Chromatographic identification of some flavonoids of matricaria chamomilla growing in Iraq

Abstract EN

Ethanolic extract of the flower-head of matricaria chamomilla which growing in Iraq showed the presence at last of two new flavonoids quercetin (III) and isorhamnetin (IV), which gave a bright yellow colour during TLC separating under U.V light.

These compounds were investigated on the basis of the comparison of their Rf-values in tables and using quercetin as authentic sample for comparison.
