目的研究过山蕨(Camptosorus sibiricus Rupr.)水提物的化学成分。方法通过正相硅胶、MCI树脂、Sephadex LH-20、制备薄层色谱和反相HPLC等多种色谱技术,对过山蕨水煎煮提取物的化学成分进行分离纯化,通过波谱数据分析,鉴定了化合物的结构。结果共分离得到9个化合物,分别鉴定为:苄醇-O-β-D-吡喃葡萄糖苷(1)、3,5-二甲氧基-4-羟基-苯甲酰基-O-β-D-吡喃葡萄糖酯(2)、4-羟基-3-甲氧苯基-O-β-D-吡喃葡萄糖苷(3)、3,5-二甲氧基-4-羟基苯基-O-β-D-吡喃葡萄糖苷(4)、4-(2-羟乙基)-2-甲氧苯基-O-β-D-吡喃葡萄糖苷(5)、银桦苷G(6)、2-(4-羟苯基)乙基-O-β-D-吡喃葡萄糖苷(7)、2-(3,4-二羟基苯基)乙基-O-β-D-吡喃葡萄糖苷(8)、2-羟基-5-(2-羟乙基)-苯基-O-β-D-吡喃葡萄糖苷(9)。结论化合物1-9均为从过山蕨属中首次分离得到。
Objective To study the chemical constituents of aqueous extracts of Camptosorus sibiricus Rupr. Methods The chemical constituents of the water extract of Pseudostellariae Rhynchosae were isolated and purified by normal phase silica gel, MCI resin, Sephadex LH-20, preparative thin layer chromatography and reverse phase HPLC. The chemical constituents were isolated and purified by spectral data analysis The structure of the compound. Results Nine compounds were isolated and identified as benzyl alcohol-O- β -D-glucopyranoside (1), 3,5-dimethoxy-4-hydroxy-benzoyl- D-glucopyranoside (2), 4-hydroxy-3-methoxyphenyl-O-β-D-glucopyranoside (3), 3,5-dimethoxy-4-hydroxyphenyl- Glucopyranoside (4), 4- (2-hydroxyethyl) -2-methoxyphenyl-O-β-D-glucopyranoside (5) 6) 2- (4-hydroxyphenyl) ethyl-O-β-D-glucopyranoside (7) Glucopyranoside (8), 2-hydroxy-5- (2-hydroxyethyl) -phenyl-O-β-D-glucopyranoside (9). Conclusion Compounds 1-9 were isolated from the genus Porphyridium for the first time.
