摘要 目的建立反相高效液相色谱法测定不同产地金银花中木犀草苷、绿原酸、隐绿原酸、新绿原酸和异绿原酸A、B、C的方法。方法PhenomenexODSC】。色谱柱(4.6mm×250mm,5μm),以乙腈(A)-0.4%磷酸(B)为流动相,梯度洗脱(0~10rain,5%→9%A;10—30min,9%A;30—60min,9%-30%A;60—80min,30%A),体积流量1.0mL/min,最大吸收波长下检测(木犀草苷在350iqtm,隐绿原酸、绿原酸和新绿原酸在327am,异绿原酸A、B、C在330nm)。结果7种待测成分分离度良好;各成分质量浓度与峰面积在测定范围内均呈良好线性关系(r≥0.9990),木犀草苷、绿原酸、隐绿原酸、新绿原酸和异绿原酸A、B、C的平均回收率(RSD)分别为99.52%(2.56%)、97.93%(2.19%)、96.12%(1.19%)、102.50%(1.63%)、97.57%(1.60%)、97.12%(2.64%)、100.32%(2.89%)。结论该方法简便、准确、重复性好,可用于金银花的质量控制。 ABSTRACT: AIM To establish a RP- HPLC method for simultaneously determining the levels of galuteolin, ehlorogenic acid, cryptochlorogenic acid, neochlorogenic acid, isochlorogenie acid A, B, and C in Lonicerae Ja- ponicae Flos from different habitats. METHODS A Phenomenex ODS Cls column ( 4.6 mm×250mm, 5 μm) was used with the mobile phase consisting of aeetonitrile (A) -0.4% phosphoric acid (B) in gradient elution mode (0-10 min, 5%A-+9%A; 10-30 min, 9%A; 30 -60 min, 9%A--~30%A; 60 -80 rain, 30%A), at the flow rate of 1.0 mL/min. The UV detection wavelength was set at the maximum absorption wavelength, 350 nm for galuteolin, 327 nm for ehlorogenic acid, cryptochlorogenic acid and neochlorogenic acid, 330 nm for isoeh- lorogenic acid A, B, and C. RESULTS Excellent chromatographic separation was achieved with good line arity (r≥0. 999 0) within the studied concerntration ranges. The average recovery rates (RSD) of galuteolin, chloro- genic acid, eryptochlorogenic acid, neoehlorogenic acid, isochlorogenic acid A, B, and C were 99.52% (2.56%), 97.93% (2.19%), 96.12% (1.19%), 102.50% (1.63%), 97.57% (1.60%), 97.12% (2. 64% ) , 100.32% (2. 89% ), respectively. CONCLUSION The method is simple, accurate and reproducible. It can be used for the quality control of Lonicerae Japonicae Flos.
