目的建立麻仁软胶囊指纹图谱。方法采用Diamonsil C18柱(250 mm×4.6 mm,5μm),流动相为甲醇-0.05%磷酸梯度洗脱,检测波长230 nm,柱温30℃,体积流量1.0 mL/min。测定10批麻仁软胶囊,建立指纹图谱。结果指纹图谱各项参数符合标准,22个共有峰及1个共有峰群,进行了主成分分析。结论建立了麻仁软胶囊指纹图谱,该方法可更全面地控制麻仁软胶囊的质量。
Objective To establish the fingerprint of Maren soft capsule. Methods Diamonsil C18 column (250 mm × 4.6 mm, 5 μm) was used. The mobile phase consisted of gradient elution of methanol and 0.05% phosphoric acid. The detection wavelength was 230 nm and the column temperature was 30 ℃. The volume flow rate was 1.0 mL / min. Determination of 10 batches of hemp soft capsules, the establishment of fingerprints. Results The parameters of fingerprints were in accordance with the standard, 22 common peaks and 1 common peak group, and the principal component analysis was performed. Conclusion The fingerprint of Maren soft capsule was established. This method can control the quality of Maren soft capsule more completely.
