目的研究美丽蛇根草Ophiorrhiza rosea的化学成分。方法美丽蛇根草用90%甲醇浸提,然后采用硅胶、氧化铝和大孔吸附树脂、MCI几种柱色谱进行分离纯化,根据波谱分析(MS1、H-NMR和13C-NMR)鉴定化学结构。结果分离得到11个化合物,结构分别鉴定为Harman(Ⅰ)、2-羟基-3-羟甲基蒽醌(Ⅱ)、1-羟基-2-羟甲基蒽醌-3-O-β-D-葡萄糖苷(Ⅲ)、1-羟基-2-羟甲基蒽醌-3-O-β-D-樱草糖苷(Ⅳ)、乌苏酸(Ⅴ)、3α,19,24-三羟基-12-烯-28-乌苏酸(Ⅵ)、19,23-二羟基-3-氧代-12-烯-28-乌苏酸(Ⅶ)、3α,24-二羟基-12-烯-28-齐墩果酸(Ⅷ)、3,20-环氧-3α,16-二羟基-15-氧代-7-海松烯-19,6-内酯(Ⅸ)、β-豆甾醇-3-O-β-D-葡萄糖苷(Ⅹ)、β-谷甾醇(Ⅺ)。结论对美丽蛇根草的化学成分进行研究发现其含有大量的生物碱Harman、多种三萜和蒽醌。

Objective To study the chemical constituents of Ophiorrhiza rosea.MethodsThe chemical constituents in O.rosea were extracted with 90% methanol,isolated and purified by column chromatography on silica gel,alumina gel,MCI gel,and macroporous resin adsorption.All the compounds were identified based on spectral analyses(MS,1H-NMR,and 13C-NMR).Results Eleven compounds were isolated from O.rosea.They were characterized as Harman(Ⅰ),2-hydroxy-3-hydroxymethylanthraquinone(Ⅱ),1hydroxy-2-hydroxymethylanthraquinone-3-O-β-D-glucoside(Ⅲ),1-hydroxy-2-hydroxymethylanthraquinone-3-O-β-D-primeveroside(Ⅳ),ursolic acid(Ⅴ),3α,19,24trihydroxy-12-ursen-28-oic acid(Ⅵ),19,23-dihydroxy-3-oxo-12-ursen28-oic acid(Ⅶ),3α,24-dihydroxy-12-oleanen-28-oic acid(Ⅷ),3,20-epoxy-3α,16-dihydroxy-15-oxo-7-pimaren-19,6-olide(Ⅸ),β-stigmasterol-3-O-β-D-glucoside(Ⅹ),and β-sitosterol(Ⅺ).Conclusion This is the first report on the chemical constituents of O.rosea to find that it contains plentiful alkaloid Harman,multiform of triterpenes and anthraquinones.
