TITLE:
摘要: 目的:建立三百棒药材的高效液相色谱(HPLC)指纹图谱。方法:采用HPLC法,色谱柱为SinoChrom ODS-BP,流动相为乙腈-0.75%冰醋酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为275 nm,柱温为30 ℃,进样量为10 μL。以岩白菜素为参照,绘制10批药材样品的HPLC图谱,采用《中药色谱指纹图谱相似度评价系统(2004 A)》进行相似度评价,确定共有峰。结果:10批药材样品的HPLC图谱有14个共有峰,其中4批药材样品的相似度均大于0.90。结论:所建HPLC指纹图谱可为三百棒药材的质量控制提供依据。
ABSTRACT: OBJECTIVE: To establish HPLC fingerprint of Tujia medicine Toddalia asiatica. METHODS: HPLC method was adopted. The determination was performed on SinoChrom ODS-BP with mobile phase consisted of acetonitrile-0.75% glacial acetic acid solution (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was 275 nm, and column temperature was 30 ℃. The sample size was 10 μL. Using bergenin as reference, HPLC chromatograms of 10 batches of samples were determined. Similarity evaluation was performed by using Similarity Evaluation System for Fingerprint Chromatogram of TCM (2004 A). RESULTS: There were 14 common peaks in HPLC chromatograms of 10 batches of samples, and the similarity of 4 batches of samples was higher than 0.90. CONCLUSIONS: Established fingerprint can provide reference for the quality control of T. asiatica.
