中文摘要: |
本文研究鲜品百合鳞茎正丁醇部位的化学成分。采用硅胶柱层析、大孔树脂、葡聚糖凝胶和半制备高效液相色谱仪等分离方法对鲜品百合鳞茎95%乙醇提取物的正丁醇部位进行分离纯化,并结合理化性质和NMR等波谱学技术对化合物进行结构鉴定。从鲜品百合鳞茎正丁醇部位分离得到16个化合物,分别鉴定为:3'-O-feruloyl-6-O-(4-O-glucopyranosyl) feruloylsucrose(1)、3', 6-di-O-feruloylsucrose(2)、王百合苷A(3)、王百合苷B(4)、王百合苷C(5)、王百合苷E(6)、王百合苷F(7)、2, 2- [bis-4- (2,3- dihydroxypropoxy) phenyl] propane(8)、黄芩苷(9)、芦丁(10)、齐墩果酸(11)、β-谷甾醇(12)、儿茶素(13)、表儿茶素(14)、山柰酚(15)和槲皮素(16)。其中,化合物1、2、4、6、7和9为首次从百合属中分离得到。 |
英文摘要: |
To study the chemical constituents of n-butanol extract from the fresh bulbs of Lilium brownii, the n-butanol portion of 95% ethanol extract from the fresh bulbs of Lilium brownii was separated and purified by column chromatography such as silica gel column chromatography, macroporous resin, sephadex LH-20 and semi-preparative HPLC, and the structures of the isolated compounds were identified by combining physical and chemical properties and NMR spectroscopy. Sixteen compounds were isolated and identified as 3′-O-feruloyl-6-O-(4-O-glucopyranosyl) feruloylsucrose (1), 3′,6-di-O-feruloylsucrose (2), regaloside A (3), regaloside B (4), regaloside C (5), regaloside E (6), regaloside F (7), 2,2-[bis-4-(2,3-dihydroxypropoxy) phenyl] propane (8), baicalin (9), rutin (10), olonolic acid (11), β-sitosterol (12) , catechin(13), epicatechin (14), kaempferol (15), and quercetin (16) respectively. Among them,compounds 1, 2, 4, 6, 7 and 9 were first isolated from the genus of Lilium. |
