[Constituents of Asarum europeum L. Communication No. 18. Dynamics of the synthesis of flavonoids].

In the present study, the dynamics of the biogenesis of the flavonoid compounds in haselworth such as isorhamnetin and quercetin glycosides and chalcone diglycoside, respectively, were investigated at various ontogenetic stages. The yield of transisoasarone and chlorophyll a and b were also analysed. The high concentration of transisoasarone was found in the rootstock (rhizome).
