摘要
目的 研究巴西人参根Pfaffia glomerata(Spreng)Pedersen的化学成分.方法 巴西人参根 95%乙醇、50%乙醇提取物采用硅胶、D101 大孔树脂、葡聚糖凝胶LH-20、聚酰胺、ODS、制备型HPLC及重结晶进行分离纯化,根据理化性质及波谱数据鉴定所得化合物的结构.结果 从中分离得到 18 个化合物,分别鉴定为 1,2,4-苯三酚(1)、polypodine B(2)、(-)-丁香脂素-4-O-β-D-吡喃葡萄糖苷(3)、poststerone(4)、stachysterone B(5)、calonysterone(6)、taxisterone(7)、makisterone C(8)、20,22-O-(R-ethylidene)-20-hydroxyecdysone(9)、20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone(10)、shidasterone(11)、5α-20-hydroxyecdysone(12)、abutasterone(13)、25-hydroxydacryhainansterone(14)、甲基-α-D-呋喃果糖苷(15)、甲基-β-D-呋喃果糖苷(16)、竹节参皂苷Ⅳa甲酯(17)、尿嘧啶核苷(18).结论 化合物 1～6、8～16、18 首次从巴西人参中分离得到,化合物 1、3～6、8～16、18 首次从珐菲亚属植物中分离得到.
Abstract
AIM To study the chemical constituents from the roots of Pfaffia glomerata(Spreng)Pedersen.METHODS The 95%and the 50%ethanol extract from P.glomerata were isolated and purified by silica gel,D101 macroporous resin,sephadex LH-20,polyamide,ODS,preparative HPLC and recrystallization,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Eighteen compounds were isolated and identified as 1,2,4-benzenetriol(1),polypodine B(2),(-)-syringaresinol-4-O-β-D-glucopyranoside(3),poststerone(4),stachysterone B(5),calonysterone(6),taxisterone(7),makisterone C(8),20,22-O-(R-ethylidene)-20-hydroxyecdysone(9),20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone(10),shidasterone(11),5α-20-hydroxy-ecdysone(12),abutasterone(13),25-hydroxydacryhainansterone(14),methyl-α-D-fructofuranoside(15),methyl-β-D-fructofuranoside(16),chikusetsusaponin Ⅳamethyl ester(17),uridine(18).CONCLUSION Compounds 1-6,8-16,18 are isolated from P.glomerata for the first time,and compounds 1,3-6,8-16,18 are isolated from the genus of Pfaffia for the first time.
