Chromatographic Identification of Some Flavonoids of Matricaria Chamomilla Growing in Iraq

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. Introduction Matricaria chamomilla is well established as ahousehold medicine, the dried flower-head is the usual form of the crud drug. It is used in Europe, Egypt, south Africa and also in Iraq, moreover in many other countries from many objectives, e.g. convulsions in children, diarrhoea, colic and acidity. Isolation of sesquiterpene lactone has been reported e.g. matricin (I) and matricarin (II) from M. chamomilla. Chromatographic Identification of Some Flavonoids of Matricaria ...
