Reversed-Phase High-Performance Liquid Chromatography Analysis of Apigenin and its Glucosides in Flowers of Matricaria chamomilla and Chamomile Extracts

Abstract

Quantitative estimation of the flavones apigenin, apigenin-7-glucoside and apigenin-7-acetylglucoside in ligulate florets of Matricaria chamomilla was performed by HPLC using a reverse-phase column and eluting with acetonitrile/water, acetic acid system. These flavonoids were detected at 335 nm. Apigenin and its glucosides were not found in the tubular florets. The method was also applied to the estimation of these flavonoids in chamomile extracts.
