Baliospermum montanum (Wild.) Muell. Arg., (Euphorbiaceae) is a well known medicinal plant which is used in treatment of various diseases. The present study was focussed on the separation and investigation of the phytochemical compounds from ethanolic extract by GC-MS technique. The mass spectra of thecompounds found in the extract were matched with the National Institute of Standards and Technology (NIST) library. The ethanolic extract revealed the presence of 30 bioactive compounds. The major and minor phytochemical compounds are 2,15-Dithia[3](9,10)anthracenol[3](2,6)pyridinophane,1,2,3,4-tetrahydro showed the highest peak 9.32% followed by phytol-9.08%, Neophytadiene-7.38%, 8,11-Octadecadienoic acid, methyl ester (CAS)-7.06%, 4-ethyl-6-[2-(methoxycarb onyl)ethenyl]-7-[2-(methoxycarbonyl)ethyl]1,3,5,8-tetramethyl-2-vinylporphyrin-6.72%, 2-pentafluorophenylpropanal-6.43%,4,4'-Isopropylidene-bis-(2-cyclo hexyl phenol)-5.91% etc.. Further pharmacological studies are needed to find out the medicinal aspect of these compounds.
The study revealed the antidiabetic activity of the ethanol extract of Exacum wightianum Arn. (Gentianaceae) in streptozotocin induced diabetic rats. The pilot studies were carried after oral administration at doses of 100, 200, 500 and 1000 mg/kg b.wt. in sub-acute study. In diabetic induced rats fed with the extract at 100 and 200 mg/kg body b.wt. The fasting plasma glucose levels were reduced to near normal body and liver weight were found to be increased. Whereas blood glucose, protein, albumin and creatinine levels were estimated after two weeks. The extract significantly inhibited the induction of albuminuria, proteinemia and uremia. The present study clearly indicated a significant antidiabetic activity with the ethanol extract of E. wightianum supports the traditional usage of the plant by Ayurvedic physicians for the control of diabetes. The extract could be useful in preventing the incidence of long term complications of diabetes mellitus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
