摘要
利用微波法对黄连中的黄连素进行提取研究,以提取率为评价指标,考察了硫酸浓度、辐射时间、辐射功率、料液体积比等不同条件对黄连素提取率的影响,并与其他方法做了比较,结果表明提取的最优条件为:辐射时间4min,硫酸浓度0.06mol/L,辐射功率中火,料液比1:80,所得最佳提取率为45.9%。对比现有的传统方法可知,微波法省时、易操作,黄连素的提取率可提高35%左右。
Using microwave method to extract berberine in coptis chinensis, extraction rate as the evaluation index, examines sulfuric acid concentration,the radiation time, radiation power, solid- liquid ratio to the influence of different conditions on berberine extraction rate, and has made the comparison with other methods. The results show the optimum conditions for extraction： radiation time 4rain, sulfuric acid concentration 0.06mol/L, the radiation power of fire, and solid - liquid ratio 1 ： 80. The optimum extraction rate was 45.9%. Compared to the existing traditional method, microwave method is time - saving, easy to operate, and the extraction rate of berberine can increase about 35%.
