目前对种子类生药的质量鉴定主要靠感官的经验鉴定法,因各人实践经验长短,体会深浅不同,所以质量标准很不统一,对种子类生药的质量控制有一定困难。为了科学地,统一地制定出种子类生药质量标准,我们根据农业种子学的原理,试对种子类生药物理性质进行了“静止角”、“比重”、“千粒重”等物理数据进行测定,以标示它们的质量要求并提供鉴定方法。一、种子类生药静止角的测定一般称谓“种子”是个集合名词,即种子是个群体,这个群体并非是不变的,如含
At present, the quality assessment of seed crude drugs depends mainly on the sensory experience identification method. Due to the length of practical experience of each person and the difference in depth, the quality standards are not uniform, and there are certain difficulties in the quality control of seed crude drugs. In order to scientifically and uniformly formulate seed quality standards for crude drugs, according to the principles of agricultural seed science, we tested the physical properties of seed crude drugs such as the “still angle”, “specific gravity”, and “1000 grain weight” to determine the physical data. Mark their quality requirements and provide identification methods. 1. The determination of the angle of repose of seed crude drugs is commonly referred to as “seed” is a collective noun, that is, seeds are a group, this group is not constant, such as
