莲龙胶囊质量标准的研究

A Study on the Quality Standard for Lianlong Capsules

目的:对莲龙胶囊的质量标准进行研究,为莲龙胶囊的开发奠定基础。方法:用TLC法对制剂中半枝莲、红花龙胆、白芷进行定性鉴别;用高效液相色谱法对野黄芩苷含量进行定量测定。结果:薄层色谱法可鉴别出半枝莲、红花龙胆、白芷,且斑点清晰,分离度好,无阴性干扰;野黄芩苷进样量在0.1295μg^0.5180μg范围内线性关系良好(r=1.0000),平均回收率为101.14%,RSD值为1.10%。结论:所建立的TLC和HPLC方法专属性强、准确度高、重复性好,可用于莲龙胶囊的质量控制。

Objective： To study the quality standard and lay the foundation for the development of Lianlong capsules. Methods： Sophorae Scutellariae Barbatae Herba, Herba Gentianae Rhodanthae, Angelicae Dahuricae Radix were identified by TLC, and the content of scutellarin in Sophorae Scutellariae Barbatae Herba was determined by HPLC. Results：TLC can identify Sophorae Scutellariae Barbatae Herba, Herba Gentianae Rhodanthae, Angelicae Dahuricae Radix. Scutellarin showed a good linear relationship at a range of 0. 1295- 0. 5180μg. The average recovery was 101.14% （ n = 6）, and RSD was 1.10%. Conclusion：The method is simple, accurate and reproducible. It can be used for the quality control of Lianlong pills.
