多指标综合加权评分研究乌梅炭炮制工艺

Processing technology for Prunus mume carbon by comprehensive weighted of multi-index

目的优选乌梅炭炮制工艺。方法选择温度、翻炒频率、时间3个因素，采用L9（3^4）正交试验设计，以实验小鼠凝血时间、止血时间、水溶性浸出物、醇溶性浸出物为指标，结合成品性状、收得率及直径大小，综合分析优选乌梅炭的炮制工艺。结果乌梅炭优选炮制工艺：235℃，翻炒频率80次／min，炒制7．5min。结论优选的炮制工艺可操作性强，工艺稳定，凝血作用增强，外观符合“表面焦黑色，内部焦黄色”的炒炭存性要求。

Objective To determine the best processing technology of Prunus mume carbon. Methods L9 （3^4） Orthogonal design was used with three factors of processing temperature, stir-fry frequency, and time. The indicators of processing technology of P. mume carbon were the blood coagulation time, hemo-stasis time of mice, the contents of the water-solubility, the extract of alcohol-solubility, combined with product characters, yielding rate, and diameter size to optimize the processing technology of P. mume carbon. Results The optimized processing technology was as following： The processing temperature was 235 ℃, the stir-fry frequency was 80 times/rain, and the processing time was 7.5 min. Conclusion The optimized processing technology is stable and operable, and meets the need to enhance the effect of blood coagulation, the carbonizing process of ＂the superficial burnt black, the internal burnt orange＂.
