Abstract

Brassica rapa L. (turnip) roots were extracted with 70% ethanol, and then sequentially fractionated into n-hexane, chloroform, and ethyl acetate fractions. The ethanol extract possessed antioxidant potentials such as free radical scavenging, nitrite scavenging, and lipid peroxidation inhibitory activities as well as reducing power. Among solvent fractions of turnip roots extract, ethyl acetate fraction exhibited significantly high activities in free radical scavenging (p < 0.05), reducing power (p < 0.001), and lipid peroxidation inhibition (p < 0.05) due to the highest level of total phenolic content. The antioxidant potential showed a positive correlation with total phenolic content.

 

Key words: Brassica rapa L., ethanol extract, antioxidant potential, total phenolic content.
