GC-MS Analysis of Liposoluble Content of Different Levels Lonicerae Japonica Flos in Hebei

Objective: To compare the chemical constituents of the liposoluble content among different levels Lonicerae Japonica Flos in Hebei. Method: The liposoluble constituents were extracted by CO₂ supercritical extraction and the chemical constituents were analyzed by GC-MS. Result: The Lonicerae japonica flos in Hebei was rich in liposoluble content that first-class has 57 varieties, second-class has 48 varieties and the third has 47 varieties. The essential components were hydrocarbons, alcohols, esters, unsaturated fatty acid, alkenes, ketones, aldehydes. The 12 kinds of constituents were same in three samples and of them the content of nonacosane was the highest with 31.345%, 30.642%, 37.64%. Conclusion: There are many differences in liposoluble content among different levels of Lonicerae Japonica Flos.
