小远志化学成分研究

Chemical Constituents of Polygala sibirica L. var. megalopha Fr.

对小远志化学成分进行研究,从中分离得到12个化合物,依据理化性质及波谱数据分析,分别鉴定为:丁香醛(1),4-羟基-3,5-二甲氧基-苯乙酮(2),8-羟基-1-(4-羟基-3-甲氧基)苯基-1-丙酮(3),水杨酸(4),反式芥子酸甲酯(5),3,4,5-三甲氧基肉桂酸甲酯(6),3,4,5-三甲氧基肉桂酸(7),5-羟基-4',6,7-三甲氧基黄酮(8),芥子醇-4-O-β-D-芹糖-(1→2)-β-D-吡喃葡萄糖苷(9),(±)-丁香脂素(10),(+)-梣皮树脂醇(11),(±)-松脂醇(12)。除化合物4外,其它化合物均为首次从该植物中分离得到。

Twelve compounds were isolated from the Polygala sibirica L.var. megalopha Fr. On the basis of the physico-chemical properties and spectral data, they were identified as syringaldehyde（1）, 4-hydroxy-3, 5-dimethoxyacetophenone（2）, evofolin-A（3）, salicylic acid（4）, trans-sinapic acid methyl ester（5）, 3,4,5-trimethoxycinnamic acid methyl ester（6）, 3,4,5-trimethoxycinnamic acid（7）, 5-hydroxy-4＇,6,7-trimethoxy-flavone（8）, sinapylalcohol-4-O-β-D-apiofuranosyl-（1→2）-β-D-glucopyranoside（9）,（±）-syringaresinol（10）,（＋）-medioresinol（11）,（±）-pinoresinol（12）. All compounds except 4 were isolated from P.sibirica L. for the first time.
