Abstract
Hydrolyzed alcoholic extracts of Viscum album L. were analyzed by HPLC for their flavonoid content. Besides the known flavonoid aglyca 4′,5,7-trihydroxy-3′- methoxyflavanone (homoeriodictyol), 5,7-dimethoxy-4′- hydroxyflavanone, 3′-methylquercetin (isorhamnetin) and 3′,7-dimethylquercetin (rhamnazin) another flavanone derivate, 4′,5-dihydroxy-7-methoxyflavanone (sakuranetin) was detected in mistletoe extracts for the first time. With the described method it is possible to distinguish the three mistletoe subspecies abietis, album and austriacum.
