title: ent-Kaurane glycosides from Tricalysia okelensis.
abstract: Tricalysiosides V and W, two new ent-kaurane glycosides with an acylated disaccharide moiety at the C-3 position, were isolated from the roots of Tricalysia okelensis and their structures established by spectroscopic and chemical methods as ent-kauran-3alpha,16alpha,17-triol-19-al 3-O-[5-O-vanilloyl-beta-D-apiopyranosyl(1-->6)]-beta-D-glucopyranoside (1) and ent-kauran-3alpha,16alpha,17-triol-19-al 3-O-[5-O-E-sinapoyl-beta-D-apiopyranosyl(1-->6)]-beta-D-glucopyranoside (2).
