effect of Clausena lansium, we continued to separate the n-butanol and the water extracts from the stems of C. lansium in order to find the leading compounds with significant activity. Two new phenolic glycosides, Clausenolside A-B (1-2), one new pair of phenolic enantiomers (3a, 3b), and two new monoterpenoids, clausenapene A-B (4-5), together with twelve known analogues (6-17) were isolated from the stems
鉴于黄皮具有显着的神经保护作用,我们继续从黄皮茎中分离正丁醇和水提取物,以寻找具有显着活性的先导化合物。分离出两种新的酚苷,Clausenolside AB (1-2),一对新的酚类对映体 (3a, 3b),和两种新的单萜类化合物,clavenapene AB (4-5),以及 12 种已知的类似物 (6-17)来自C. lanium 的茎。化合物1-17为首次从C. lanium中分离得到。化合物3a、3b、4、16和17对抑制冈田酸诱导的PC12细胞损伤表现出强或中度的潜在神经保护作用,化合物9表现出很强的潜在保肝活性。它们的结构在光谱分析的基础上得到了阐明,包括紫外、红外、核磁共振实验和电子圆二色性(ECD)光谱。
