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
