摘要
目的建立河北道地药材远志的HPLC-UV指纹图谱,获得对照图谱,并与不同产地远志药材指纹图谱相比较,为有效控制远志质量提供方法。方法采用HPLC—UV法得到了19批远志样品指纹图谱。色谱条件:Waters 1525高效液相色谱仪,C_(18)柱(250 mm×4.6 mm,5μm),乙腈-0.2%甲酸溶液为流动相进行梯度洗脱.检测波长316 nm,体积流量1.0 mL/min,柱温35℃。结果建立了河北省远志药材HPLC-UV指纹图谱共有模式,并对不同产地药材进行了相似度比较。结论本方法操作简便、快速、准确,为远志药材的鉴别和质量的全面控制提供了依据。
Objective To establish HPLC-UV fingerprints of genuine Radix Polygalae from Hebei Province and get the control fingerprint. To compare the fingerprints of genuine Radix Polygalae collected from different habitats with the control fingerprint so as to establish a specific method for the quality control of genuine Radix Polygalae. Methods The fingerprints of 19 batches of genuine Radix Polygalae were Obtained from Waters 1525 pump. The chromatographic procedure was carried out with Diamonsil^TM C18 （250 mm×4.6 mm, 5 μm） as an analytic column and a mixture consisting of acetonitrile and 0. 2% formic acid in gradient as mobile phase. The detection wavelength was 316 nm. The flow rate was 1.0 mL/min. The temperature of column was 35℃. Results The control fingerprint of HPLC-UV was set up. The fingerprints of genuine Radix Polygalae from different habitats were compared. Conclusion The operation of this method is simple, quick, accurate, and could be used for the identification and quality control of genuine Radix Polygalae.
