title: A new method for express analysis of flavonoid fraction in nephrophite plant extract and prediction of its antioxidant effects.
abstract: A new chromatographic procedure is proposed for rapid (35 min) complete fractionation of flavonoids in plant raw material; the method well discriminates between components with antioxidant activity (rutin, apigenin, quercetin, hesperidin). The method is based on reverse-phase high performance liquid chromatography using ODS-S5CN carrier and linear 10-60% pyridine elution gradient.
