Abstract

Five flavonoid glucuronides were obtained from the fruit of Helicteres isora, three of which were previously unknown compounds: Isoscutellarein 4′-methyl ether 8-O-β-o-glucuronide 6″-n-butyl ester, isoscutellarein 4′-methyl ether 8-O-β-o-glucuronide 2″, 4″-disulfate and isoscutellarein 8-O-β-D-glucuronide 2″,4″-disulfate. The structures were determined on the basis of spectroscopy and hydrolysis experiments.
