Abstract

The aerial part of Aster scaber THUNB. (Asteraceae) yielded two new monoterpene peroxide glycosides, (3S)-3-O-(3',4'-diangeloyl-β-D-glucopyranosyloxy)-7-hydroperoxy-3,7-dimethylocta-1,5-diene (1) and (3S)-3-O-(3',4'-diangeloyl-β-D-glucopyranosyloxy)-6-hydroperoxy-3,7-dimethylocta-1,7-diene (2), and five known compounds, α-spinasterol (3), germacra-4(15),5,10(14)-triene-1β-ol (4), 7-methoxy-4(15)-oppositen-1β-ol (5), 6α-methoxy-4(15)-eudesmane-1β-ol (6) and α-spinasterol 3-O-β-D-glucopyranoside (7). The structures were established by chemical and spectroscopic methods.
