【摘要】 <正> 杯菊〔(Cyathocline purpurea(Buch-Ham.)O.Ktze)又名(C.lyrata Cass.)〕属菊科杯菊属植物。广佈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-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-hydroquinonedimethyl(ther)(约70％)及异丁酸百里香酯(thymyl iso-butyrate)(约19％),后者更多还原

【Abstract】 This paper presents the 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 quantitatively 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.更多还原
