摘　　要：首次从攀枝花苏铁（Ｃｙｃａｓｐａｎｚｈｉｈｕａｅｎｓｉｓ）的茎、雄花、雌花和种子中共分离出７个化合物．经波谱分析和化学方法分别鉴定为：佳味酚β芸香糖苷（１），穗花杉双黄酮（２），罗汗松双黄酮甲（３），５，５″，７，７″，４′，４－六羟基（２′，８″）双黄酮（４），β谷甾醇（５），胡萝卜苷（６）和棕榈酸（７）．From the methanolic extracts of the stems, flowers and seeds of Cycas panzhihuaensis L.Zhou et S.Y. Yang, seven compounds were isolated for the first time and identified as chavicol β rutinoside (1), amentoflavone (2),podocarpusflavone A (3), 5,5″,7,7″,4′,4 hexahydroxy (2′,8″) biflavone (4), β sitosterol (5),daucosterol (6) and palmitic acid (7). Among them,1 and 4 were found for the first time in Cycas. Their structures were established by means of chemical and spectral analyses.
