[Seasonal fluctuation of flavonol glycosides in Epimedium species].
The seasonal fluctuation of flavonol glycosides in the leaves of Epimedium grandiflorum var. thunbergianum, E. cremeum and E. sempervirens (Berberidaceae) was investigated. The total content of glycosides was shown in the highest quantity at the flowering time, and as the leaves mature it has become stable amount with a little decrease.
