摘　　要：目的 :分离鉴定喙果皂帽花茎枝的化学成分。方法 :硅胶和聚酰胺柱色谱分离 ,葡聚糖柱色谱纯化 ,核磁、质谱、紫外、红外光谱及理化常数鉴定结构。结果 :分离鉴定了 3个A环具醛基黄酮类化合物lawinal,unonal,isounonal和 1个氧化阿朴啡类生物碱 7 oxodehydroasimilobine。结论 :均为首次从该属中得到 ,其中A环具醛基黄酮类化合物为首次从番荔枝科中非假鹰爪属中得到 ,且结构类同 ,说明两属有密切的亲缘关系。Objective:To study the chemical components in the stem of Dasymaschalon rostratum .Method:The components were extracted with solvent, separated and purified with chromatographic methods, identified by NMR, MS, UV, IR and physicol chemical constants.Result:Three A ring formylated flavonoids and one oxoaporphinnoid aikaloid were isolated and identified as lawinal, unonal, isounonal and 7 oxodehydroasimilobine.Conclusion:All the four compounds were isolated for the first time from the genus Dasymaschalon .According to all the phytochemistry papers on Annonaceae , A ring formylated flavonoids in this family were isolated from the genus Desmos for the first time. Thus, it is an interesting discovery in chemotaxonomy which reveals the close relationship between the two genera Desmos and Dasymaschalon . [
