New Acylic Diterpene Glycosides, Capsianosides VI, G and H from the Leaves and Stems of Capsicum annuum L.

Abstract

Capsicum species are very important plants used as vegetable foods, species and external medicines. In the preceding paper, we disclosed the occurrence of novel acylic diterpene glycosides from fruits of the Capsicum species. We now obtained three new acyclic diterpene glycosides, names capsianosides VI (1), G (2) and H (3), along with capsianosides II, A, B, C and D from the leaves and steam of the Capsicum annuum species, and their structures were elucidated by spectroscopic and chemical means.
