Analysis of Chemical Composition of Volatile Oil in Luzhou Flos Lonicerae by GC-MS
Abstract:ObjectiveTo identify the compositions of volatile oil from Luzhou Flos Lonicerae. MethodsThe volatile oil was extracted from Flos Lonicerae through steam distillation method. GC-MS was used for the determination of volatile oil.The relative contents of constituents were determined by area normalization method.Results31 among the 47 separated constituents were identified,which constituted 89.67% of the total amounts,the contents of 23 compounds were over 1%,Linalool was the richest(24.51%). ConclusionThis method is provided with good separative effect.It is excellent to separate and determine the components of volatile oil from Luzhou Flos Lonicerae,and to offer reference value in the development and application study on the volatile oil.
