Abstract

Three new glycosides isolated from chloroform and   methanol extracts of the stem bark of F. hispida Linn which is   widely used in Manipur, India for controlling Diabetes mellitus,   as 3',4',5',5,7-pentamethoxy-4-acetyldelphinidin-3-O-α-Lrhamnoside   (2) 4',5,7-trimethoxy pelargonidin-6-C-glucopyranosyl-   3-O-α-L-rhamnoside (3) and 3',4',5',5,7-pentamethoxy   delphinidin-3-O-α-L-rhamnoside (4) along with known compounds   have been reported. A new ketoester, 24-ketopentacosyl-   γ-hydroxypentanoate (1) has also been isolated from the   petroleum extract. Compound 1 showed high inhibitory effect   on the growth of coliform organism and compound 2 had   antibiotic property in penicillium species.
