Abstract

Capsicum species are very important plants used as vegetable foods, spices and external medicines. We obtained novel acyclic diterpene glycosides, named capsianosides A-F (1-6) and I-V (7, 1b, 10, 9, 8) from various fruits of the Capsicum annuum species and their structures were elucidated by spectroscopic and chemical means. Capsianosides are classified into two groups, monomeric diterpene glycosides (capsianosides I-V) and their dimeric esters (capsianosides A-F).
