灵芝醇提取物抗氧化物质提取工艺研究

Extraction Technology Research of Ganoderma Lucidum Antioxidation

本试验以灵芝粉末为试验材料,以不同浓度的乙醇为试验试剂,以羟基自由基的清除率为指标,通过单因素和正交试验的方法,研究了灵芝抗氧化物质的超声波醇提取工艺,并得到了灵芝抗氧化物质醇提取的最佳工艺参数为:乙醇浓度75%,固液比(g:m L)为1:30,在25℃条件下提取20 min。

The experiment used Ganoderma lucidum powders as experimental materials and different concentrations of ethanol for laboratory reagents. The hydroxyl radicals clearance rate as index, through the single factor and orthogonal experiment, studies the ultrasonic extraction technology of Ganoderma lucidum antioxidation,and get the best process parameters as follows： ethanol concentration is 75%, solid-to-liquid ratio （g： ml） is 1：30, temperature is 25 ℃, time is 20 min.
