  • Abstract

    Cornlettes or baby corn is a type of vegetable. It can be easily found in Asian cuisines. Since previous reports indicated that the crude extracts of cornlettes showed some significant antioxidative scavenging properties, this vegetable may contain certain functional bioactive compounds. This study aimed to identify bioactive constituents in the fractional extract of local Malaysian cornlettes. The aqueous-alcoholic extract of cornlettes was fractioned with hexane and ethyl acetate, subsequently. The LC-MS system was used to elucidate different types of functional compounds from the ethyl acetate fraction. Both crude and the fractions were evaluated for total phenolic content and antioxidant activities. The LC-MS analysis of ethyl acetate fraction showed that it contains six phenolic compounds, four carboxylic acids and one for each of alkaloid, amino acid, ethyl ester and adenine. The ethyl acetate fraction exhibited the most significant DPPH radical-scavenging activity and the highest amount of total phenolic compounds. In summary, cornlettes may provide a rich source of phenolic compounds and functional nutrients including essential fatty acids.
