茯苓为常用中药,其粉末由无色不规则团块及末端钝圆的分枝状团块组成,团块内含有菌丝,水很难浸入内部。关于其片型,有关文献如《中国药典》、《全国中药炮制规范》等多规定切厚片或块。在实际应用中,有的茯苓块厚达1cm 以上。而实验发现,茯苓块煎煮1小时后,取出打碎仍有干芯,茯苓厚片煎煮30分钟也不易煎透。因此,有效成分不能充分煎出,从而影响疗效.我们以正交实验法,选取饮片片型、浸泡时间、煎煮时间三个因素,每个因素各选三个水平(表1),以水溶性煎出物含量为标准,探讨茯苓饮片的最佳片型及煎煮条件。
Radon is a commonly used traditional Chinese medicine. Its powder is composed of colorless, irregular lumps and blunt, rounded, branched lumps. The lumps contain hyphae and it is difficult for water to enter the interior. With regard to its film type, relevant documents such as “Chinese Pharmacopoeia” and “National Code for Processing of Chinese Herbal Medicine” and other regulations stipulate thick cut pieces or blocks. In practical applications, some cymbal blocks are more than 1 cm thick. The experiment found that after the simmering block was boiled for 1 hour, the smashed shards still had a dry core, and it was not easy to decoct for 30 minutes by boiling the thick slices. Therefore, the active ingredients can not be fully decocted, thus affecting the efficacy. We use orthogonal experiments to select the three types of decoction tablets, soaking time, boiling time, each factor selected three levels (Table 1), in order to water-soluble The content of frying extract was the standard, and the best tablet shape and decoction conditions were studied.
