TITLE:
摘要: 目的:建立炮山甲的高效液相色谱(HPLC)指纹图谱。方法:采用HPLC法。色谱柱为Capcell Pak MgⅡS5 C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为0.8 mL/min,检测波长为275 nm,柱温为30 ℃,进样量为10 μL。以酪氨酸为参照,测定11批药材的HPLC图谱,采用《中药色谱指纹图谱相似度评价系统》(2004 A版)进行共有峰指认和相似度评价。结果:11批炮山甲药材的HPLC图谱有23个共有峰,相似度均>0.90。经验证,11批药材样品HPLC图谱与对照指纹图谱具有较好的一致性。结论:该研究所建HPLC指纹图谱可为炮山甲的鉴别和质量评价提供参考。
ABSTRACT: OBJECTIVE: To establish HPLC fingerprint of stir-baked Manis pentadactyla. METHODS: HPLC method was conducted. The determination was performed on Capcell Pak MgⅡS5 C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution) at the flow rate of 0.8 mL/min. The detection wavelength was set at 275 nm, and column temperature was 30 ℃. The sample size was 10 μL. Using oxyphenylaminopropionic acid as reference, HPLC chromatograms of 11 batches of medicinal materials were determined. TCM Chromatogram Fingerprint Similarity Evaluation System (2004 A edition) was used for common peak identification and similarity evaluation. RESULTS: There were 23 common peaks in 11 batches of stir-baked M. pentadactyla, with similarity>0.90. After validation, HPLC chromatograms of 11 batches of medicinal materials were in good agreement with control fingerprints. CONCLUSIONS: Established HPLC fingerprint can provide reference for the identification and quality evaluation of stir-baked M. pentadactyla.
