Anti-oxidant properties and polyphenolic profile screening of Vitis vinifera stems and leaves crude extracts grown in Perlis, Malaysia
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...
