长白山不同区域人参中挥发性、半挥发性成分的研究（英文）

将气流吹扫微注射器萃取(GP-MSE)与气相色谱质谱(GC-MS)联用,建立了一种快速分析长白山人参中挥发性、半挥发性成分的方法.在长白县人参中,共确定了45种化合物(占总组分含量的87%),其中主要化合物有呋喃类(30%)、酸类(30%)和醛酮类(12%).用该方法测定长白山不同区域人参中挥发性、半挥发性成分显示,不同区域人参中挥发性、半挥发性成分的组成相似,但含量有显著差异.研究表明,GP-MSE样品前处理方法对研究植物中挥发性、半挥发性成分有良好的应用前景,有助于植物资源的开发利用.

Study on volatile and semi-volatile compounds of ginseng in different area of Changbai Mountain

A rapid analysis method was established to investigate volatile and semi-volatile compounds in ginseng of Changbai Mountain by gas purge microsyringe extraction （GP-MSE） coupled with gas chromatog-raphy mass spectrometry （GC-MS） technology .The results showed 45 compounds were determined from Fuxing-Xueling ginseng ,accounting for 87% peak area of the total peak area .The major components are fu-rans （30% ） ,acids （30% ） ,aldehydes and ketones （12% ） .The method was applied to compare composition profiles of volatile and semi-volatile compounds of ginseng in different area of Changbai Mountain .Results of ginseng in differenet area of Changbai Mountain showed similar volatile and semi-volatile profile ,but with dif-ferent in amount .The GP-MSE sample preparation method has a well prospect of analyzing volatile and semi-volatile compounds in various plants and will facilitate the exploiting and utilizing precious medicinal plants of Changbai Mountain .
