Abstract

From Argylia radiata a non-glycosidic iridoid, the (4aS, 7S, 7aS)-7-hydroxy-7-methyl-1,4a,5,6,7,7a-heptahydrocyclopenta[c]pyran-3(4H)-one, and a bisiridoid, derived from the junction of catalpol and 7-deoxyloganic acid, were isolated.

Key words

Argylia radiata - non-glycosidic iridoid - bisiridoid - argyol - radiatoside D - structure elucidation
