Scope

Main technical content: This document specifies the high-performance liquid chromatography method for determining the content of hydroxybenzoic acid substances in wine. This document is applicable to the determination of hydroxybenzoic acid substances in wine, including gallic acid, catechins, gentisic acid, vanillic acid, syringic acid, methyl catechins, methyl vanillate, ethyl hydroxybenzoate, and ethyl vanillate. The method's detection limits in this document are as follows: the detection limit for gallic acid is 0.0580 mg/L, the detection limits for catechins and syringic acid are both 0.0492 mg/L, the detection limits for gentisic acid and ethyl hydroxybenzoate are both 0.0530 mg/L, and the detection limit for vanillic acid is 0.0720 mg/L. The detection limits for methyl catechins, methyl vanillate, and ethyl vanillate are all 0.0250 mg/L.
