摘要
为了探究柚皮黄酮的提取工艺,采用超声波辅助乙醇提取法对琯溪蜜柚果皮中的黄酮及柚皮苷进行提取,优化了液料比、提取时间、乙醇体积分数及提取次数。优化得到的柚皮黄酮提取工艺为:液料比(mL∶g)为45∶1,超声提取时间为50 min,乙醇体积分数为70%,提取次数为4次。在此条件下,琯溪蜜柚果皮黄酮提取量为70.69 mg/g,其中柚皮苷的质量分数为64.27%。
In order to explore the process for flavonoids extraction from Guanxi honey pomelo,ultrasound-assisted ethanol extraction was used to extract flavonoids and naringin from Guanxi honey pomelo peel.The extraction liquid to material ratio,extraction time,ethanol concentration and extraction time were optimized.The optimal extraction process was:liquid to material ratio(mL∶g)45∶1,ultrasonic extraction time 50 min,ethanol concentration 70%,and extraction for four times.Under this condition,the extraction yield of flavonoids was 70.69 mg/g,wherein the content of naringin was 64.27%.
