摘要: 目的:运用反相高效液相色谱法同时测定马铃薯中的绿原酸、咖啡酸、对香豆酸和阿魏酸。方法:色谱柱为YMC-C18(250mm×4.6mm,5μm),流动相为甲醇-水-冰醋酸(30:70:1,V/V)等度洗脱,柱温25℃,检测波长327nm。结果:绿原酸、咖啡酸、对香豆酸和阿魏酸在进样质量浓度分别为7.80~1000、0.78~100、0.312~40、0.078~10μg/mL范围内线性关系良好(r值范围0.9968~0.9999),平均回收率为92.38%~101.73%。结论:本法分析快速准确、灵敏度高、重现性好,江西、北京和新疆3个地域的环境条件对马铃薯的酚酸含量有一定的影响。

Abstract: Objective: A reversed-phase high performance liquid chromatographic (RP-HPLC) method was developed to determine the contents of chlorogenic acid, caffeic acid, p-coumaric acid and ferulic acid in potato tuber from Jiangxi, Beijing and Xinjiang. Methods: The contents of phenolic compounds were measured by RP-HPLC using YMC-C18 column (250 mm × 4.6 mm, 5μm) as the sationary phase and CH3OH: H2O: CH3COOH (30:70:1, V/V) as the mobile phase at a flow rate of 1.0 mL/min. Results: A good linear relationship of this method was achieved in the ranges of 7.80-1000μg/mL for chlorogenic acid, 0.78-100μg/mL for caffeic acid, 0.312-40μg/mL for p-coumaric acid and 0.078-10μg/mL for ferulic acid with a correlation coefficient of 0.9968-0.9999. The average recovery rates of this method were 92.38%-101.73%. Conclusion: The developed RP-HPLC method is characteristic of fast determination, accurate results, high sensitivity and good reproducibility. In addition, different growth environments of potato tuber have an important impact on the contents of phenolic acids.
