摘要:

基于超高效液相色谱-串联质谱(UPLC-MS/MS)建立了可同时测定中药配方牙膏中来自14类中药提取物的21种指标性成分的方法。牙膏样品经80%甲醇超声提取后,以BEH C18为色谱柱,在0.1%甲酸水溶液-乙腈流动相体系下梯度洗脱分离,采用电喷雾正、负离子多反应监测同时对21种指标成分进行定性鉴别,并结合基质匹配外标法进行定量分析。结果表明,21种指标成分在各自质量浓度范围内线性关系良好,相关系数均>0.99;检出限为0.2~4.8 ng/mL,定量限为0.5~14.5 ng/mL;3个不同浓度水平的平均加标回收率为88.3%~121.0%,相对标准偏差为0.9%~12.6% (n=6)。该方法专属、灵敏,分析效率高,可用于中药配方牙膏中21种指标成分的同时测定,为中药配方牙膏中中药提取物的物质基础和功效性研究提供了技术参考,也为牙膏市场的规范和监管提供了技术支撑。

Abstract:

An ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was established to simultaneously determine 21 characteristic components derived from 14 traditional Chinese medicines (TCMs) in TCM formula toothpaste. The toothpaste samples were ultrasonically extracted with 80% methanol. Separation was achieved on a BEH C18 column (100 mm×2.1 mm, 1.7 μm), employing a gradient elution with 0.1% formic acid aqueous solution and acetonitrile as mobile phases. The 21 characteristic components from TCM materials were simultaneously identified using multiple reaction monitoring (MRM) with electrospray ionization in both positive and negative modes. Quantification was carried out by the matrix-matching external standard method. The 21 characteristic components exhibit good linearity between peak areas and concentrations, with correlation coefficients all above 0.99. The limits of detection range from 0.2 ng/mL to 4.8 ng/mL. The limits of quantification range from 0.5 ng/mL to 14.5 ng/mL. The average recoveries at three different spiked levels are between 88.3% and 121.0%. The RSDs range from 0.9% to 12.6% (n=6). The established method was applied to the detection of 38 real samples from commercially available TCM formula toothpaste. The developed method is specific, sensitive, accurate, and highly efficient. It is suitable for simultaneous determination of these 21 characteristic components in TCM formula toothpaste. This work provides a technical reference for investigating the material basis and efficacy of TCM extracts in TCM formula toothpaste, and it offers support for the standardization and regulation of the toothpaste market.
