BIRCH LEAF, Betulae folium The drug consists of the dried leaves of Betula, pendula, Roth, and Betula, pubescens, Ehrh., family Betulaceae. The leaves have a weak aromatic smell and light bitter taste. They contain about 2% flavone-glycosides as hyperoside and quercitrin and also about 0.5% ascorbic acid. The diuretic and saluretic effect has been verified in animal experiments and may be due to potassium in the leaves. 

Spare time, has developed artistic TLCs in which the main medicinal plants used were Ginkgo biloba, Echinacea purpurea, Hypericum perforatum, Betula folium, Soli-dago virgauria and Chelidonium majus. The CHROMarts obtained have been shown at trade fairs (Interlaken 1995, InCom 1998) and in om own exhibitions (Ansbach 1998 [172], Eckental 1999 [173]). Experts as well as newcomers to TLC have now taken up this art, and the title pages of brochures and scientific jomnals are now being adorned with CHROMarts [174-176].

Betulae folium and Verbasci fios, which contain saponins (betulin, verbascosaponin), with little or no hemolytic activity and Equiseti herba ( equisetonin ) are easily idem tilled on the basis of their flavonoid compounds the relevant chromatograms are reproduced in Chap. 7.
