通过大孔吸附树脂、正相硅胶、Sephadex LH-20柱色谱,以及反相闪式柱色谱和HPLC等多种分离方法相结合,从信宜润楠95%乙醇提物中首次分离得到10个苷类化合物;借助红外、质谱和核磁共振等波谱学分析方法分别鉴定为淫羊藿次苷B1(1),boscialin-3-O-β-D-glucopyranoside(2),pisumionoside(3),异落叶松脂素9’-O-β-D-吡喃木糖苷(4),5’-甲氧基异落叶松脂素9’-O-β-D-吡喃木糖苷(5),南烛木树脂酚9’-O-β-D-吡喃木糖苷(6),(E)-4-羟基苯丙-7-烯4-O-β-D-吡喃葡萄糖苷(7),(E)-4-羟基-3-甲氧基苯丙-7-烯4-O-α-L-吡喃鼠李糖基-(1→6)-β-D-吡喃葡萄糖苷(8)、4-羟基-3-甲氧基苯丙-8-烯4-O-β-D-吡喃木糖基-(1→6)-β-D-吡喃葡萄糖苷(9)和4-羟基-3,5-二甲氧基苯丙-8-烯4-O-α-L-吡喃鼠李糖基-(1→6)-β-D-吡喃葡萄糖苷(10)。
By means of macroporous adsorption resin, normal phase silica gel, Sephadex LH-20 column chromatography, reversed-phase flash column chromatography and HPLC and other separation methods, 10 Glycosides were identified as boscialin-3-O-β-D-glucopyranoside (2) and pisumionoside (3) by means of IR, MS and NMR spectroscopy. Lactomycin 9’-O-β-D-xylopyranoside (4), 5’-methoxyisorhinol 9’-O-β-D-xylopyranoside (5) (E) -4-hydroxybenzene-7-ene 4-O-β-D-glucopyranoside (7), (E) 4-O-α-L-rhamnopyranosyl- (1 → 6) -β-D-glucopyranoside (8) 4-O-β-D-xylopyranosyl- (1 → 6) -β-D-glucopyranoside (9) and 4-hydroxy -3,5-dimethoxybenzene-8-ene 4-O-α-L-rhamnopyranosyl- (1 → 6) -β-D-glucopyranoside (10).
