Abstract
Ageratina adenophora Spreng belongs to the Family Asteraceae is a very common weed and reported to possess diverse medicinal properties. Three compounds 1, 2 and 3 kaempherol diglycoside derivative (1), quercetin-3-O-beta-d-glucopyranoside (2) and quercetin-3-O-rutinoside (3) were isolated by column chromatography from the methanol extract of the flower part of A. adenophora Spreng and chemical structures identified by means of their spectral data. This is the first report for the presence of the flavanoids 1, 2 and 3 from the flowers of A. adenophora Spreng. Further this investigation enhances the chances for the possible utilization of A. adenophora Spreng as a medicinal herb.
