Abstract
Five flavonoid glucuronides were obtained from the fruit of Helicteres isor a, three of which were previously unknown compounds: isoscutellarein 4'-met hyl ether 8-O-beta -D-glucuronide 6"-n-butyl ester, isoscutellarein 4'-meth yl ether 8-O-beta -D-glucuronide 2", 4"-disulfate and isoscutellarein 8-O-b eta -D-glucuronide 2",4"-disulfate. The structures were determined on the b asis of spectroscopy and hydrolysis experiments. (C) 2001 Elsevier Science Ltd. All rights reserved.
