摘要
采用气相色谱-质谱联用技术(GC-MS)对广东和广西2个产地石胡荽的挥发性成分进行了研究,其主要成分为桃金娘烯醇、反式-乙酸菊花烯酯、乙酸桃金娘烯酯、棕榈酸、麝香草酚。采用本研究提出的“色谱指纹图谱分区”法对2个产地石胡荽的挥发性成分进行分析和比较,把石胡荽总离子流色谱图分为4个区,并用相对保留值α和相对峰面积Sr进行分析比较。结果表明,此法简单、快速、有效,为建立石胡荽的色谱指纹图谱提供了一种新的方法。
The volatile compositions from Centipeda minima of two sources were analyzed by gas chro- matographymass spectrometry（ GC -MS）. The main components were myrtenol, trans-chrysanthenyl acetate, myrtenyl acetate, hexadeeanoic acid and thymol. The volatile compositions of C. minima from the two sources were compared with each other with the chromatographic fingerprinting method of Dividing Sections. The total ion chromatograms were divided into four chromatographic fingerprinting sections and the compounds were compared with the relative retention value （α） and the relative peak area （St）. The results showed that it was a simple, rapid and efficient method, which offered a new way to the establishment of the chromatographic fingerprints for C. minima.
