GC–MS analysis of fresh rhizome essential oil of Zingiber ofcinale showed the presence of 69 components, accounting for 96.93% of the total oil. The major component was α ‐zingiberene (28.62%) followed by camphene (9.32%), ar ‐curcumene (9.09%) and β ‐phellandrene (7.97%). Analysis of the oleoresin showed the presence of 34 components, accounting for 88.63% of the total oleoresin. The major components were trans ‐6‐shogaol (26.23%), trans ‐10‐shogaol (13.0%), α ‐zingiberene (9.66%) and 10‐gingerdione (6.80%). Moreover, the essential oil was found to be 100% antifungal against Fusarium oxysporum , whereas the oleoresin was 100% antifungal against Aspergillus niger . The latter expressed better antioxidant activity in sunower oil as compared to the essential oil and synthetic antioxidants (BHA and BHT). Copyright © 2004 John Wiley & Sons, Ltd.
