目的 通过文献、市场及产地调研形成新的防风Saposhnikovia divaricate商品规格等级划分表，根据防风外观性状及与品质相关的内在指标性成分，通过统计学分析，特征图谱比较，探讨新的防风药材商品规格等级划分的科学性和实用性。方法 采集黑龙江、吉林、内蒙古、河北等主产区以及主流药材市场上不同规格等级的防风药材样品，根据新的规格等级的划分表，测定样品的外观性状、浸出物、升麻素、升麻素苷、亥茅酚苷、5-O-甲基维斯阿米醇苷的特征图谱，通过统计分析方法，研究规格等级与外观性状及内在指标性成分的关系。结果 依照外观性状将防风划分为野生、栽培、仿野生防风3个规格有一定科学依据，同时建议增加升麻素的含量指标作为区分野生防风和栽培防风的指标性成分。结论 不同规格的防风药材在外观性状及内在指标上均有显著差异，不同等级的防风药材是否仅以大小作为划分依据还有待讨论。

Objective A new table of standards of commodity classes of Saposhnikovia Radix is formed through literature market and local area survey. To explore the scientific nature and practicability of new standards of commodity classes of Saposhnikovia Radix, according to the appearance and index components related to quality of Saposhnikovia Radix, through statistical analysis and comparison of characteristic spectrum. Methods Samples of different specifications and grades were collected from Northeast China, Inner Mongolia, Hebei, and the other main production areas, mainstream medicine market. Measuring samples appearance, extractum, characteristic spectrum of four chromones and analyzing data and discussing the relationship between standards of commodity classes and the appearance and index components to provide datas and theoretical support for the new table. Results According to appearance character, the standards of commodity classes of Saposhnikovia Radix divided into three specifications of wild, imitates wild, cultivated were science based. At the same time, it is suggested to increase the content of the cimifugin as the index to distinguish between wild and cultivated Saposhnikovia Radix. Conclusion There were significant differences in appearance and index components between different standards of Saposhnikovia Radix. Whether different classes of Saposhnikovia Radix only depend on size remains to be discussed.
