FIELD: medicine, chemistry. SUBSTANCE: method involves extraction of chlorophyll a from spirulina biomass followed by treatment of extract with acid to obtain pheophytin a, its alkaline hydrolysis and isolation of the end product. In preparing pheophytin for hydrolysis its purification is carried out by redissolving pheophytin a in acetone. Chlorine e6. isolated from reaction mixture after termination of hydrolysis is washed out with acidified distilled water. EFFECT: increased yield, enhanced purity of product. 2 cl, 3 ex
