Influence of different processing techniques of massa medicata fermentata on their amylase activity / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To optimize different processing techniques of Massa Medicata Fermentata.</p><p><b>METHOD</b>Single factor test was adopted, with the amylase activity of Massa Medicata Fermentata as the assessment indicator, to observe the influence of such factors as fermentation time and mixture techniques of active pharmaceutical ingredients on the amylase activity of Massa Medicata Fermentata. Meanwhile, Massa Medicata Fermentata prepared with the optimum processing techniques and superior and inferior products of Massa Medicata Fermentata in the market were compared in amylase activity, soluble starch content and soluble polysaccharide content.</p><p><b>RESULT</b>The optimum fermentation time was 7 days. Adzuki bean shall be boiled before mixed with other materials. Artemisia annua, Polygonum hydropiper and Cocklebur grass shall be evenly mixed water decoction. The amylase activity, the soluble starch content and the soluble polysaccharide content of fermented Massa Medicata Fermentata could reach to 49.372 mg x min(-1) x g(-1), 7.967%, and 16.65% respectively, significantly higher than the two types of Massa Medicata Fermentata sold in the market.</p><p><b>CONCLUSION</b>According to the optimum processing techniques, Adzuki beans were smashed and mixed equally with flour and Armeniacae Semen Amarum powder, and then successively added with A. annua, P. hydropiper and C. grass for even mixture. The fermentation time was 7 days.</p>
