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-3α,16α,17-triol-19-al 3- O -[5- O -vanilloyl-β- D -apiopyranosyl(1→6)]-β- D -glucopyranoside (1) and ent -kauran-3α,16α,17-triol-19-al 3- O -[5- O-E -sinapoyl-β- D -apiopyranosyl(1→6)]-β- D -glucopyranoside (2).
