The carotenoid extract from Dunaliella salina was used to evaluate the suppressive effects on lipopolysaccharide (LPS)-induced pro-inflammatory mediators in RAW264.7 cells. The extract composed all-trans forms of α-carotene (28.8mg/g extract), β-carotene (471.1mg/g extract), lutein (7.1mg/g extract) and zeaxanthin (7.2mg/g extract), 13- or 13′-cis-β-carotene (12.1mg/g extract), 9- or 9′-cis-α-carotene...
A simple HPLC method with good separation efficiency was developed to determine all-trans and cis forms of carotenoids in Dunaliella salina cultivated in Taiwan. The analysis used a C30 column (250×4.6mm, 5μm) and an isocratic solvent system (flow rate=1mL/min) mixing methanol–acetonitrile–water (84/14/2, v/v/v) and methylene chloride, (75/25, v/v). Carotenoids were detected at 450nm. Moreover, the...
