Han, Yingying published the artcileQuantification of the organic acids in hawthorn wine: a comparison of two HPLC methods, Related Products of alcohols-buliding-blocks, the main research area is Hawthorn wine organic acid HPLC; enzymatic method; hawthorn wine; high-performance liquid chromatography methods; organic acids.

Hawthorn wine is rich in anthocyanins, polyphenols, flavonoids and other macromol. substances, which results in difficulty to rapidly determine organic acids in the wine. An enzymic method is accurate but expensive and not able to quantify all of the organic acids simultaneously. Therefore, in this study, two HPLC methods were applied to quantify the organic acids in the wine with the enzymic method as a reference Seven organic acids were found with the enzymic method including citric, succinic, L-malic, acetic, lactic, pyruvic, and fumaric acids, in which citric and succinic acid accounted for more than 80% of the total acids. By an 87H column equipped with DAD (diode array) detector at 215 nm (HPLC method 1), only citric and lactic acids were quantified accurately and the elution period was shortened from 100 min to 20 min by removing the impurity in the sample with a LC-18 SPE(solid-phase extraction) tube. While citric, succinic, L-malic, acetic, pyruvic, and fumaric acids were quantified reliably by a dC18 column equipped with DAD detector at 210 nm (HPLC method 2), with the sample requires only dilution and filtration before injection. It was suggested that HPLC method 2 was an effective method to quantify the organic acids in hawthorn wine. The method provides a choice for accurate quantification of organic acids in hawthorn wine or other drinks, and would be helpful for controlling the quality of hawthorn wine.
