摘要:

建立测定葡萄汁饮料中单咖啡酰酒石酸含量的超高效液相色谱法,对方法学进行了验证。结果表明在0.50~50.00μg/mL范围内线性关系良好,方法的批内及批间准确度在97.1%~106.0%,精确度(RSD)小于4.1%,基质加标回收率在101.8%~109.0%。用该法测定了市售葡萄汁饮料中咖啡酰酒石酸的含量,结果准确。

Abstract:

A method was proposed and validated for determination of cafteric acid in grape juice by ultra-performance
liquid chromatography. The results showed that there was good linearity in the range of 0.50–50.00 μg/mL. The interbatch
and intra-batch precision (RSD) were between 97.1% and 106.0%, and the accurate (RSD) was less than 4.1%. The
recoveries of cafteric acid from spiked samples ranged from 101.8% to 109.0%. The described method was successfully used
for determination of cafteric acid in commercial grape juice drinks.

Key words: cafteric acid, grape juice drink, ultra-performance liquid chromatography, method validation
