| مستخلص: | Sa saznanjem važnosti katehina i mogućnosti njihove primjene u farmakologiji, te važnosti polifenola u kemotaksonomiji biljaka istraživali smo sadržaj katehina (flavan 3-ol monomera) u sjemenkama grožđa autohtone sorte plavac mali. Metodom rada obavljena je uspješna separacija katehina ekstrahiranih iz sjemenki grožđa. Sorta plavac mali sadrži visoke koncentracije flavan 3-ol monomera. Tijekom dozrijevanja grožđa sadržaj (+) katehina i (-) epikatehina se mijenja. Najveće se promjene zbivaju u vremenu šarka. Using HPLC technique on reversed-phase, the amounts of (+) - catechin and (-) epicatechin in grape seeds of autochthonous Dalmatian cultivar plavac mali, were analyzed during the growth season. To prevent interference between phenolic compounds, because many of them have similar UV absorption spectra, we fractionated acidic and neutral phenolic compounds on Sep Pak C 18 cartridges. Catechins were separated using HPLC with gradient solvent system at 280 mm. The grape seeds were analyzed during various stages of ripening. The results show the highest concentrations of catechins in the verison. The level decrease quickl troughout maturation. The major flavan- 3-ol monomer was (+) - catechin. |
