Abstract
Grape has become a fast growing agricultural sector in Malaysia producing between 0.62 kg to 2.03 kg waste per vinestock. This study aims to generate useful information on anti-oxidative properties as well as polyphenolic composition of grapevine waste. Stems and leaves of Vitis vinifera cultivated in Perlis, Malaysia were extracted using methanol, ethyl acetate and petroleum ether. Ethyl acetate stems extract exhibited highest total phenolic content. While in DPPH assay, methanolic stems extract show the highest antioxidant activities. This result indicates that total phenolic content in the extracts may not contribute directly to the antioxidant activities. Thin Layer Chromatograms of all crude extracts exhibited good separation under solvent system petroleum ether-ethyl acetate (2:3) resulted in detection of resveratrol in ethyl acetate stems crude extract
