Two new diarylheptanoid glycosides (1 and 2) were isolated together with vanillic acid and six known triterpenoids, maslinic acid, alphitolic acid, arjunolic acid, myricolal, oleanolic acid and oleanolic acid acetate, from the stem bark of Myrica rubra SIEB. et ZUCC. (Myricaceae). On the basis of spectral and chemical evidence, the structures of 1 and 2 were established as myricanol 5-O-β-D-(6'-O-galloyo)-glucopyranoside and myricanol 5-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside, respectively.
