摘要
目的:利用超声波对灵芝菌丝体中灵芝酸的提取工艺进行研究。方法:以单位灵芝菌丝体中灵芝酸的提取量为指标,采用单因素分析和正交实验,对影响灵芝菌丝体中灵芝酸提取的乙醇浓度、超声波浸提时间、浸提pH和料液比四个因素进行研究。结果:乙醇浓度100%,超声波浸提时间90min,pH2·5,加12倍量乙醇浸提为最佳工艺条件,所提取灵芝酸含量达46·7mg·g-1。结论:采用超声波提取技术可以较大幅度提高灵芝酸的提取得率,大大缩短提取时间。
Objective：The extraction process of ganoderma acid from Ganoderma lucidum mycelia by ultrasound was studied.Methods：Unit Ganoderma lucidum mycelia of ganoderma acid as the indicator,using single-factor analysis and orthogonal experiment,the effects of ethanol concentration,ultrasonic extraction time,extraction pH and solid-liquid ratio on ganoderma acid from Ganoderma lucidum mycelia was studied.Results：The optimum extraction conditions were 100% ethanol concentration,ultrasonic extraction time 90min,pH2.5,plus 12 times the amount of ethanol,content of ganoderma acid was up to 46.7mg·g-1.Conclusion：Extraction using ultrasonic technology can greatly improve the extraction yield of Ganoderma lucidum comparing with conventional method,and shorten the extraction time.
