Study on the GC Fingerprint of Volatile Oils in Pine Needles from Pinus Massoniana Lamb

Objective:To establish GC fingerprint of volatile oils in pine needles from pinus massoniana lamb,and compare the difference composition of volatile oils in pine needles gathered from different area.Methods:The fingerprint was adopted By GC,caryopyllene was used as reference material to analyze the volatile oil of 10 bathes pine needles gathered from different area.Results:17common peaks were found on the GC fingerprint,the sum area of common peak is more than 69% of the total peak area.The main components of volatile oils in pine needles from pinus massoniana lamb.are similarly,but the content is quite different.Conclusion:The established fingerprint of pinus massoniana lamb can be applied as the basis of the quality control of pinus massoniana lamb and its preparation.
