研究红茴香茎部甲醇部位的化学成分。运用HP-20、反相硅胶柱色谱、Sephadex LH-20、高效制备液相等分离技术,对甲醇部位进行分离纯化,通过质谱(MS)、波谱数据分析(1H,13C-NMR)进行结构鉴定。从甲醇部位分离5个化合物,分别鉴定为苯甲醇-O-β-D-吡喃葡萄糖苷(1),4-羟基-苯乙醇-O-β-D-吡喃葡萄糖苷(2),3-甲氧基-4-羟基-苯丙醇-O-β-D-吡喃葡萄糖苷(3),3-甲氧基-4-O-β-D-吡喃葡萄糖基-苯甲酸甲酯(4),4-O-β-D-吡喃葡萄糖基-苯甲酸甲酯(5)。以上化合物均为首次从该植物中分离得到。
Study the chemical composition of the methanol part of red fennel stem. The methanol fractions were separated and purified by HP-20, reversed-phase silica gel column chromatography, Sephadex LH-20 and HPLC. The structures were elucidated by mass spectrometry (MS) and spectroscopic data (1H, 13C-NMR) . Five compounds were isolated from the methanol site and identified as benzyl alcohol-O- β -D-glucopyranoside (1), 4-hydroxy-phenethyl alcohol-O- β -D- glucopyranoside (2), 3 Methoxy-4-hydroxy-phenylpropanol-O-β-D-glucopyranoside (3), methyl 3-methoxy-4-O- β -D-glucopyranosyl-benzoate (4), 4-O-β-D-glucopyranosyl-benzoate (5). The above compounds were isolated from this plant for the first time.
