Изобретение относится к улучшенному способу получения хлорина е6. Получение хлорина е6 осуществляют при использовании в качестве источника сырья биомассы цианобактерий, например рода Spirulina, полученной путем выращивания цианобактерий в условиях искусственного или солнечного освещения на искусственных питательных средах, имеющих рН 8,0 - 12,0, с предварительной обработкой биомассы спиртовым раствором щелочи. Из подготовленного таким образом сырья получают спиртовой экстракт хлорофилла "а", который обрабатывают кислотой с получением феофитина "а". Феофитин промывают неполярным растворителем, например гексаном, и подвергают омылению до образования целевого продукта, который осаждают при обработке соляной кислотой.The invention relates to an improved method for producing chlorin e 6 . Chlorin e 6 is produced when cyanobacteria are used as a biomass source, for example the genus Spirulina, obtained by growing cyanobacteria under conditions of artificial or solar illumination on artificial nutrient media having a pH of 8.0 - 12.0 with pretreatment of the biomass with an alcohol solution . From the raw material prepared in this way, an alcoholic extract of chlorophyll "a" is obtained, which is treated with an acid to produce pheophytin "a". Pheophytin is washed with a non-polar solvent, such as hexane, and subjected to saponification until the formation of the target product, which is precipitated by treatment with hydrochloric acid.
