The plant Indigofera aspalathoides is used by a large number of tribes in India for the treatment of various hepatic disorders and abscesses. The methanol extract of Indigofera aspalathoides (MEIA) was evaluated for its protective effects on gastric mucosal lesion in Wister albino rats against indomethacin, histamine and ethanol induced gastric mucosal damage. The response to MEIA was assessed using the ulcer index, thiobarbituric acid reactive substance (TBARS), and glutahione level. MEIA pretreatment showed protection against chemical induced gastric mucosal damage, a significant reduction in the ulcer index and TBARS activity and increase glutathione level as compared with that of standard drugs.

Antitumor and antioxidant status of Galega purpurea root in Ehrlich ascites carcinoma bearing Swiss albino mice

Gupta, M,Mazumder, UK,Gomathi, P Kyung Hee Oriental Medicine Research Center 2007 Oriental pharmacy and experimental medicine Vol.7 No.4

The present study was designed to determine the antitumor and antioxidant properties of methanol extract from the root of Galega purpurea (Papilionaceae) (MEGP) against Ehrlich Ascites Carcinoma (EAC) bearing Swiss albino mice. Acute and short-term toxicity studies were performed initially in order to ascertain the safety of MEGP. The effect of MEGP on the growth of transplantable murine tumor, life span of EAC bearing hosts and simultaneous alterations in the hematological profile and liver biochemical parameters (lipid peroxidation, antioxidant enzymes) were estimated. The MEGP showed decrease in tumor volume, packed cell volume and viable cell count and increases the nonviable cell count and mean survival time thereby increasing life span of EAC tumor bearing mice. Hematological profile reverted to more or less normal levels in extract treated mice. Treatment with MEGP decreased the levels of lipid peroxidation and increased the levels of glutathione, superoxide dismutase and catalase. The results suggested that the methanol extract of Galega purpurea root exhibited antitumor effect by modulating lipid peroxidation and augmenting antioxidant defense system in EAC bearing mice.

Hepatoprotective activity of methanol extracts of Glinus oppositifolius and Trianthema decandra against paracetamol induced liver damage

Gupta, M,Mazumder, UK,Haldar, PK,Manikandan, L,Senthilkumar, GP,Kandar, CC Kyung Hee Oriental Medicine Research Center 2007 Oriental Pharmacy and Experimental Medicine Vol.7 No.1

The plants, Trianthema decandra and Glinus oppositifolius are commonly used by tribal people in India for the treatment of liver diseases. Hepatoprotective activity of methanol extracts of Glinus oppositifolius and Trianthema decandra at the dose of 250 and 500 mg/kg body weight administered orally was evaluated against paracetamol induced liver damage in rats. Biochemical parameters such as serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum alkaline phosphatase, bilirubin, total serum protein, lipid peroxide and glutathione content of the liver were estimated to determine liver function and metabolism. From the biochemical observations, it was concluded that methanol extracts of Glinus oppositifolius and Trianthema decandra significantly restored the altered biochemical parameters towards normal condition in paracetamol induced liver damage.

The methanol extract of the root of Artanema sesamoides Family Scrophuilariaceae (MEAS) was investigated for possible analgesic and anti-inflammatory effects in animals. Three models were used to study the extract effects on nociception, which were acetic acid-induced writhing response, hot-plate method and the tail flick test in mice. The antiinflammatory effects were evaluated using carrageenan, dextran, histamine and serotonin induced rat paw oedema (acute) and cotton pellet induced granuloma (chronic) models in rats. Results of the study revealed that the extract exhibited significant (P < 0.001) analgesic effect at a dose of 50, 100 and 200 mg/kg b.w p.o in mice in all the models. In acute model, the MEAS also exhibited significant (P < 0.001) antiinflammatory effect in all the above mentioned doses. In chronic model (cotton pellet induced granuloma) the MEAS 200 mg/kg and indomethacin 10 mg/kg showed that inhibition of granuloma formation 25.0% and 47.7% respectively (P < 0.001). The MEAS and indomethacin were effectively preventing the transudation of the fluid. Thus, the present study revealed that the methanol extract of the root of Artanema sesamoides exhibited significant analgesic and antiinflammatory activity.

