Two myricanol glycosides from Myrica rubra and revision of the structure of isomyricanone
摘要:
Two new diarylheptanoid glycosides were isolated from the stem bark of Myrica rubra (Myricaceae). On the basis of spectral and chemical evidence, their structures were established as myricanol 5-O-beta-D-glucopyranosyl-(1 --> 3)-beta-D-glucopyranoside and myricanol 5-O-alpha-L-arabinofuranosyl-(1 --> 6)-beta-D-glucopyranoside, respectively. The structure of isomyricanone was also reexamined chemically and physicochemically, and a revised structure is presented.
