槐米炭为中医止血要药。槐米所含成分中,其鞣质部分可收敛止血。关于槐米炭炮制工艺与质量问题,据现有报道,认识并不统一。有的认为槐米炒炭后鞣质含量增加,在190～210℃增加最多,超过反而减少;有的认为炒炭温度在150～160℃时鞣质含量最高;还有的认为炒炭后鞣质含量下降。为什么对同一种药材采用相同方法加工炮制后,其内含质量却有如此悬殊差异?为此,我们按药典法炮制加工槐米炭。在此较全面地考察了影响炮制品质量的诸因素基础上,用氧化还原法测定相同炮制标准、不同炮制条件的三种槐米炭中鞣质含量,结果均
Sticky rice charcoal is the medicine to stop bleeding in traditional Chinese medicine. In the ingredients contained in glutinous rice, the enamel part of the glutinous rice can stop bleeding. With regard to the arts and craftsmanship of glutinous rice processing, according to existing reports, the understanding is not uniform. Some believe that the glutinous rice roasted with charcoal content increases, at 190 ~ 210 °C increased the most, more than decreased; some believe that the temperature of charcoal at 150 ~ 160 °C, the highest content of tannins; The quality content decreased. Why is the difference in the quality of the same medicinal material used in the same method used for concocting? For this reason, we use the Pharmacopoeia method to process and process glutinous rice charcoal. After comprehensively examining the factors that affect the quality of processed products, the redox method was used to determine the content of tannin in three kinds of sticky rice charcoal with the same processing standards and different processing conditions.
