Flavonols are one of the most studied classes of polyphenolic phytochemicals because of the importance pertaining to their antioxidant potency and other biological activities. In order to characterize the grape cultivars in Korea, flavonols present in the leaves of 30 grapes were screened using HPLC. A total of 19 flavonols (six isorhamnetin derivatives, seven kaempferol derivatives and six quercetin derivatives) were separated and identified with HPLC and related techniques. Among them, the most abundant flavonol was quercetin 3-O-glucoside 7-O-glucuronide. These results suggest that the different kinds of flavonols are present among various grape species or cultivars. In the future research, the availability of abandoned grape leaves in the vineyards will be focused as potentially valuable resources on medicinal areas.
