Cjanus cajan (L.) Millsp belonging to the family Fabaceae commonly known as pigeonpea or arhar. The present study conducted to assess the phytochemical and pharmacognostic in terms of organoleptic, fluorescence analysis and physicochemical parameters of seed coat and cotyledon of C. cajan. Differential extraction yielded of seed coat extracts of petether, chloroform, ethanol and aqueous shows 6.3%, 1.14%, 11.36% and 9.32% and cotyledon extracts of pet ether, chloroform, ethanol and aqueous shows 7.34 %, 4.25%, 10.45 % and 8.45 % respectively. Physicochemical parameters such as total ash, acid insoluble ash and water soluble ash of seed coat and cotyledon were found to be 14.5% and 11.5%, 8.35% and 7.36%, 2.11% and 3.39% respectively. Further the mineral elements like zinc, magnesium and copper content were found more in seed coat whereas, maximum content of iron were observed in cotyledon. The fluorescent analyses of powdered drug play an important role in the determination of quality and purity of the drug. Phytochemical analysis revealed the presence of glycosides, tannins, flavonoids, phenols, lignins,...

Different new compounds derived from 2-(3-flourobiphenyl-4-yl) propanohydrazide [2] as starting material were synthesized. Reaction [2] with maleic anhydride, succinic anhydride and phthalic anhydride gave the corresponding cyclicimides [3a-c]. The hydrazone derivatives [4a-d] were obtained by condensation of compound [2] with 2,4-dimethoxybenzaldehyde, 4-(N,N-dimethylamino)benzaldehyde, 3-hydroxybenzaldehyde and 2-hydroxybenzaldehyde. The cyclization of [2] with CS2 in presence potassium hydroxide and hydrazine hydrate gave 1,2,4-triazole compound [5], that condensation either with 2,4-dimethoxybenzaldehyde, 4-(N,N-dimethyl amino) benzaldehyde, 3-hydroxybenzaldehyde and 2-hydroxybenzaldehyde to give the corresponding Schiff-bases [6a-d]. The cyclization of hydrazone derivatives [4a-d] with phenyl isocyanate, maleic anhydride, succinic anhydride and phthalic anhydride gave the corresponding aza-β-lactams [7a-d], oxazepine [8,9,10 a-d]. The structures of new compounds are supported by FT-IR, 1H-NMR and 13C-NMR. Compounds [3c], [4c], [8d], [7d] and [4b] were evaluated in vivo for their anti-inflammatory activity comparable to the standard drug flurbiprofen. Compound 2-(2-hydroxyphenyl)-3-[2-(3-fluorobiphenyl-4-yl)] propan- amido-2,3-dihydro-1,3-oxazepine-4,7-dione [8d] showed anti-inflammatory activity more than the standard drug flurbiprofen, in the egg-albumin induced paw edema in...

Ayurveda is one of the oldest systems of medicine that uses plants and their extracts for treatment and management of various diseased states. Nyctanthes arbour – tristis Linn. (Family Oleaceae), which has long been used traditionally for various medicinal purposes in the Indian sub continent. Each part of the plant has some important medicinal value and is thus commercially exploitable. It is now considered as a valuable source of several unique products for the medicines against various diseases and also for the development of some industrial products. The present study is to focus on the potential phyto-chemicals and pharmacological activity of plant N. arbor – tristis. In view of this, the study was designed to investigate for chemical constituents, anti-cancer and anti-inflammatory activities of solvent leaf extracts. Phytochemical screening revealed the presence of alkaloid, steroids etc. The extract exhibited significant anti-cancer and anti-inflammatory properties and the observed biological activities in this study provide scientific validation of ethnomedicinal use of this...

Coronary heart disease (CHD) is widely prevalent both in the developed and developing countries and continues to be a leading cause of mortality despite recent advances in diagnostic facilities and treatment modalities. Recently it has been proposed that postprandial lipoprotein may be a better indicators of deranged lipoproteins metabolism and hence of atherosclerosis and CHD. The levels of non-fasting triglycerides are better at predicting future cardiovascular events than levels of fasting triglycerides. Furthermore, it is possible that non-fasting levels of lipids, lipoprotein, differ only minimally from levels in the fasting state simply because, most of the people consume for less fat at ordinary meals than during a fat tolerance test. The aim of the current study is to determine the postprandial (at the intervals of 2 hours and 4 hours) lipid parameters TC, TGL, HDL, LDL and VLDL levels in Coronary heart disease patients and to compare it with fasting lipid profile. 200 subjects were selected with 100 controls and 100 CHD cases. Statistical analysis was done. The study...

Diabetes is a chronic disease caused by inherited or acquired deficiency in insulin secretion and by decreased responsiveness of the organs to secreted insulin. The protective effect of aqueous extract of Plumeria Rubra was studied against streptozotocin (STZ) induced diabetes in rats. Plumeria rubra was administered orally at 3 dose levels (100, 200, 400mg/kg). Plumeria rubra extract and standard drug Glibenclamide (GB) (10mg/kg, p.o.) was administered to animals for 28 days. The blood glucose, serum cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein, body weight were assessed in the experimental animals. Plumeria rubra extract induced significant reduction (P < 0.001) in blood glucose levels in STZ induced diabetic rats. Plumeria rubra was found effective at all doses, although 200 mg/kg was found to be more effective and comparable with standard group. Additionally, histopathological examination of kidneys and pancreas showed that Plumeria rubra markedly ameliorated STZ induced renal tubular necrosis and pancreatic damage. Plumeria rubra exhibited significant antihyperglycemic activity in STZ induced diabetic rats. The results of the present...
