摘要: 本文报道了对山楝Aphanamixis polystachya枝叶的化学成分进行研究。采用硅胶柱色谱、Sephadex LH-20、RP-C18、HPLC等色谱分离手段,从其95%乙醇提取物中分离得到9个化合物,通过波谱方法进行鉴定为polystachyadione A(1)、polystachyadione B(2)、labd-13(E)-ene-8α,15-diol(3)、labd-13(E)-ene-8α,15-yl acetate(4)、1S,4S,5S,10R-4,10-愈创木二醇(5)、齐墩果酸(6)、3,4-二羟基苯甲酸(7)、反式咖啡酸(8)和单棕榈酸甘油酯(9)。其中化合物1和2为两个新化合物,化合物4、7、8和9为首次从该植物中分离得到。化合物1、2对脂多糖诱导的RAW 264.7细胞NO生成没有表现出明显的抑制作用。

Abstract:

To investigate the chemical constituents of the branches and leaves of Aphanamixis polystachya.Nine compounds were isolated from the 95% ethanol extract of A. polystachya by various column chromatography involving silica gel,Sephadex LH-20 gel,RP-C18and HPLC.Their structures were identified by chemical properties and spectroscopic analyses,and were elucidated as polystachyadione A (1),polystachyadione B (2),labd-13(E)-ene-8α,15-diol (3),labd-13(E)-ene-8α,15-yl acetate(4),1S,4S,5S,10R-4,10-guaianediol (5),oleanolic acid (6),3,4-dihydroxybenzoic acid (7),caffeic acid (8) and α-monopalmitin (9),of which compounds 1 and 2 are new.Compounds 4,7,8 and 9 are obtained from this plant for the first time.The activity tests showed that compounds 1 and 2 have no significant inhibition against NO production.
