Abstract: 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.
