目的:修订和提高黑柴胡药材的质量标准。方法:采用生药学研究考察不同黑柴胡药材的横切面显微特征和粉末特征,依据2010年版《中国药典》附录药品标准研究方法对10批黑柴胡药材的水分、总灰分、酸不溶性灰分和浸出物进行检查,并测定活性成分含量。结果:修订了黑柴胡药材的性状特征和显微特征;建立了TLC鉴别黑柴胡的方法;黑柴胡的水分限度≤10.0%,总灰分≤9.0%,酸不溶性灰分≤3.1%,浸出物的含量≥15%,柴胡皂苷a和d的总质量分数≥0.2%。结论:完善了黑柴胡药材的质量标准,可作为该药材的修订内容。
Objective: To amend and improve the quality standards of Radix Bupleurum. Methods: The biomedical research was carried out to investigate the microscopic and powder features of different cross-section of Radix Bupleuri. According to the standard of Pharmacopoeia of the Chinese Pharmacopoeia 2010 edition, the water, total ash, acid-insoluble ash And extracts were examined, and the content of the active ingredient was determined. Results: The traits and the microscopic characteristics of Herba Bupleurum were revised. The TLC method was used to identify the Bupleurum chinense L.. The water content was less than 10.0%, the total ash content was less than 9.0%, the acid-insoluble ash content was less than 3.1% The content of the substance is ≥15%, the total mass fraction of saikosaponin a and d is ≥0.2%. Conclusion: Perfecting the quality standard of Radix Bupleurum can be used as the revision content of this medicine.
