GC-MS Analysis of Volatile Oil from Alpinia officinarum Hance in Two Different Producing Areas
To analyze the chemical constituents of volatile oil of Alpinia officinarum Hance from Hainan and Xuwen in Guangdong Province, the volatile oil was extracted by water distillation method, and the components were separated and identified by GC-MS. Seventy-seven ingredients were identified, and the main components were terpenoids. There were 34 common compounds in samples from the two producing areas. The result showed that the main constituents in A. officinarum from two different producing areas were different.
