摘要
甘草是中国最大宗的药材之一,具有益气补中、清热解毒、调和诸药等功效。除了药用价值外,还具有重要的生态及工业价值。随着人工栽培甘草的面积的加大,对种子的需求也不断增加,而甘草种子的质量决定着甘草成品的质量。笔者从种子净度、千粒重、籽粒大小、发芽率、硬实、霉变等几方面考查研究了目前市售甘草种子的质量状况。研究结果表明:不同来源的甘草种子在千粒重、籽粒大小等方面存在显著差异,其中内蒙古、宁夏甘草种子的千粒重和种子直径要显著高于新疆甘草种子。不同来源甘草种子的发芽率、净度、硬实率、霉变率都存在较大的变异范围,大部分甘草种子未经过种子破硬实处理,硬实率较高,种子无包装,无说明。笔者认为中国应当尽快制定甘草种子的质量分级标准及检验标准,以加强甘草种子市场的规范化。
Licorice (Glycyrrhiza Uralensis F.) is one of the Chinese herbs used in the largest scale, with the drug effect of supplementing qi, clearing away heat and toxic material, harmonizing other medicines and so on. In addition, it has important ecological and industrial value. However, due to predatorily digging roots for a long time, the wild licorice resources are facing with exhausting. The cultivated area of licorice is bigger and bigger, good quality seeds are essential to get good quality medicinal materials. We investigated the market seeds from 10 different areas on cleanliness, germination rate, thousand-grain weight, seed diameter, and hard seeds percentage, moldy seeds percentage. The results indicated: The thousand-grain weight, seed diameter of the seeds from Neimenggu province and Ningxia province are significantly greater than that from Xinjiang province. The cleanliness, germination rate, hard seeds percentage and moldy seeds percentage of seeds from different areas are varied in a large range. Without package, declaration, almost all the seeds were not treated to break the dormancy. The quality grading and testing rules of licorice seeds are suggested to be established as soon as possible.
