Abstract: The volatile extraction with special smell from the Choushen (Codo- nopsis sp.) in Yunnan was examined by the GC/MS/DS on Finnigan-4510 type. As the result 25 compounds were identified. The methylester of hexadecanoic acid is the richost (45.75%, relatiye) in the volatile components. It is very interesting that the serial isomer and homologous series of aromatic hydrocarbon were found in the plant.

摘要： 臭参(Codonopsis sp．)俗称臭药、云南参、臭党参等，系桔梗科党参属云南特有植物种，种名待分类学家鉴定。其根具有特殊臭味，民间作为廉价滋补佳品，和肉、蛋一起煮食，具有补中益气，生津之功效。同属许多植物如党参(C．pilosula Nannf)、川党参(C．tangshan Oliv.)等的根，均为著名中药，但都没有臭参那种臭味。该植物的化学成分未见报道。为了解臭参植物的药用价值以及同党参、川党参等的相互关系，我们首先对臭参的挥发性臭味化学成分作了气相色谱一质谱法分析，现将结果简要报告如下。
