摘  要:目的:采用反相高效液相色谱切换波长法建立同时测定白蔹中没食子酸、原儿茶醛、儿茶素、白藜芦醇4个成分含量的方法。方法:采用AgilentZorbaxEclipseplus色谱柱(4.6mm×250mm,5μm);流动相为乙腈-0.1%磷酸水溶液,梯度洗脱:流速:1.0mL·min^-1;检测波长:270nm(0—27min),360nm(27.01—36min),306nm(36.01~40min);柱温:30℃。结果:没食子酸、原儿茶醛、儿茶素、白藜芦醇的进样量分别在0.0522~1.044μg(r=0.9993)、0.0548。1.096μg(r=0.9992)、0.4004—8.008μg(r=0.9990)和0.0086—0.172μg(r=0.9993)范围内,与色谱峰峰面积呈良好线性响应;平均回收率分别为100.5%、98.16%、99.60%、99.80%(n=6)。结论:该方法经方法学验证可用于白蔹的质量控制。Objective: To establish a wavelength switching method for simultaneous determination of gallic acid, protocatechuic aldehyde, catechin, and resveratrol in Ampelopsis japonica root. Methods: The Agilent Zorbax Eclipse plus chromatographic column (4.6 mm x 250 mm, 5 μm) was adopted. The mobile phase was acetonitrile (A) - 0. 1% phosphoric acid solution (B) with gradient elution at a flow rate of 1.0 mL · min- 1. The detection wave- length was 270 nm (0 - 27 min, for gallic acid, protocatechuic aldehyde, and catechin), 360 nm ( 27.1 - 36 min) and 306 nm (36.01 -40 min, for resveratrol). The column temperature was 30 ℃. Results: The method achieved a good linearity in the ranges of 0. 0522 - 1. 044 μg (r =0. 9993 ) for gallic acid,0. 0548 - 1. 096 μg (r = 0. 9992 ) for protocatechuic aldehyde ,0. 4004 - 8.008 μg ( r = 0. 9990) for catechin, and 0. 0086 - 0. 172 μg ( r = 0. 9993 ) for resveratrol. The average recoveries of gallic acid, protocatechuic aldehyde, catechin and resveratrol were 100. 5% ,98.16% ,99.60% ,99.80% (n = 6), respectively. Conclusion: This method can be used to control the quality of Ampelopsis japonica root by methodology validation.
