Abstract

To analyze the constituents of the essential oils from Radix Angelicae Pubescentis planted in a GAP base of the Chinese medica materials, and provide the scientific basis for quality control.The essential oils were extracted by water-steam distillation and separated by GC capillary column chromatography. The components were calculated with normalization method, and were identified by MS detector.229 peaks weredetected, among which 8 compounds have been identified, which made up 78.23% of the total essential oil.In the total essential oils of Radix Angelicae Pubescentis, 3-carene (8.89%), m-cymene (4.99%) and beta-phellandrene (8.35%) as the monoterpenes and its derivatives, and eudesma-4 (14), 11-diene (4.36%), alpha-selinene (1.36%), ledol (1.14%), alpha-bisabolol (6.03%), and 1, 8-dimethyl-4-(1-methylethyl)-spiro[4.5]dec-8-en-7-one (4.37%) as the sesquiterpenes and its derivatives, are main components.
