从弯锥香茶菜Isodonloxothyrsa地上部分首次分得9个化合物, 根据理化性质和光谱数据鉴定为：正三十三烷(tritriacontane,Ⅰ), 正三十四烷酸(tetratriacontanoicacid, Ⅱ), 正二十烷酸(triacontanoicacid, Ⅲ), 正二十七烷酸(heptacosanoicacid, Ⅳ), 乌发醇(uvaol, Ⅴ), β-谷甾醇(Ⅵ), 紫云英甙(astragalin, Ⅶ), 阿福豆甙(afzelin, Ⅷ)和异槲皮素甙(quercetin－3－O－glucoside, Ⅸ)。

Nine compounds were isolated from the aerial parts of Isodun loxothyrsus.By combination of physical constants and spectral analyses ,they were identified as tritriacontane(I),tetratriacontanoic acid(Ⅱ),triacontanoic acid(Ⅲ),heptacosanoic acid(Ⅳ), uvaol(Ⅴ), sitosterol(Ⅵ). astragalin(Ⅶ), afzelin(Ⅷ)and quercetin-3-O-lucoside(Ⅸ).All of them are isolated from the title plant for the first time.
