Purpose: To evaluate the ethanol extracts of the flowers, leaves, and stems of Centaurea tchihatcheffii Fischer & C.A. Meyer (Asteraceae) for their anti-inflammatory and analgesic activities in male Swiss albino mice. Methods: For the evaluation of anti-inflammatory activity, hind paw oedema was induced in the mice with carrageenan and prostaglandin-E2 (PGE2 ) and the mice received either 100 a...

The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...

Background:α-Glucosidase Inhibition can significantly prevent glucose uptake after meal, and helps in controlling of some adverse effects in diabetics. So determination of α-Glucosidase inhibitory effect and antioxidant activity of the Haplophyllum acutifolium and Ferula haussknechtii aerial organs was the aim of this study.Methods:Inhibitory effect of hexane extracts from dif...

Studies evaluated the effects of hexanic extracts from the fruits and flowers of Clusia fluminensis and the main component of the flower extract, a purified benzophenone (clusianone), against Aedes aegypti. The treatment of larvae with the crude fruit or flower extracts from C. fluminensis did not affect the survival ofAe. aegypti (50 mg/L), however, the flower extracts significantly delayed de...
