Popis: New, simple, cost effective, accurate and reproducible RP-HPLC method was developed and validated for the quantification of trans-resveratrol in the extracts of grape exocarp and seeds. The method has proved to be simpler and faster than available methods. Methanol was used as a mobile phase with a flow rate of 1.0 cm3 min-1, while the quantification was effected at 306 nm. The separation was performed at 35°C using a C18 column. The results showed that the peak area response was linear in the concentration range of 1-40 μg cm-3. The values of LOD and LOQ were found to be 0.125 and 0.413 μg cm-3, respectively. The antioxidant activity of the extracts was determined using DPPH assay. The ability of DPPH radicals inhibition decreases in the following order: the extract of grape exocarp > trans-resveratrol standard > the extract of grape seeds.
