Two new triterpenoid alcohols, 1 and 2, were isolated from the fresh rhizomes of Polypodiodes formosana. Using spectral and chemical evidences structures of 1 and 2 were established as 6α-hydroxyachilla-9,13,17,21-tetraene-tetraene and 8α-hydroxypolypoda-13,17,21-triene with their absolute configuration.
从新鲜的Polypodiodes formosana的根茎中分离出两种新的三萜类醇1和2。利用光谱和化学证据,将1和2的结构以其绝对构型建立为6α-羟基achilla-9,13,17,21-四烯-四烯和8α-羟基多聚体13,17,21-三烯。
