The aim of this study was to determine the major boactive constituents, trans-cinnamic acid and transcinnamaldehyde, and anti-oxidative activities of 50% aqueous methanol and water extracts of Cinnamomum burmannii Blume stem bark. Gas chromatography-mass spectrometry (GC-MS) was used to analyse the extracts. The content of trans-cinnalmadeyde quantified in the 50% aqueous methanol and water extracts were 50. Read More

New cyclohexyl epoxide and crotepoxide were isolated from the fruits of Piper attenuatum. The structure of the new metabolite was characterized as (2-benzoyl-1, 6-epoxy-3, 4, 5,-trihydroxy cyclohexyl) methanol benzoate along with crotepoxide using spectroscopic techniques.

The present study was performed to investigate the enzyme inhibitory and antidiabetic activities of the constituents isolated from Callistemon lanceolatus. The leaves of C. lanceolatus were extracted with successively with petroleum ether, dichloromethane and methanol. The dried dichloromethane and methanol extracts were subjected to fractionation and chromatographic separation, which led to the isolation of s Read More

Phytochemical investigation of the methanolic extract of the aerial parts of Artemisia absinthium Linn. (Asteraceae) yielded four new phytoconstituents characterized as stigmast-5,22-dien-3β-ol-21-oic acid-3β-glucopyranosyl-2'- octadec-9''-enoate (1); lanost-24-en-3β-ol-11-one-28-oic acid-21,23 α-olide-3β-D-glucopyranosyl-2'-dihydrocaffeoate-6'- decanoate (2); tricosan-14-on-1,4-olide-5-eicos-9'-enoate (3) and 3,1 Read More

Aedes aegypti is vector of Dengue and Yellow Fevers, a mosquito of public health importance. It is the most broadly disseminated urban species of mosquito in the world. Larval insecticide is one of the alternatives to control the mosquito dissemination. Temephos and Bacillus turinghiensis subsp. israelensis (Bti) are the larvicidal most used in the world to combat A. aegypti mosquito. In face of larvae resistance to Temephos and th Read More

The mineral content of commercially available different types of teas (premium black, flavored black, green and fruit tea) and the infusions produced from them with different type of water (distilled, spring and tap) were determined. Studied teas differed in contents of elements between their raw materials and infusions. Iron and copper exhibited the lowest efficiency of extraction by hot waters. There was a marked influe Read More

Plants are an important source of synthetic and herbal agents used in several pharmaceutical industries. Some of the prominent plant-derived compounds have played a major role in the development of several clinically useful anticancer agents such as vinblastine, vincristine, topotecan and paclitaxel (taxol). Himalayan plants, grown in high altitude are the rich source of various secondary metabolites such as anthraquino Read More

Problem statement: Bauhinia tomentosa is a medicinal plant popularly used as herbal remedy for various ailments in Ayurveda. However, the scientific basis for its medicinal use especially in pain and inflammation remains unknown. Therefore, the present study was designed to evaluate analgesic and antioxidant potential of the ethanol, methanol and aqueous extract of Bauhinia tomentosa (stem). Approach: The analgesi Read More
