Free radical scavenging activity of chamomile methanol extracts could be due to their higher content of phenolic components which were chlorogenic acid, Caffeic acid, p-coumaric acid and ferulic acid

compounds can donate hydrogen atoms to DPPH• and
scavenge it. Such explanation was introduced by Lu and Foo (2001).
