FIELD: medicine.
SUBSTANCE: algae Gracilaria verrucoza are incubated in distilled water in order to transform unsaturated fatty acids under influence of present in alga enzymes into prostaglandins. Prostaglandins are transferred into distilled water. Extraction of prostaglandins from water solution by sorption with further eluting with water-organic solvents is carried out. Freshly collected alga is used, incubation is carried out during 1-3 hours with light illumination with intensity 100-300 mcE/m2s and temperature not higher than 4°C, before extraction of prostaglandins by sorption obtained water solution is acidified to pH 2.5-3.0, as sorbent non-polar modified silicagel with graft hydrocarbons with grain size to 100 mcm.
EFFECT: increase of product yield and process simplification.
