摘要:

为探究4个采收月份(即2018年的12月和2019年的1月、2月、3月)广西莪术挥发性成分的差异性及动态变化规律,该研究利用气相色谱-质谱联用仪(GC-MS)对挥发性成分进行分析鉴定,并运用化学计量学方法对相对含量在1%以上的挥发性成分进行数据分析。结果表明:经GC-MS分析均鉴定出34种挥发性成分,不同采收月份广西莪术挥发性成分相对含量存在差异性; 主成分聚类分析均分为4类,采用偏最小二乘法判别分析发现7个差异性化合物,其中莪术呋喃二烯酮的含量在1月份达到峰值,吉马酮和humulene 2,3-epoxide两个化合物的相对含量均在2月份达到最高,莪术烯、萜品油烯、异龙脑和表莪术呋喃烯酮在3月份达到峰值。该研究结果为广西莪术的质量控制、生长过程控制以及其他开发研究提供了参考依据。

Abstract:

To explore the difference and dynamic change of volatile components of Curcuma kwangsiensis in four harvest months(i. e. December 2018 and January, February, March 2019), gas chromatography-mass spectrometry(GC-MS)was used to analyze and identify the volatile components, and chemometrics method was used to analyze the volatile components with a relative content above 1%. The results were as follows: A total of 34 volatile components were identified by GC-MS analysis, and the relative contents of volatile components were different in different harvest months; The principal component cluster analysis was divided into four groups, and partial least square discriminant analysis showed that there were seven different compounds, among which the content of furanodienon reached the peak in January, and the relative contents of germacrone, humulene 2,3-epoxide reached the highest in February, while curzerene, terpinolene, isoborneol and epicurzerenone reached the peak in March. This study can provide a reference for quality control, growth process control and other development and research of Curcuma kwangsiensis.
