The Study on the Composition in Pharmacopunctures of Eight Principles by Gas Chromatography/Mass Spectrometry

Objective: The purpose of this study was to investigate the composition for pharmacopunctures of eight principles hydrodistillation layer. Methods: The study was determined the hydrodistillation layer for pharmacopunctures of eight principles by hydrodistillation method. The effective components in hydrodistillation layer for pharmacopunctures of eight principles were extracted with ethyl ether or dichloromethane, and then analyzed by Gas Chromatography/Mass Spectrometry(GC/MS). Results: 1. Analyzed pharmacopunctures of eight principles by GC/MS, a lot of differences according to extraction solvent by each pharmacopunctures of eight principles and specific peak patterns were seen. 2. The main compound in pharmacopunctures of eight principles was a kind of hexaoxacyclohydrocarbon that has long hydrocarbon chain.
