从臭灵丹(LaggeraPterodonta(DC)Benth)地上部分水煎浓缩液的氯仿提取液中,分离出四个化合物(1-4),1和2为倍半萜化合物,3和4为黄酮化合物,经紫外光谱、红外光谱、核磁共振^1H谱、^1^3C谱、^1H-^1Hcosy谱及质谱测定,分别为臭灵丹酮酸、冬青酸、洋艾素和金腰素乙。化合物1具有桉烷型倍半萜结构,为Δ^4^,^1^1-桉双烯-3-酮-13-酸,它是一新化合物。

From the chloroform extract of decoctum of Laggera Pterodonta (DC) Benth (Compositae) aried part, Compound 1-4 were obtained after colum chromatography on silical gel and crystallization. 1 is a new compound which has sesquiterpene skeleton of eudesmane based on ^1^3C NMR, ^1H-^1H cosy and mass spectral data. It has the structure of Δ ^4^,^1^1-eudesm-dien-3-one-13-oic acid. 2-4 were elucidated as the known ilicic acid, artemitin and chrysospeneti B respectively based on the spectroscopic data and comparision with the literature.
