[Analysis of the constituents of volatile oil from Fructus Auranti Immaturus by GC-MS].

To analysis the constituents of volatile oil from Fructus Auranti Immaturus by GC-MS. The volatile oil was extracted by steam distillation, then separated by capillary gas chromatography. The constituents of volatile oil were identified and their amount were determined by normalization method. Nineteen components were identified from Fructus Auranti Immaturus and their amount accounted 95.791% of total volatile oil. The main components were Limonene (68.25%), gamma-Terpinene (13.02%), alpha-Terpinol (3.28%), beta-Cymene (3.09%), beta-Myrcene (2.34%), alpha-Pinene (1.53%), beta-Pinene (1.05%). The main component of volatile oil from Fructus Auranti is Limonene.
