Dried ligulate flowers of Matricaria chamomilla contain 7-9% glucosides of apigenin and 0.3-0.5% free apigenin. Glucosides were identified as apigenin 7-glucoside and a 1:3 mixture of the 2″- and 6″-acetates, as determined by 13C NMR analysis.

Abstract
Dried ligulate flowers of Matricaria chamomilla contain 7-9% glucosides of apigenin and 0.3-0.5% free apigenin. Glucosides were identified as apigenin 7-glucoside and a 1:3 mixture of the 2″- and 6″-acetates, as determined by 13C NMR analysis.
