STUDY ON CHEMICAL COMPOSITION AND ANTI-BACTERIAL ACTIVITY OF GINGER ESSENTIAL OIL IN PHU THO PROVINCE

Abstract

Ginger essential oil was extracted by steam distillation method. Gas chromatography–mass spectrometry
(GC-MS) analysis revealed 53 consitituents in ginger essential oil, in which the main component was -
zingiberene with 23.93%. Anti-bacterial activity assays were performed on the ginger essential oil using
the agar well method. The results indicated that the ginger essential oil showed anti-bacterial effects
against Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans, especially Candida
albicans anti-bacterial ability equivalent to antibiotic Nystatin.
