A new ent-kaurene beta-D-glucoside was isolated from Rabdosia rubescens, to
gether with the known compounds oridonin, ponicidin, and pedalitin, The str
ucture of new compound was determined, on the basis of spectral data and X-
ray crystallographic analysis, to be ent-7 beta,20-epoxy-kaur-16-ene-1 beta
,6 alpha,7 alpha,14 alpha,15 alpha-pentanol 1-O-beta-D-glucopyranoside.
