluene as standard. The ethanol bark extract showed the highest reducing ability having an absorbance of 0.690 using 800 μg/ ml concentration at 700nm. The total antioxidant capacity by the phosphor molybdate method is expressed as α tocopherol equivalents. Among the extracts tested, the ethanol bark extract contains 8.3 μg Vitamin E equivalent/ mg, which has appeared twice greater antioxidant capacity than the leaf extract (4.2 μg Vitamin E equivalent/mg). The content of total phenolics (9.1 μg Pyro- catechol equivalent/mg) and total flavonoids (20.0 μg Quercetin equivalent/mg) in the ethanol bark extract was considerably higher than in the leaf extract. Based on the above results, the higher the flavonoid content, the higher the antioxidant capacity was very well observed with ethanolic bark extract. Hence the alcoholic extract of Wrightia tomentosa dried bark could be considered for the preparation of nutraceuticals with potent antioxidant effects suitable for the prevention of human disease.

WORLD JOURNAL OF PHARMACY AND PHARMACEUTICAL SCIENCES. 3. 964- 972. Background: Since free radicals play such an important role in the disease scenario of an individual, a thorough understanding of the various physiologically significant free radicals is of paramount importance before the search for the radical scavengers or the antioxidant principles to treat the physiological disorders caused by them such as inflammation. Objective: To explore newer antioxidant and anti-inflammatory agents from natural sources. Material and Methods: The antioxidant activity of the methanolic extract of Wrightia tinctoria leaves was determined by measuring its 1,1 diphenyl- 2- pycryl hydroxyl (DPPH) radical scavenging activity, reducing power and ability to inhibit lipid peroxidation. Anti-inflammatory activity was evaluated by using a carrageenan-induced rat paw edema model in healthy Wistar albino rats. Results and Discussion: Methanol extract exhibited strong total antioxidant activity. Concentrations of 50, 100, 200, 400, 800 and 1000μg /mL showed 52.34, 53.69, 53.69, 56.37, 58.60, and 61.07% inhibition of lipid peroxidation respectively. In addition, methanol extract had effective reducing power, and DPPH free radical scavenging activity at 400 μg/ mL, the same extract was also evaluated for its anti-inflammatory activity at doses 100, 200, and 400 mg/ kg. Conclusion: Methanolic extract showed predominantly significant activity in a dose-dependent manner, which is comparable to reference standard diclofenac sodium. Phytochemical studies indicated the presence of alkaloids and phenols are the major components in the extract and it may be further concluded that these constituents may be responsible for antioxidant and anti-inflammatory activity.
