中文摘要: 为了获得更高的金针菇黄酮得率，探讨微波辅助高压法提取金针菇黄酮的最适工艺条件。通过单因素试 验和正交试验，对固液比、微波功率、微波处理时间、高压时间及高压温度对黄酮得率的影响进行研究，并以金针 菇黄酮得率为评价指标，优化提取工艺。试验结果表明，微波辅助高压法提取金针菇黄酮的最优条件是：固液比为 1 ∶ 50（g/mL），微波功率为 640 W，微波处理时间为 5 min，高压温度为 115 ℃，高压时间为 40 min。以上述条件从金针菇 中提取黄酮，得率可至 11.85 %。
Abstract:In order to obtain a higher yield of flavone from Flammulina velutiper， a high pressure microwave-assisted extraction method was developed. The extraction conditions were optimized through the single factor and orthogonal tests. The effects of solid-liquid ratio， microwave power， microwave processing time， high-pressure extraction time and high-pressure extraction temperature on the extr action yield of flavone were investigated. The experimental results showed that the optimal condition was solid-liquid ratio of 1 ∶ 50（g/mL）， microwave power of 640 W， microwave processing time of 5 min， high -pressure extraction temperature of 115 ℃ and high-pressure extraction time of 40 min. Under these conditions， the extraction yield of flavone from Flammuli－ na velutipe was 11.85 %.
