ANTIFUNGAL, ANTIBACTERIAL AND ANTIOXIDANT COMPONENTS OF ETHYL ACETATE EXTRACT OF QUINOA STEM

Abstract

Quinoa (Chenopodium quinoa L.) is a recently introduced pseudocereal crop in Pakistan. In the present study, methanolic extract was partitioned with n-hexane, chloroform and finally with ethyl acetate. The ethyl acetate fraction was subjected to GC-MS analysis for the identification of various antimicrobial and antioxidant constituents. Thirteen compounds were identified through GC-MS analysis of this fraction. Among these, 11 compounds possessed antibacterial, antifungal and/or antioxidant properties as reported in literature. These include naphthalene; tetradecane; hexadecane; pentadecane; cyclohexadecane; 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester; dibutyl phthalate; 1-nonadecene; 1-octadecanol; 9-hexacosene; and 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester.
