摘要:

采用高效液相色谱(HPLC)法,建立了石硖龙眼的HPLC 指纹图谱。色谱条件为:Nucleosil C18 反相柱(250mm × 4mm,5μm),流动相为0.01mol/L 的KH2PO4 和甲醇,二元梯度洗脱,流速0.8ml/min,检测波长260nm,柱温4℃。结果表明:14 批次的石硖龙眼水溶性提取物色谱图共有峰13 个。经“中药指纹图谱鉴别分析系统”统计分析,共有峰相对保留时间的相对标准偏差在1.2% 以下,相似度均在0.967 以上。符合指纹图谱的要求,可建立共有模式,作为科学评价石硖龙眼产品质量的检测方法。

Abstract:

In this study, HPLC analysis on Shixia longan (Dimocarpus longan Lour. cv. Shixia) was performed on reversedphase Nucleosil C18 column (250 mm × 4.0 mm, 5 μm) by using mobile phase 0.01 mol/L KH2PO4 and CH3OH, dual gradient elution was proceeded with the flow rate of 0.8 ml/min, and operation conditions were set as follows: detection at 260 nm and column temperature 40 ℃. Results showed that there are 13 common peaks in HPLC chromatogram of water-soluble components of 14 Shixia longan samples collected from different areas. Moreover, by calculated with fingerprint analysis system of Chinese medicine, relative standard deviations (RSD) of relative retained time of common peaks are below 1.2% and their similarity is above 0.967. Therefore, the established chromatographic fingerprint is proved to be a scientific quality evaluation method for Shixia longan.
