【摘要】 目的:研究藏药波棱瓜子RP-HPLC指纹图谱,为科学评价及有效控制其质量奠定基础。方法:采用梯度洗脱的方法进行色谱分离,测定了10批不同产地批次的波棱瓜子样品。结果:不同批次产地的波棱瓜子药材指纹图谱相似度较好,10批样品得到的色谱指纹图谱有36个共有峰。结论:采用RP-HPLC方法控制药材的指纹图谱,方法重现性好,用于波棱瓜子的质量评价切实可行。不同产地批次波棱瓜子药材化学组成相似,其相对比例较稳定。更多还原

【Abstract】 AIM: In order to evaluate and effectively control the quality of the Tibetan crude drug Herpetospermum pedunculosum,RP-HPLC fingerprint researches were conducted. METHODS: The gradient elution was applied in chromatographic separation,and 10 batches of samples from different producing areas were tested. RESULTS: Fingerprint chromatograms had a high similarity from different producing areas and batches showing 36 characteristic peaks in common. CONCLUSION: RP-HPLC is a repeatable method of controlling the fingerprint chromatograms,thus is practicable in the quality evaluation of Herpetospermum pedunculosum.Chemical components of samples from different producing areas and batches are similar,and the component ratios are stable.更多还原
