Analysis of volatile components in forsythia decoction piece and its standard decoction,volatile oil inclusion compounds
Objective To explore the differences of volatile components in forsythia decoction pieces,its standard decoction and volatile oil inclusion compounds.Methods The volatile components in forsythia decoc-tion pieces and its standard decoction and volatile oil inclusion compounds were determined by gas chromatog-raphy-ion migration spectrometry.Results A total of 14 volatile compounds were detected and three were identified,namely α-pinene,limonene and linalool.The volatile components of forsythia decoction pieces and volatile oil of forsythia were basically the same,but different from forsythia extract.The standard decoction of forsythia was consistent with the volatile components in the inclusion compound of forsythia volatile oil.Con-clusion The composition of the inclusion compound of forsythia volatile oil is different from that of forsythia volatile oil,but it is basically the same as that of forsythia standard decoction,which can provide reference for the production and quality control of forsythia formula granules.
