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.
