目的研究三叉苦的化学成分。方法利用多种柱色谱方法进行分离纯化,根据光谱数据和理化性质进行结构鉴定。结果从三叉苦中分离出2个化合物,分别是赤式-3-(1′,2′,3′-三羟基)异戊基-7-羟基香豆素(Ⅰ)和β-胡萝卜苷(Ⅱ)。结论化合物Ⅰ是新化合物,命名为三叉苦甲素(evodosin A);化合物Ⅱ是首次从该植物中分离得到。

Objective To study the chemical constituents of Evodia lepta.Methods The chemicalconstituents were isolated by chromatographic methods and their structures were elucidated by physico-chemical characteristics and spectral data. Results Two compounds were isolated and their structureswere identified as erythro-3-(1’，2'，3'-trihydroxy) isopentyl-7-hydroxycoumarin(I)and β-daucosterol(Ⅱ).Conclusion Compound I is a new one named evodosin A while compound II is isolated from E.lepta for the first time.
