Comparison of Volatile Oils from both Fructus Aurantii and Fructus Aurantii Immaturus of Citrus wilsonii in Shaanxi by GC-MS

Abstract:

The volatile oils origin from both Fructus Aurantii Immaturus(FAI) and Fructus Aurantii(FA) of Citrus wilsonii Tanaka grown in Hanzhong,Shaanxi Province were extracted by steam distillization,and qualitatively and quantitively analyzed by GC-MS in this study.The differences between C.wilsonii and C.aurantium on volatile oils were also compared.The FAI of C.wilsonii were composed of 65 volatile oils,with the main components of D-limonene,γ-terpene,β-cubebene and α-pinene.FA contained 75,with D-limonene,γ-terpene,β-myrcene and α-terpineol as the main components.A total of 44 common constituents existed in both FAI and FA of C.wilsonii.Compared with volatile oils of C.aurantium,those in FAI of C.wilsonii were 8 similar and 57 different,and those in FA share 12 same substrance.Therefore,volatile oils were very similar in both parts of the same species,however,there are different between C.wilsonii and C.aurantium.
