Abstract:
The purpose of this paper is to report on the comparative pharmacognostical research on epicarp, mesocarp, and seeds of grapes Hamburg cultivar.
Microscopically we identified the following specific histologic elements: cells with moniliform walls, oil and epicarp with a smooth cuticle. The chemical analysis has shown the presence of procyanidins, anthocyanins, flavonoids, hydroxycinnamic acid derivatives, triterpenes, sterols, tannins, polysaccharides, monosaccharides and non-alkaloid nitrogen containing compounds. The grapes of Hamburg cultivar have a higher percent of total hydroxycinnamic acid derivatives in seeds, and a higher percent of procyanidins in epicarp.
