Three New Acyclic Diterpene Glycosides from the Aerial Parts of Paprika and Pimiento

Abstract

Paprika and pimiento are used as vegetables and spices. We have obtained three new acyclic diterpene glycosides, called capsianosides XVII (1), V methyl ester (2) and XIV (3) together with capsianosides I¹⁾ and II²⁾ from the aerial parts of paprika and pimiento. The structures of these compounds have been established by ¹H- and ¹³C-NMR spectra and two-dimensional NMR methods.
