中文摘要:

      目的 探讨九蒸九制对黄精性状、显微及有效成分的影响, 并为黄精的炮制工艺提供相关依据。方法 采用九蒸九制法制备酒黄精, 对其性状特征、显微结构、有效成分等质量控制指标进行评定。结果 黄精在六蒸六制后, 其外观已基本符合中药药典规定, 九蒸九制其表面乌黑油润, 颜色均一具光泽, 内黑里透红, 红里透黑, 内部呈蜂窝状, 草酸钙结构断裂, 多糖含量和水溶性成减少, 醇溶性成分增加, 提示黄精经九蒸九制后, 刺激物逐渐减少, 多糖发生水解, 逐渐分解成单糖而味道由酸涩变甜, 无麻舌感。结论 本研究建立九蒸九制黄精性状评分标准, 以期为黄精九蒸九制品质鉴别和质量标准的构建提供依据。

英文摘要:

      Objective To explore the effects of nine steaming and nine processing methods on the characteristics, microstructure, and effective components of Polygonatum sibiricum, and provide relevant basis for the processing technology of Polygonatum sibiricum. Methods Jiuhuangjing was prepared using the nine steaming and nine preparation method, and its characteristics, microstructure, and active ingredients were evaluated as quality control indicators for evaluation. Results After six steaming and six processing, the appearance of Polygonatum sibiricum basically meets the requirements of the Chinese pharmacopoeia. The surface of Polygonatum sibiricum after nine steaming and nine processing was black, oily, and smooth, with a uniform and glossy color. The interior was black with red inside and black inside, with a honeycomb like structure. The structure of calcium oxalate was broken, the content of polysaccharides and the water-soluble components were reduced, and the alcohol soluble components were increased. This suggested that after nine steaming and nine processing, the irritants of Polygonatum sibiricum gradually decrease, the polysaccharides undergo hydrolysis, and gradually decompose into monosaccharides, and the taste changes from sour to sweet without a tingling sensation. Conclusion This experiment establishes a scoring standard for the characteristics of nine steamed and nine processed Polygonatum sibiricum, in order to provide a basis for the quality identification and construction of quality standards for nine steamed and nine processed Polygonatum sibiricum.
