Gas chromatographic investigation of volatile nitrogen containing bases of Antarctic krill Euphausia superba Dana.
The composition of the volatile nitrogen-containing bases of fresh-caught Antarctic krill E. superba has been investigated by gas chromatography. The analysis was carried out on three packed columns with Apiezon L, Triton X-305, PEG-1000 and one glass capillary column with Triton X-305. The components were identified by standardless gas chromatographic method with a special computer program. No less than 63 compounds have been found and 54 compounds have been identified, among these primary, secondary and tertiary aliphatic amines as well as heterocyclic bases. The presence of 5 compounds has been confirmed by GC/MS technique. Analysis with the help of a specific flame-photometric detector has shown the presence of 9 bi-functional nitrogen- and sulfur-containing compounds.
