| 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-C 18 and 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),1 S,4 S,5 S,10 R-4,10-guaianediol(5),oleanolic acid(6),3,4-dihydroxybenzoic acid(7),caffeic acid(8)andα-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. |
