白木香化学成分研究(英文)

Chemical constituents from Aquilaria sinensis(Lour.) Gilg

对白木香Aquilaria sinensis(Lour.)Gilg茎木的化学成分进行研究。应用多种色谱方法进行分离和纯化,波谱技术确定化合物的结构。从白木香茎木中分离并鉴定了13个化合物,分别为爵床脂素A(1),justidin F(2),刺五加酮(3),(+)丁香树脂酚(4),丁香脂双葡萄糖苷(5),无梗五加苷B(6),curuilignan D(7),丁香素(8),4-羟基-3,5-二甲氧基酚苷(9),3,4,5-三甲氧苯基-1-O-β-D-吡喃葡萄糖苷(10),3,4,5-三甲氧苯基-1-O-β-D-呋喃芹糖-(1″→6′)-β-D-吡喃葡萄糖苷(11),7-ketositosterol(12),7-oxo-5,6-dihydrostigmasterol(13)。以上化合物均为首次从沉香属植物中分离得到。

To investigate the chemical constituents of the stems ofAquilaria sinensis （Lour.） Gilg, the separation and purification were performed by solvent extraction, repeated chromatography on silica gel, Sephadex LH-20 and prep-HPLC. The structures were determined by spectrum analysis. Thirteen known compounds were isolated and their structures were identified as justicidin A （1）, justidin F （2）, ciwujiatone （3）, （＋） syringaresinol （4）, syringaresinol-4,4＇-di-O-13-D-glucopyranoside （5）, syringaresinol-4＂O-β-D- glucopyranoside （6）, curuilignan D （7）, syringin （8）, koaburaside （9）, 3,4,5-trimethoxyphenyl-l-O-β-D-glucopyranoside （10）, 3,4,5-trimethoxyphenyl-l-O-13-D-apiofuranosyl-（1 ＂→6＇） glucopyranoside （11）, 7-ketositosterol （12）, 7-oxo-5,6-dihydrostigmasterol （13）. All the compounds described above were isolated from genus Aquilaria for the first time.