Antisteroidogenic activity of Raphanus sativus seed extract in female albino mice

PK Haldar,UK Mazumder,Sanjib Bhattacharya,L Manikandan,Siladitya Bhattacharya 경희대학교 융합한의과학연구소 2009 Oriental Pharmacy and Experimental Medicine Vol.9 No.4

The defatted methanol extract of Raphanus sativus Linn. (Cruciferae) seed (MERS) was evaluated for its antisteroidogenic potential in mature female Swiss albino mice. The methanol extract at the doses of 100 and 200 mg/kg body weight significantly elevated the levels of cholesterol and ascorbic acid contents which serve as a precursor for the synthesis of steroid hormones in ovaries. The extract also significantly inhibited glucose-6-phosphate dehydrogenase and Δ 5-3β-hydroxy steroid dehydrogenase, the two key enzymes involved in ovarian steroidogenesis. Hence the extract (MERS) exhibited significant antisteroidogenic activity. The defatted methanol extract of Raphanus sativus Linn.

Effects of methanol extracts of Cuscuta reflexa Roxb. stem and Corchorus olitorius Linn. seed on male reproductive system of mice

Pal, DK,Gupta, M,Mazumder, UK Kyung Hee Oriental Medicine Research Center 2009 Oriental pharmacy and experimental medicine Vol.9 No.1

The antifertility activity of methanol extract of Cuscuta reflexa Roxb. stem (MECR) and Corchorus olitorius Linn. seed (MECO) were studied on male Swiss albino mice. The extracts were found to decrease sperm count, percentage of motile sperm and testosterone level in treated mice when compared with vehicle control after 17 days of treatment. The weight of gonads, epididymis were decreased whereas no significant changes of the body weight of mice were observed after methanol extract treatments. The fertility test showed 100% negative result in MECR and MECO treated mice at medium and high dose level of treatment. MECR and MECO in low (25 mg/kg and 15 mg/kg, respectively), medium (50 mg/kg and 20 mg/kg, respectively) and high (75 mg/kg and 25 mg/kg, respectively) dose level caused a simultaneous fall in testicular ${\Delta}5$-$3{\beta}$-hydroxy steroid dehydrogenase and glucose-6-phosphate dehydrogenase activities which are involved in testicular steroidogenesis. Total cholesterol and ascorbic acid content in testis were increased significantly in gonads. The activities of lactate dehydrogenase, malic dehydrogenase and ascorbic acid oxidase were reduced whereas that of carbonic anhydrase was increased significantly in the testis of MECR and MECO treated mice. All these observations indicate that the methanol extract of C. reflexa stem and C. olitorius seed produced antifertility activity in sexually matured male mice, which may be due to inhibition of gonadal steroidogenesis. This activity may be attributed due to the presence of flavonoids and steroids, respectively.

Free radical scavenging property of Annona reticulata leaves

Susanta Kumar Mondal,Prerona Saha,NB Mondal,UK Mazumder 경희대학교 융합한의과학연구소 2008 Oriental Pharmacy and Experimental Medicine Vol.8 No.3

Annona reticulata belonging to the family Annonaceae is traditionally used as anthelmintic and it is reported to have anticancer activity. Free radicals are known to be involved in various types of diseases like cancer, diabetes, neurological disorders etc. The present study was aimed to evaluate free radical scavenging property of methanol extract of the leaves of Annona reticulata in some in vitro models e.g. DPPH, nitric oxide, superoxide and lipid peroxide radical model. The extract showed good dose-dependent free radical scavenging property in all the models. IC50 values were found to be 3.22, 170.01, 25.12 and 140.12 μg/ml respectively in DPPH, nitric oxide, superoxide and lipid peroxidation inhibition assays. Reductive ability of the extract was also tested based on potassium ferricyanide reduction where dose dependant reducing capability was observed. Measurement of total phenolic compounds by Folin-Ciocalteu’s phenol reagent indicated that 1mg of the extract contained 146.20 μg equivalent of pyrocatechol. The findings ascertain promising free radical scavenging property of the extract and the antioxidant property of the extract may be due to the high content of phenolic compounds.
