摘要: 目的 建立难溶性药物冰片的细菌内毒素限值及检查方法,并进行方法学考察。方法 根据《中华人民共和国药典》(2025年版)相关要求,确定冰片的细菌内毒素限值;用无水乙醇溶解冰片,再以细菌内毒素检查用水(BET水)稀释,分别采用凝胶法和动态浊度法开展干扰试验和细菌内毒素回收试验。结果 供试品经无水乙醇溶解后,用BET水稀释40倍以上时,对凝胶法和动态浊度法检查无干扰,检查结果符合规定。结论 建立的方法适用于冰片细菌内毒素检查,有助于中药冰片的质量标准提升,也为其他难溶性药物的细菌内毒素检测提供参考。

Abstract: Objective To establish the bacterial endotoxin limit and test method for the insoluble drug—borneol—and to validate the method. Methods The bacterial endotoxin limit for borneol was determined according to the Chinese Pharmacopoeia (2025 Edition). Borneol was dissolved in anhydrous ethanol and diluted with water for the bacterial endotoxin test (BET water). Interference and bacterial endotoxin recovery tests were performed using the gel method and kinetic turbidimetric assay. Results No interference was observed with either method when the sample dissolved in anhydrous ethanol was diluted at a dilution factor of 40 or more with BET water, and the results of each test met the related requirements. Conclusion The established method is applicable to testing of bacterial endotoxins in borneol, which can contribute to the improvement of quality standards for borneol as a traditional Chinese medicine. This study is expected to provide a reference for related tests.
