Supercritical Carbon Dioxide Extraction of Essential Oil from Tibetan Medicine Hippophae rhamnoide and Analysis by GCMS
Abstract:ObjectiveTo analyse the ponents of essential oil from Hippophae rhamnoide. MethodsAfter supercritical fluid extraction, the volatile oil was separated by GC
MS and determined by normalization method. ponents from propoils by SFE were separated and identified. The pounds of volatile oil were 9,12Octadecadienoic acid %,9-octadecenoic acid %,hexadecanoic acid %,n-dotriacontanol %, octadecanoic acid %, hexadecenoic acid %, 9octadecenoic acid, methyl ester %, alphaLinolenic acid % etc. ConclusionThere are abundant of unsaturated fatty acid, saturated fatty acid in the essential oil extracted from Hippophae rhamnoide. This research established a good method for further studying medical application and developing of Hippophae rhamnoide.
Key words:Hippophae rhamnoide; Essential oil; Supercritical fluid extraction; GCMS
