摘要: 为探究黄柏配方颗粒抑菌活性的中和方式,为具抑菌活性中药配方颗粒的质量控制和药品标准的完善提供理论和数据支持,采用两类方法(平皿法和薄膜过滤法)、两类中和剂(“3%聚山梨酯80 + 0.3%卵磷脂”和10%羟丙基-β-环糊精)及三个稀释级(1:10、1:100和1:500)的不同组合,测试每种组合中5种试验菌株的加菌回收比值。结果表明,在较低稀释级1:10和1:100,加入两类中和剂的平皿法和薄膜过滤法均无法使金黄色葡萄球菌和白色念珠菌的加菌回收比值满足要求;在1:500稀释级,平皿法中3%聚山梨酯80和0.3%卵磷脂无法完全中和黄柏配方颗粒中抑菌成分对白色念珠菌的抑菌性,需结合薄膜过滤法才可满足回收比值范围(0.5~2.0);使用羟丙基-β-环糊精时,平皿法(1:500)可满足要求。本文建立的黄柏配方颗粒的微生物检查方法,方法稳定、可靠,为药品标准完善提供了数据支持;两种中和剂的效果为抑菌性中药配方颗粒抑菌性的中和提供了参考。

Abstract: To explore neutralization methods for antibacterial activity of Phellodendri chinensiscortex Chinese medicine formula granules (CMFG) as well as to provide theoretical and data support for the quality control of antibacterial CMFG and the improvement of pharmaceutical standards, different approaches were used to eliminate the antibacterial activity ofP. chinensiscortex CMFG. Two microbial enumeration methods (plate-count, PC, and membrane filtration, MF), two neutralizers (a combination of 3% polysorbate 80 and 0.3% lecithin, and 10% hydroxypropyl-β-cyclodextrin, HP-β-CD), and three dilution levels (1:10, 1:100, and 1:500) were used in this study. Recovery ratios of five test strains were measured for each combination. Results revealed that at lower dilution levels of 1:10 and 1:100, neither PC nor MF methods with either neutralizers could achieve acceptable inoculum recovery ratios (0.5~2.0) forStaphylococcus aureusandCandida albicans. At higher dilution level of 1:500, 3% polysorbate 80 and 0.3% lecithin combined with the PC method could not completely neutralize the antibacterial components inP. chinensiscortex CMF againstC. albicans, and only when combined with the MF method could the recovery ratio meet the required range (0.5~2.0). Conversely, HP-β-CD at the dilution level of 1:500 achieved satisfactory recovery ratios (0.5~2.0) for all five strains when the PC method was used. Accordingly, a microbial examination method for P. chinensiscortex CMFG compliant with theChinese Pharmacopoeia2025 was established. This method has been validated as stable and reliable, providing robust data support for refining its quality standards. Moreover, the effectiveness of the two neutralizers provides a practical reference for neutralizing the antibacterial activity of traditional CMFG with inherent antibacterial properties.
