【摘要】 以花椒籽核为原料,研究了超声波提取花椒油的工艺条件,考查了提取介质、温度、时间和液固比对花椒油提取率的影响。实验结果表明:用体积分数95%乙醇为提取介质,在液固比为3∶1(mL∶g)、60℃温度下超声提取90 min,花椒油的提取率可达7.8%,比加热提取法高48.9%。花椒油经气相色谱-质谱联用仪分析,鉴定出16种成分,其中有9种为烯烃化合物。更多还原

【Abstract】 The conditions for ultrasonic extracting oil from Zanthorylum bungeanum seeds were studied.The effects of extract medium,temperature,time and ratio of liquid to solid on extraction yield of zanthorylum bungeanum oil were investigated.The experimental results showed that using 95% ethanol as extract medium,ratio of liquid to solid(ratio of volume to mass for both) at 3∶1,extracting at 60℃,90 min,can obtained 7.8% of Zanthorylum bungeanum oil,which was 48.9% higher than that of heating extraction.Sixteen substances in Zanthorylum bungeanum oil were authenticated by GC-MS,among them nine substances were olefin hydrocarbon compounds.更多还原
