目的研究伸筋草Lycopodii Herba(石松Lycopodium japonicum全草)的化学成分。方法利用硅胶柱色谱、Sephadex LH-20柱色谱以及制备型HPLC等技术进行分离纯化,通过理化性质和波谱数据鉴定化合物结构。结果从伸筋草中分离得到13个化合物,其中生物碱类1个,三萜类化合物4个,其他类型化合物8个,分别为白桦脂醇(1)、邻苯二甲酸二(2-乙基)己酯(2)、α-芒柄花素(3)、16-oxo-3α-hydroxyserrat-14-en-21β-ol(4)、3-表伸筋草醇(5)、(24S)-24-甲基胆甾醇(6)、lycopodiin A(7)、毛樱桃烷B(8)、α-玉柏碱(9)、石松醇(10)、千层塔烯二醇(11)、(-)-1-(4′-hydroxy-3′-methoxyphenyl)-2-(4″-hydroxy-3″-methoxyphenyl)propan-3-ol(12)、13,13-ethylenedioxy-15,16-dinorlabd-7-en-6β-ol(13)。结论其中化合物1、2、6、8、11-13为首次从该植物中分离得到,其中化合物2、6、8、12为首次从该属植物中分离得到。
Objective To study the chemical constituents in the whole herb of Lycopodium japonicum. Methods The chemical constituents were separated and purified by silica gel, Sephadex LH-20 column chromatography, and preparative HPLC. Their structures were identified by various spectroscopic analyses. Results Thirteen compounds were obtained from the whole herb of L. japonicum by the chromatographic methods on silica gel, ODS, and Sephadex LH-20 column, and preparative HPLC. According to physicochemical properties and spectral data, these compounds were identified as betulin(1), di-(2-ethylhexyl) phthalate(2), α-onocerin(3), 16-oxo-3α-hydroxyserrat-14-en-21β-ol(4), 3-epilycoclavanol(5),(24S)-24-methyl cholesterol(6), lycopodiin A(7), tomentosanan B(8), α-obscurine(9), lycoclavanol(10), serratenediol(11), 1, 2-diarylpropane-3-ol(12), and 13, 13-ethylenedioxy-15, 16-dinwlabd-7-en-6β-ol(13). Conclusion Compounds 1, 2, 6, 8, and 11—13 are isolated from this plant for the first time. Compounds 2, 6, 8, and 12 are isolated from the plants of this genus for the first time.
