Two new flavonoid glycosides, takakin 8-O-β-D-glucuronide 6″methyl ester (2), takakin 8-O-β-D-glucuronide 2″-sodium sulfate (3) together with a known flavonoid glycoside, takakin 8-O-β-D-glucuronide were isolated from the root bark of Helicteres angustifolia (Sterculiaceae). The stru- ctures of these compounds were established on the basis of spectrosco- pic and chemical evidence

A new sesquiterpene lactone glucoside, 8-epicrepioside G(1) together with two known compounds, 8-epidesacylcynaropicrin glucoside (2) and ixerin D (3) were isolated from the whole plant of Ixeris chinensis. Their structures were determined on the basis of chemical and spectro- scopic evidence. Compounds (1),(2) and (3) taste of strong bitterness

A new withanolide as a topoisomerase II inhibitor, withangulatin A was isolated from the whole herb of Physalis angulata L. (Solanaceae). The structure of withangulatin A was established as (20S, 22R)-15α-acetoxy-5β,6β-epoxy-4β,14α-dihydroxy-1-oxowitha-2,16,24-trienolide on the basis of spectroscopic and chemical evidence
