    不同产地紫苏叶HPLC指纹图谱研究

    HPLC fingerprint of Perilla frutescens leaves from different habitats.

    • 摘要: 为建立紫苏叶HPLC指纹图谱检测方法,采用HPLC法,以UltimateTM XBC18(46 mm×250 mm,5 μm)为色谱柱,乙腈(A)01%乙酸(B) 为流动相进行线性梯度洗脱,在330 nm 波长下以迷迭香酸为参照物测定了9个不同产地的紫苏叶的指纹图谱,并作相似度比较分析。建立了紫苏叶HPLC 指纹图谱共有模式, 12个共有指纹峰被标定,并对不同产地紫苏叶HPLC指纹图谱进行相似度比较,结果具有明显差异。该方法准确、简单, 能较好地识别不同产地的紫苏叶样品, 可为紫苏的质量评估提供有益的信息。

       

      Abstract: A method for HPLC fingerprint determination of different growing habitats on Perilla frutescens leaves was established using HPLC detection method equipped with UltimateTM XBC18 column (4.6 mm×250 mm, 5 μm). Acetonitrile and water containing 01% acetic acid were used as mobile phase, and rosmarinic acid served as the reference standard. HPLC had gradient elution mode with the detection wavelength of 330 nm and 9 samples collected from different habitats were detected. Data were analyzed by fingerprint similarity evaluation software to compare the samples. The mutual mode of HPLC fingerprints was set up and 12 mutual peaks were indicated. The P. frutescens samples had significant difference in fingerprints. HPLC detection method is accurate and simple. It can easily identify leaf samples of P. frutescens collected from various habitats, and also can provide some useful information for quality evaluation of P. frutescens.
