目的:研究滇桂艾纳香地上部分的化学成分。方法:应用多种色谱技术分离和纯化滇桂艾纳香地上部分的化学成分,采用理化及波谱分析法鉴定其中化合物的结构。结果:从滇桂艾纳香地上部分的乙醇提取物中分离得到13个化合物,分别鉴定为小麦黄素(1)、小麦黄素7-O-β-D-吡喃葡萄糖苷(2)、芹菜素(3)、芹菜素7-O-β-D-吡喃葡萄糖苷(4)、木犀草素(5)、木犀草素7-O-β-D-吡喃葡萄糖苷(6)、6-甲氧基木犀草素7-O-β-D-吡喃葡萄糖苷(7)、原儿茶酸(8)、原儿茶酸甲酯(9)、咖啡酸(10)、咖啡酸甲酯(11)、β-谷甾醇(12)及胡萝卜苷(13)。结论:化合物1～7、9～13为首次从该植物中分离得到。

IM： To study the ehemical constituents of the aerial paris of Blumea riparia. METHODS： The chemical constituents were isolated and purified by several colmnn chromatographic methods. Their structures were elucidated on the basis of chemical and spectral analvsis. RESULTS： Thirteen compounds were isolated from the 95% ethanol extractof the aerial pats of β. riparia. Theh structures were identified as tricin（ 1 ）, tricin 7- O-β-D-glucopyranoside（2）, apigenin（3）, apigenin 7- O-β-D-glucopyranoside（4）, luteolin （5） , luteolin 7- O-β-D-glucopyranoside（6）, nepitrin（7） ,protocateehuic acid （8）, protoeatecfluic acid methyl ester（9）, eaffeic acid（10）, caffeic acid methyl ester（ 11 ）,β-sitosterol（ 12）and daucoslerol （13）, respectively. CONCLUSION： Compounds 1～ 7 and 9 ～ 13 have been isolated from this plant for the first lime.
