Abstract
A phytochemical investigation on the 70% EtOH extract from the dry fronds of Diplopterygium rufopilosum afforded two new labdane-type diterpene glycosides, (3β,13S)-3-O-β-d-glucopyranosyl-13-O-α-l-rhamnopyranosyl-labda-8(17),14-diene (1) and (3β,13S)-3-O-α-l-rhamnopyranosyl-13-O-[6-O-acetyl-β-d-glucopyranosyl-(1 → 4)-2-O-acetyl-α-l-rhamnopyranosyl]-labda-8(17),14-diene (2). Their structures were determined on the basis of chemical method and spectroscopic analyses, including 1D and 2D NMR (COSY, HMQC, HMBC, and NOESY) and HR-ESI-MS analyses.
