目的:比较不同产地郁金挥发油的成分在含量和组成上的差异,以期为温郁金建立科学合理的质量评价体系提供依据。方法:通过水蒸汽蒸馏法提取不同产地郁金中挥发油成分,采用GC-MS法分析挥发油成分和含量,以比较不同产地郁金挥发油化学组成的差异,以吉马酮为主要特征成分进行聚类分析。结果:乐清虹桥2号、四川、乐清白石郁金的挥发油含量分别为31.50、25.10、20.00μL·g-1,远高于其他产地的郁金。10个不同产地郁金挥发油共检测出58种成分,通过聚类分析结果可将郁金分为两类,不同产地(瑞安陶山、瑞安马屿、乐清虹桥1号、乐清虹桥2号、乐清白石、永嘉乌牛、磐安、福建仙游)的温郁金及广西产桂郁金为一类,四川产黄丝郁金为一类。结论:不同产地郁金挥发油的成分在含量和化学组成上具有较大差异。
OBJECTIVE: To compare the differences in the content and composition of the volatile oil from the different origins of Turmeric, in order to provide a basis for establishing a scientific and reasonable quality evaluation system. Methods: The constituents of volatile oil in turmeric from different habitats were extracted by steam distillation. The constituents and contents of volatile oil were analyzed by GC-MS. The chemical components of volatile oil from turmeric were compared by different methods. The main components of yam were identified by cluster analysis. Results: The volatile oil contents of Tulipyu No. 2 in Yueqing, Sichuan and Yueqing were 31.50,25.10 and 20.00 μL · g-1, respectively, which were much higher than those in other origins. The results showed that there are 58 components in 10 volatile oil of Tulipa euphorbiae in different areas. According to the result of clustering analysis, tulip can be divided into two types. Tulip is divided into two types by different origin (Taian Ruian, Ruian Mayu, Yueqing Hongqiao No.1, Yueqing Hongqiao No.2, Yueqing Baishi , Yongjia Wuliu, Pan’an, Fujian Xianyou) and Guangxi Guiyu gold as a category, Sichuan silk yellow tulip as a category. Conclusion: The compositions of volatile oil from different origins have great differences in content and chemical composition.
