Abstract
A new 7-methoxy-2-benzoxazolinone dimer named zeaoxazolinone (2), together with four known compounds; 9-Z-hexadecenoic acid (1), 6-methoxy-benzoxazolinone (3), gallic acid (4), and β-sitosterol-3-O-β-d-glucopyranoside (5) were isolated from Zea mays L. roots. The structural elucidation of isolated metabolites was established on the basis of UV, IR, 1D, 2D NMR, and MS spectral analyses. Compound 2 exhibited a potent antifungal activity against Aspergillus flavus, Fusarium oxysporum, and Candida albicans.
