TITLE:
摘要: 目的:研究蜈蚣草全草石油醚部位的化学成分。方法:采用硅胶柱色谱、凝胶柱色谱、重结晶和薄层色谱法对蜈蚣草全草石油醚部位的化学成分进行分离纯化,根据理化性质、氢谱和碳谱数据鉴定化合物结构。结果:从蜈蚣草全草石油醚部位分离、鉴定得到11个化合物,分别为(2R)-acetyl pterosin B(Ⅰ)、十六烷酸(Ⅱ)、何帕-22(29)-烯(Ⅲ)、表木栓醇(Ⅳ)、羽扇豆酮(Ⅴ)、齐墩果-18-烯-3-酮(Ⅵ)、豆甾醇(Ⅶ)、β-谷甾醇(Ⅷ)、22-羟基何帕烷(Ⅸ)、麦角甾醇(Ⅹ)、β-谷甾醇乙酸酯(Ⅺ)。结论:化合物Ⅰ~Ⅶ和Ⅸ~Ⅺ为首次从该植物中分离得到,可为深入研究蜈蚣草的生物活性药效物质基础、丰富其化学成分研究资料提供理论依据。
ABSTRACT: OBJECTIVE: To study the chemical constituents from the petroleum ether part from whole herbs of Pteris vittata. METHODS: The petroleum ether part from whole herbs of P. vittata was separated and isolated by silica gel column, gel column, recrystallization and TLC. The structures of the compounds were identified according to physicochemical properties and spectrum data (1H-NMR and 13C-NMR). RESULTS: A total of 11 compounds were isolated and identified from the petroleum ether part from whole herbs of P. vittata, as (2R)-acetyl pterosin B (Ⅰ), palmitic acid (Ⅱ), hop-22(29)-ene (Ⅲ), epifriedelanol (Ⅳ), lupenone (Ⅴ), olean-18-en-3-one (Ⅵ), stigmasterol (Ⅶ), β-sitosterol (Ⅷ), 22-hydroxyhopane (Ⅸ), ergosterol (Ⅹ), β-sitosterol acetate (Ⅺ). CONCLUSIONS: Compounds Ⅰ-Ⅶ and Ⅸ-Ⅺ are isolated from this plant for the first time, and can provide theoretic reference for further studying bioactive pharmacodynamic substances in P. vittata and enriching chemical component data.
