独活的生药学鉴别

Pharmacognostical Identification of Radix Angelicae Pubescentis

目的:保障药用独活的质量,为临床应用和进一步研发提供鉴别依据。方法:购买市售独活饮片,应用传统方法对药材性状进行鉴定,运用数码显微技术观察粉末特征,采用TLC法对其进行定性鉴别,并应用HPLC法对蛇床子素进行含量测定。结果:经鉴定5种来源的独活均为正品,其中样品5中蛇床子素含量最高。结论:鉴别结果可作为独活生药鉴定、质量控制及进一步开发利用的依据。

Objective： To ensure the quality of official Radix Angelicae Pubescentis and provide an evaluation standard for clinical application and further research and development.Methods：Traditional technology was employed to identify the pieces of Radix Angelicae Pubescentis phurchased from the market as samples;digital microscope was applied to observe their powder properties;TLC method was used to qualitative identification;HPLC was adopted to determine the content of Osthole.Results： Five different specimens were verified as authentic,the content of Osthole in No.5 specimen was the highest.Conclusion： Identification results can serve as the basis for the pharmacognostical evaluation,quality control and scientific research of Radix Angelicae Pubescentis.
