A new ent-pimarane-type diterpenoid glucoside , along with eight known same skeleton type were isolated from the ethanol extract of Siegesbeckia pubescens Makino by means of various chromatographic techniques (silica gel, RP-8, Sephadex LH-20, Pre-HPLC). Their structures were elucidated on the ba sis of spectroscopic analyses and the new one identified as ent-15-methylene-2α,16,19-trihydroxy-pimar-8(14)-ene-19-O-β-D-glucopyranoside.KEYWORDS
