Two new 3-hexenol glycosides from the calyces of Physalis alkekengi var. franchetii

Abstract

Two new hexenol glycosides, (Z)-hex-3-en-1-ol O-β-d-xylcopyranosyl-(1-6)-β -d-glucopyranosyl-(1-2)-β-d-glucopyranoside (1) and (E)-hex-3-en-1-ol O-β-d-xylcopyranosyl-(1-6)-β-d-glucopyranosyl-(1-2)-β-d-glucopyranoside (2), were isolated from the 50% ethanol elution of macroporous resin of Physalis alkekengi var. franchetii. Their structures were established by detailed spectroscopic analysis, including extensive 2D-NMR data. This is the first time to report the (Z) and (E) 3-hexenol glycosides from Physalis alkekengi var. franchetii.
