景洪哥纳香叶中的苯乙烯内酯类化合物

目的：研究景洪哥纳香叶的抗肿瘤活性苯乙烯内酯类成分。方法：采用硅胶色谱柱分离，理化性质、光谱数据鉴定结构。结果：分离鉴定7个化合物，其中4个为苯乙烯内酯：（＋）-isoaltholactone（1），goniodiol-7-monoacetate（2），leiocarpin A（3），goniodiol（4），另3个为松乔素（pinocembrin，5），胡萝卜苷（daucosterol，6）和豆甾醇（stigmasterol，7）。结论：化合物1-4体外有抗肿瘤活性，化合物1,2、3为首次从该植物分离得到。     

Styryllactones from the rhizomes of Goniothalamus griffithii

Three new styryl-lactones 8-acetylgoniofufurone(1), 7-acetylgonio-pypyrone(3), and 5-acetylgoniopypyrone(4), along with ten known compounds, goniofufurone(2), goniopypyrone(5), goniothalamin, goniothalenol, (+)-isoaltholactone, goniodiol, 7-acetylgoniodiol, goniotriol, 8-acetylgoniotriol, 9-deoxygoniopypyrone were isolated from the rhizomes of Goniothalamus griffithii Hook f. et. Thoms. Their structures were elucidated by IR, MS, NMR spectra and chemical evidence. All compounds showed cytotoxic activities against human cancer cell lines.
