Photosensitiser and method for production thereof

摘要

The invention relates to medicine and concerns a photosensitiser for detecting and curing tumors. The inventive photosensitiser is embodied in the form of a composition containing chlorine in the form of salt and alkali metals. 80-90% of chlorine e6, 5-20% of purpurin 5 and the rest being purpurin 18 are used as chlorine. Said photosensitiser is produced by extracting Spirulina biomass with the aid of aceton. Afterwards said biomass is exposed to acid treatment, neutralisation, hydrolysis, extraction of feoforbide alpha , dissolution in aceton, addition of a strong base, neutralisation and reprecipitation of chlorine 6.
