Abstract:
Objective To analyze and compare the essential oil ofZiziphora clinopodioides Lam. from different regions in Xinjiang by infrared spectroscopy;To provide a reference for its identification and quality control.Methods Characteristic absorption peaks ofZiziphora clinopodioides Lam. essential oil from 18 regions in Xinjiang Uygur autonomous region were identified, compared and analyzed according to peaks’ shapes, positions and intensities by infrared spectroscopy, second derivative infrared spectroscopy and clustering analysis.Results Differences exist in the characteristic absorption peaks according to peaks’ shapes, positions and intensities. And then the samples from 18 regions can be divided into four categories.Conclusion This method was direct, simple, fast and convenient. Combining with clustering analysis, It could provide a reliable evidence for identification and quality control ofZiziphora clinopodioides Lam..
