Flavonoids from the leaves of some American species of the genus Betula L.
Abstract
On the basis of the qualitative composition of the leaf flavonoids it may be assumed that B. lutea Michx. is an intermediate form between B. lenta L. and B. papyrifera Marsh., whereas the taxa B. neoalascana Sarg. and B. commutata are rather different from B. papyrifera.
