Orthogonal Experiment in the Optimization of the Decolorization Technology of Houttuynia Cordata Polycose Active Carbon / 中国药房

OBJECTIVE:To optimize the decolorization technology of Houttuynia cordata polycose active carbon.METHODS:The decolorization technology of Houttuynia cordata polycose active carbon was optimized using orthogonal experiment with temperature,pH value,stirring time and the content of active carbon as factors and the content of polycose and the decoloring rate as indexes.RESULTS:The optimal decolorization technology was as follows:temperature:below 20 ℃; pH=4.0;the content of active carbon was 0.4%,and the stirring time was 40 min.CONCLUSION:The decoloration technology is applicable for industrialized production.
