CHALCONES FROM NYCTANTHUS ARBORTRISTIS AND THEIR ANTIMICROBIAL ACTIVITY
Dr. Surabhi Yadav* and Dr. Preeti Singh
The present study deals with isolation as well as characterization of two new biologically active chalcones which has been isolated from extracts of the leaves of Nyctanthus arbortristis. Compound I was isolated from ethanol fraction and characterized as 4â€™-hydroxy, (5, 5â€™ diprenyl) 4-methoxy chalcone, and compound II was isolated from water fraction and characterized as 3, 4, 4â€™ trihydroxy [5-5â€™ bis-O-(7-methyl 5-oxooctanoate) Î²- D Glucosidic] Chalcone. Their structures were determined by several color reaction, spectral analysis and chemical degradations. The study revealed their antimicrobial and antifungal potential.
Keywords: Antimicrobial activity; Chalcone; Nyctanthus arbortristis.
