摘 要 ：杯菊[(Cyathocline purpurea(Buch－Ham.)O．Ktze)又名(C．lyrata Cass.)]属菊科杯菊属植物.广怖于热带亚洲和热带非洲，在我国南方的广西、贵州、云南均有野生分布.我国民间用于杀虫、清热解毒、消炎止血、除湿利尿等,在一些地方性的本草图册中均有记载.印度学者对印度索加尔产的杯菊精油化学成份进行过研究,其主要成份为倍半萜醇一杯菊醇(cyathoclol)及其乙酯,约占精油的50%.本文报道云南南部产杯菊的精油化学成份,其主要成份为百里香氢醌二甲醚(thymo-hydroquinone dimethyl ether)(约70%)及异丁酸百里香酯(thymyl iso－butyrate)(约19%)，后者为首次从植物中分离到。证明化学成份与印度学者的分析结果全然不同。这说明一个广布的植物种，由于地理环境及生态条件的差异，其化学成分，特别是精油成分差别甚大。

Abstract:This paper presents thc chemical constituents of the essential oil of Cyatho- cline purpurea (Buch.-Ham.) O.Ktze., which is a folk drug and widely used as antiphlogistic, styptic, insecticide, diuretic etc. in China. Twenty two compounds were qualitatively and quentitatively analysed from this essential oil on the basis of GC/MS/DS, showed in Table (1 ). Two of them were important components: thymohydroquinone dimethyl ether (I ) (ca. 70%), and thymyl iso-butyrate (II) (ca. 19%), which were separated by chromotography and determined by the data of IR, PMR, CMR and MS. The thymyl iso-butyrate was first isolated from plant.
