The effects of extracts from bean sprout (Glycine max), dropwort (Oenathe javanica) and radish (Raphanus sativus Var. hortensis for. acanthiformis) by solvent separation on alcohol dehydrogenase (ADH) activity in vitro were investigated. The extracts were obtained from alcohol extracts of bean sprout, dropwort and radish, followed by solvent separation. Aqueous fractions facilitated much higher ADH activity than organic fractions. The facilitating rates of bean sprout, dropwort and radish in aqueous fractions were 125.75%, 104.94% and 87.63%, respectively. Basic fractions showed the highest facilitating rate with about 40%. Also other fractions showed below 20% facilitating rate and didn't show great difference from organic fractions. Phenolic fractions didn't show great effect on ADH activity.
