Abstract:
In order to provide scientific basis for quality evaluation of Lepidium meyenii Walp.in Sichuan province,the extracted constituents of essential oil and petroleum ether were analyzed by gas chromatography-mass spectrometry (GC-MS),respectively.The volatile oil and fat soluble components were extracted by the steam distillation and petroleum ether ultrasonic.They were isolated and identified by GC-MS.The structures were identified in combination with database search system of MS.The relative content of every compound was determined by normalization method.The results showed that a total of 22 compounds were identified in volatile oil (98.85％) and 40 compounds were identified in liposoluble constituents (73.99％).There were significant differences of components and relative percentage contents of volatile oil and fat-soluble components.Dodecane,quinoline,3-methoxybenzaldehyde,palmitic acid methyl ester and ethyl linoleate were the same compositions.Comparative analysis was conducted on volatile oil and liposoluble constituents by GC-MS for the first time.The results provided references for herbal resource investigation and quality standard evaluation of Maca.
