Comparison of different volatile oil extraction processes from honeysuckle and its component analysis
摘要
Abstract
Volatile oil was extracted from honeysuckle by coeno-water distillation and supercritical CO2 extraction.Comparison between the two processes were analyzed by GC-MS.The optimum distillation extraction conditions were:honeysuckle crushing level of 20 mesh,soak time of 28 h with 5％ salt solution,solid-liquid ratio of 1∶ 10,extraction time of 42 h,the yield of volatile oil is 0.17％,product is yellow waxy solid with heavy taste of wax;The best extraction conditions for supercritical fluid extraction-CO2 were as follows:honeysuckle crushing level of 80 ～ 100 mesh,extraction pressure 45 MPa,temperature 45 ℃,CO2 fulx of 4 L · min-1,0.5 h static extraction and 1 h dynamic extraction.The yield is 2.07％ and the product is light yellow to pale green paste with delicate fragrance.By GC-MS analysis,79 components of distillation extraction product were separated,which accounted for 98.77％ of the total extracts;56 components of supercritical CO2 extraction products were separated,which accounted for 89.81％ of the total extracts.Aroma component of supercritical CO2 liquid extraction product is more than that of coeno-water distillation.By comparison,the supercritical fluid extraction is a better extraction process with maintenance time reducied and high yield and the essential oil has delicate fragrance.关键词
