摘 要:目的:研究不同产地山楂叶药材的HPLC指纹图谱并进行比较,同时建立绿原酸、牡荆素葡萄糖苷、牡荆素鼠李糖苷、金丝桃苷和槲皮素的HPLC分析方法。方法:采用Agilent ZORBAX SB-C18色谱柱(4.6 mm×250 mm,5μm);乙腈-0.5%甲酸水溶液梯度洗脱,流速1.0 mL.min-1,检测波长350 nm,柱温30℃。对13批山楂叶药材进行了指纹图谱及含量测定研究,采用中药色谱指纹图谱相似度评价系统(2004A)软件进行分析。结果:绿原酸、牡荆素葡萄糖苷、牡荆素鼠李糖苷、金丝桃苷和槲皮素的线性范围分别为3.75~120,9.69~310,24.69~790,6.25~200,0.31~10 mg.L-1(r分别为0.999 6,0.999 8,0.999 9,0.999 9,0.999 9);平均加样回收率分别为99.2%(RSD 1.7%),100.3%(RSD 1.8%),99.0%(RSD 1.4%),99.8%(RSD 2.1%),100.5%(RSD 1.9%);13批药材的HPLC指纹图谱共标定了15个共有峰,并对其中5个成分进行了含量测定。结论:该分析方法准确可靠,重复性好,为更好地控制山楂叶内在质量提供科学依据。Objective:To study the HPLC fingerprint of hawthorn leaf from different producing areas,establish a method for the analysis of chlorogenic acid,glucosyl-vitexin,vitexin-2″-O-rhamnoside,hyperoside and quercetin.Method: The separation was carried out on an Agilent ZORBAX SB-C18 column(4.6 mm×250 mm,5 μm)with the mixture of acetonitrile and 0.5% formic acid as mobile phase in a gradient elution model(flow rate 1.0 mL·min-1,detection wavelength 350 nm,column temperature 30 ℃).13 groups of hawthorn leaf were analyzed with the developed HPLC fingerprint and determination methods,the data calculation was performed with similarity evaluation system for chromatographic fingerprint of TCM(Version 2004A).Result: The linear range of chlorogenic acid,glucosyl-vitexin,vitexin-2″-O-rhamnoside,hyperoside and quercetin were 3.75-120 mg·L-1(r=0.999 6),9.69-310 mg·L-1(r=0.999 8),24.69-790 mg·L-1(r=0.999 9),6.25-200 mg·L-1(r=0.999 9),0.31-10 mg·L-1(r=0.999 9),respectively.The average recovery rates of chlorogenic acid,glucosyl-vitexin,vitexin-2″-O-rhamnoside,hyperoside and quercetin were 99.2%(RSD 1.7%),100.3%(RSD 1.8%),99.0%(RSD 1.4%),99.8%(RSD 2.1%),100.5%(RSD 1.9%),respectively.In the fingerprint,15 common peaks of hawthorn leaf were confirmed and 5 peaks were determined.Conclusion:This method provides a scientific basis for controlling the quality of hawthorn leaf.
