Current aspects of standardization of Spirulina platensis biomass

The food spirulina [Spirulina platensis (Nordst.) Geitl.] is a blue-green multicellular filamentous microscopic alga widely cultivated in many countries of the world, including the Russian Federation. The aim of this study is to develop approaches to the standardization of biomass of Spirulina platensis. As a result of the conducted research, approaches to the standardization of biomass of Spirulina platensis have been developed. It is aimed to determine the content of β-carotene, phycocyanin and proteins by using TLC and spectrophotometry. It was determined that the content of β-carotene in the samples of biomass of Spirulina platensis calculated on absolutely dry raw material varies from 63.0 mg% to 94.0 mg%, phycocyanin from 3.50% to 4.30% and protein from 53.50% to 61.09%. It was established that β-carotene, C-phycocyanin and protein were the most important diagnostically significant biologically active compounds of the biomass of Spirulina platensis. The analytical aspects of the study of Spirulina platensis biomass considered in this paper are the scientific basis for the substantiation of the creation of pharmaceuticals based on it.
