Research Progress on Quality Grading Standards of Chinese Medicinal Material Seedlings

The research on the grading standards of Chinese medicinal material seedlings is the key to the standardization of seed seedlings, the basis for the standardized production of Chinese medicinal materials, and even the important guarantee for the modernization and standardization of Chinese medicine industry. In this paper, according to the different medicinal parts, the medicinal materials were divided into root and rhizome medicinal materials, flower and fruit seed medicinal materials, whole plant and stem and leaf medicinal materials. The research progress on the seedling quality grading standards of the three kinds of medicinal materials in recent years was reviewed, and the research direction of the seedling standards of Chinese medicinal materials in the future was pointed out, in order to promote the research of seedling grading standards of medicinal materials and provide reference for the standardization and application of Chinese medicinal materials.
