Chemical composition of Spirulina powder

In this study، Spirulina has been cultured in semi mass scale in greenhouse in order to control light and temperature. Since، maximum growth of Spirulina had been observed; they harvested and dried to produce Spirulina powder. Its chemical composition had been analyzed by common methods، then fatty acid and aminoacid profile had been taken by gass chromatography and HPLC device. Also the amount of chlorophil and astaxantine as an important pigments had been measured by spectrophotometry and HPLC. The results showed، protein and fat of Spirulina was 46. 6 and 0. 1 percent، respectively. Chlorophil was 2. 097µg/ml and astaxantin by using astaxantin standard was 0. 21mg/kg.
