正交试验法优选大黄醇回流提取工艺
Orthogonal test for the effect of alcohol extracting procedure to total anthraquinone content in Rhubarb
-
摘要: 本文选用正交设计试验,考察了各因素对大黄醇回流所得提取物中总蒽醌含量的影响。结果表明:回流时间对总蒽醌含量有极显着影响,乙醇浓度也有显着影响。大黄醇回流提取工艺以95%乙醇6倍用量,回流提取2次,每次1小时为最佳。Abstract: Concentration of alcohol, reflowing time and amont of alcohol was tested in cluster analysis for alcohol extracting procedure. Experimental results showed that reflowing time and concentration of alcohol were the significant facts to total anthraquinone content with P<0.01 and P<0.05 respectively. The best extracting procedure can be described as:the drug powder is reflowed 2 times, 1 hour each, percolated by 95% alcohol.
