为了研究白木香树干的化学成分,该研究采用硅胶柱色谱与Sephadex LH-20凝胶柱色谱进行分离纯化,并运用波谱方法对所分离的化合物进行结构鉴定。从白木香树干正丁醇萃取物中分离鉴定了16个化合物,经波谱解析鉴定为threobuddlenol C(1),thero-ficusesquilignan A(2),erythro-buddlenol C(3),(±)-buddlenol D(4),(-)-杜仲树脂酚(5),(-)-松脂素(6),5’-甲氧基落叶松脂醇(7),erythro-guaiacylglycerol-β-coniferyl ether(8),threo-guaiacylglycerol-β-coniferyl ether(9),herpetin(10),(+)-丁香树脂酚(11),curuilignan(12),刺五加酮(13),松伯醇(14),3,4,5-三甲氧基苯酚(15),雪胆甲素(16),其中化合物1~13为木脂素。化合物1~10,14~16均为首次从白木香中分离得到。
In order to study the chemical constituents of the wood of A. officinalis, the study was isolated and purified by silica gel column chromatography and Sephadex LH-20 gel column chromatography. The structures of the isolated compounds were identified by spectroscopic methods. Sixteen compounds were isolated and identified from the n-butanol extracts of A. officinalis and identified by spectroscopic analysis as threobuddlenol C (1), thero-ficusesquilignan A (2), erythro-buddlenol C (3), (±) -buddlenol D (7), erythro-guaiacylglycerol-β-coniferyl ether (8), (-) - Eucommia resin phenol (5) threo-guaiacylglycerol-beta-coniferyl ether (9), herpetin (10), (+) - clove phenol (11), curuilignan (12) 4,5-trimethoxyphenol (15), and chlorinumin (16), among which compounds 1-13 were lignans. Compounds 1 ~ 10,14 ~ 16 were isolated from the white wood for the first time.
