摘　　要：本文对顶羽菊植物化学成分进行了研究,从中分离出9种化合物,用红外、紫外、核磁共振和质谱分析以及化学反应鉴定了结构,它们是二十九碳烷(Ⅰ)、二十二烷醇(Ⅱ)、豆甾烷醇(Ⅲ)、β-谷甾醇(Ⅳ)、豆甾-7-烯-3-醇(Ⅴ)、三十四碳酸(Ⅵ)、2,4-二(邻甲基偶氮苯)-萘酚-1(Ⅶ)、β-谷甾醇-β-D-葡萄糖甙(Ⅷ)、洋芹素-5-β-D-葡萄糖甙(Ⅸ),其中化合物Ⅶ是首次从天然界获得。Nine compounds were isolated from the plant of Centaurea repens. By means of IR, UV, NMR, MS analysis and chemical reactions, the structure of nine compounds were elucidated as I : n-Nonacosane; Ⅱ : 1-Docosanol; Ⅲ : 3-Stigmastanol; Ⅳ : β-Sitosterol; Ⅴ: Stigmast-7-en-3-ol; Ⅵ: Tetratriacontanoic acid ( β: 2, 4-bis(o-tolylazo)naphth-l-ol; Ⅶ: β-sitosterol-3-β-D-glucoside and Ⅷ: Apigenin-5-oβ-D-glucoside. Ⅶ was isolated for the first time from the natural product. Its spectral data were analyzed in detail. The structure ofⅦ was also proved by chemical synthesis.
