Abstract:

This experiment adopts high performance liquid chromatography method to simultaneously detect the content of catechins, epicatechins, gallic acid, rutin and quercetin in cosmetics, and provides certain reference for the detection of antioxidant ingredients in plant extracts in cosmetics. Test samples were separated by CAPCELL PAK MG C18 column (4.6 mm×250 mm) and underwent gradient elution. The mobile phase was 0.1% aqueous phosphate solution-methanol, the wavelength of catechins, epicatechins, and gallic acid was 280 nm and that of rutin and quercetin was 360 nm. The column temperature was 30 ℃ with the PDA detector, and the flow rate was 1.0 mL/min. The five compositions are linearly good in the range of 0.594 5-15.403 6 μg/mL, and the r>0.999. The detection limit of this method is 0.025 1-0.128 4 ng/mL. The average recovery rate in the water matrix is 92%-113%, and that in the cream matrix is 90%-110%. This method is easy to operate, and has good stability. Therefore, it is accurate and suitable for simultaneously measuring the content of catechins, epicatechins, gallic acid, rutin and quercetin in cosmetics.

Key words: high performance liquid chromatography, cosmetics, anti-oxidation, dual wavelengths, content determination
