摘要: 目的:建立蟾皮药材的质量控制方法研究。方法:根据蟾皮样品的性状特点,制定蟾皮的性状特征;采用干蟾皮对照药材、华蟾酥毒基进行薄层色谱鉴别;采用乙醇为溶剂,制定热浸法浸出物的限度;以高效液相色谱法测定蟾皮中华蟾酥毒基与脂蟾毒配基的含量,流动相为0.5%磷酸二氢钾溶液-乙腈(50∶50)(采用磷酸调pH为3.2);柱温40 ℃;色谱柱为Sepax BR C18(4.6 mm×250 mm,5 μm);紫外波长设定为296 nm。结果:性状制定合理,能够描述蟾皮的性状特征。薄层色谱鉴别荧光斑点清晰,稳定性好,专属性强。华蟾酥毒基与脂蟾毒配基分别在5.69~591.50、5.44~504.39 μg·mL-1的范围内,线性关系良好r≥0.999 7,平均回收率≥97.3%,RSD≤1.06%。结论:本研究建立的蟾皮定性与定量的质量控制方法简便、方法学可靠,为蟾皮的质量评价提供拓展思路。

Abstract: Objective: Establish a quality control research method for Bufonis corium. Methods: Based on the characteristics of Bufonis corium samples, formulate the characteristics of Bufonis corium. Thin layer chromatography identification was performed using Bufonis corium as a reference medicinal material and Cinobufagin. Using ethanol as the solvent, establish limits for the extract of hot leaching method. The content of cinobufagin and resibufogenin was determined by high-performance liquid chromatography, with a mobile phase of 0.5% potassium dihydrogen phosphate solution acetonitrile (50∶50) (adjusted to pH 3.2 with phosphoric acid). Column temperature 40 ℃. The chromatographic column is Sepax BR C18 (4.6 mm×250 mm, 5 μm). The UV wavelength was set to 296 nm. Results: The results showed that the characterization was reasonable and could describe the characteristics of Bufonis corium. Thin layer chromatography has clear fluorescent spots for identification, good stability, and strong specificity. The linear relationship between cinobufagin and resibufogenin is good within the range of 5.69-591.50 and 5.44-504.39 μg·mL-1, respectively, with a correlation coefficient of r≥0.999 7 and an average recovery rate of ≥97.3%, RSD≤1.06%. Conclusion: The qualitative and quantitative quality control methods established in this study for toad skin are simple and methodologically sound, providing expanded ideas for the quality evaluation of Bufonis corium.
