摘要: Haloterrigena turkmenica was able to synthesize carotenoids when grown in halobacteria medium. These molecules have antioxidant properties and find application food, cosmetic, pharmaceutical fields. The were extracted with methanol, separated by RP-HPLC, identified mass spectrometry UV/Vis spectra analyses. C50 the main pigments, C30, C40, C51 also detected. Seven geometric isomers distinguished for bacterioruberin, monoanhydrobacterioruberin, bisanhydrobacterioruberin. assignment a specific isomer tentatively attempted through analysis of corresponding spectrum, intensity cis peak, its spectral fine structure. Lycopene, phytoene, lycopersene among minor further identified. extract displayed power higher than alpha-tocopherol, butylhydroxytoluene, ascorbic acid used as reference compounds. Our studies first time seven bacterioruberin derivatives 30 haloarchaeon.
