Cited by 108. In this work, antibacterial activity of finger citron essential oil (FCEO, Citrus medica L. var. sarcodactylis ) and its mechanism against food-borne bacteria were evaluated. A total of 28 components in the oil were identified by gas chromatography-mass spectrometry, in which limonene (45.36%), γ-terpinene (21.23%), and dodecanoic acid (7.52%) were three main components.
