1. The coriander-seed, which is used as a condiment in fish ham and fish sausage, was submitted to steam distillation, and the distillate was extracted with ether to collect volatile components. These components were fractionated into fatty acids, phenols and terpenes.
2. The terpene portion was refractionated, each fraction was subjected to chroma tostripping, and the presence of ,8-pinene, p-cymene, terpinolene and geraniol was proved.
3. Antibacterial activity of each fraction was tested with Bacillus subtilis, Salmonella enteritidis, Staphylococcus aureus, Pseudomonas aeruginosa, Proteus morganii and Escherichia coli. All the fractions inhibited bacterial growth at dillutions lower than 20-200 times.
