Abstract: | Summary The amount and types of prostaglandins present in Antarctic krill (Euphausia superba Dana.) were estimated. Samples of fresh krill were collected during III Antarctic Cruise of RV Polarstern in November 1984. Prostaglandins were extracted, separated by column and thin-layer chromatography and identified as PGA2, PGB2, PGE2, PGF2 . Quantitative measurements were made by a biological method (Vane cascade), concentrations of the most abundant prostaglandins PGE2 and PGF2 being 1.6 and 4 ng/1 g of fresh tissue, respectively. Such low level of prostaglandin would not be harmful when using krill as a food supplement. |
