摘要
用正交试验法优选白花鬼针草中总黄酮的提取工艺。以总黄酮得率为评价指标,乙醇浓度、液料比、提取时间、提取温度为考察因素,采用正交试验法确定醇提取白花鬼针草中总黄酮的最佳工艺。结果表明最佳提取工艺条件为30倍量50%乙醇,60℃超声30min,且此条件下黄总酮提取率为6.51%。
To study the optimum ethanol extraction process of total flavonoids in Herba Bidentis Pilosa. The extraction of total flavonoids was choosen as the assessment index. Ethanol volumn, solid - to - iquid ratio, extracting time and temperature were the studing factors. The optimum ethanol extraction process was selected with the orthogonal design. Experimental results showed ： the best technological conditions of the experiment was that adding 30 fold of 50% ethanol, ultrasonic temperature of 60℃ extracting for 30min. and under the condition of the extraction rate was 6.51%.
