松塔化学成分的研究

Studies on chemical constituents of Pinus armandii

摘要: 目的研究华山松松塔的化学成分。方法用溶剂法和色谱法分离化合物，波谱法鉴定其结构。结果分离得到4个二萜类化合物，其结构鉴定为7-oxo-12α,13β-dihydroxyabiet-8(14)-en-18-oic acid (I), 7-oxo-13β-hydroxyabiet-8(14)-en-18-oic acid (II), 8(14)-podocarpen-13-on-18-oic acid (III)和lambertianic acid (IV)。结论I为新化合物，其结构鉴定为7-oxo-12α,13β-dihydroxyabiet-8(14)-en-18-oic acid，化合物II，III为首次从该植物中分离得到。

Abstract: AimTo study chemical constituents from pine cone of Pinus armandii Franch.Methods The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral analysis.ResultsFour compounds were identified as 7-oxo-12α,13β-dihydroxyabiet-8(14)-en-18-oic acid (I), 7-oxo-13β-hydroxyabiet-8 (14)-en-18-oic acid (II), 8 (14)-podocarpen-13-on-18-oic acid (III) and lambertianic acid (IV).ConclusionCompound I is a new diterpenoid and compounds II, III were isolated from this plant for the first time.
