我国姜黄属植物的研究——Ⅱ.五种姜黄属药用植物根茎挥发油化学成分的比较

用GC,GC-MS和TLC分析了国产5种姜黄属植物(姜黄,温郁金,莪术,桂莪术和川郁金)根茎挥发油的化学成分。在OV-17柱上分离出30多个色谱峰,鉴定了24种成分,其中4种(柠檬烯,α-松油烯,芳樟醇和丁香烯)以前未见报道。不同姜黄属植物有许多相同成分,但也有很高含量的不同成分,例如川郁金中的桉叶素,莪术中的莪术酮,姜黄中的姜黄酮和芳姜黄酮。因此根据5种挥发油中主要成分的差别,列出了区分姜黄属品种的表。

STUDIES ON CHINESE CURCUMA Ⅱ. COMPARISON OF THE CHEMICAL COMPONENTS OF ESSENTIAL OILS FROM RHIZOME OF FIVE SPECIES MEDICINAL CURCUMA PLANTS

The essential oils from five species of curcuma plants in China, Curcuma longa,C. wenyujin, C. aeruginosa, C, kwangsinensis and C. sp., were analysed by GLC, GLC-MS and TLC.On OV-17 column, more than 30 chromatographic peaks were observed, of which 24 components were identified. Four of these, limonene, α-pinene, linalool and caryophyllene, have not been reported previously.It was found that these different curcuma plants have many similar constituents, but they also contain different components of high content such as cineole in C sp, curzerenone in C. aeruginosa, turmerone and ar-turmerone in C longa etc.According to differences in the main components of the 5 essential oils, a comparative list is given, which makes it easy to differentiate these curcuma species from, their essential oils, this is very useful for systematizing and distingushing these five Chinese drugs.
