Studies on the Constituents of Lonicera Species. VII. Three New Polyhydric Alcohol Glycosides from the Leaves of Lonicera gracilipes var. glandulosa MAXIM.

Abstract

Three new polyhydric alcohol glycosides (1-3) were isolated from the leaves of Lonicera gracilipes var. glandulosa MAXIM. (Caprifoliaceae). Their structures were determined to be erythritol-1-O-(6-O-trans-caffeoyl)-β-D-glucopyranoside (1), 1, 2, 3, 4-tetrahydroxy-2-methylbutane-4-O-(6-O-trans-caffeoyl)-β-D-glucopyranoside (2) and arabitol-5-O-(6-O-trans-caffeoyl)-β-D-glucopyranoside (3) on the basis of chemical and spectral data.
