摘要: 采用(乙醇+丙酮)(v/v =1:2)/硫酸铵双水相体系分离螺旋藻β-胡萝卜素,确定其体系组成为15%(乙醇+丙酮)(v/v =1:2)和24%硫酸铵。通过单因素和Box-Behnken实验探讨β-胡萝卜素粗提液、pH、萃取温度对萃取效果的影响。结果表明:β-胡萝卜素粗提液质量分数为6%、体系pH 8.0、萃取温度30 ℃时,萃取率可达94.55%。研究结果为β-胡萝卜素提取分离提供了新途径,双水相萃取技术在天然β-胡萝卜素提取中具有良好应用前景。

Abstract: In this study,an aqueous two-phase system composed of 15% (W/W) ethanol and acetone (v/v=1:2) 24% (W/W) ammonium sulphate was selected to extract β-carotene from Spirulina. The effect of crude extract concentration,pH,extraction temperature on the extraction efficiency of  β-carotene were investigated by single factor and Box-Behnken design methods.The results showed that the optimal conditions for the extraction of β-carotene were:crude extract concentration of 6% (W/W),pH of 8.0 and extraction temperature of 30 ℃.The maximal extraction efficiency (94.55%) was obtained under the optimal conditions.These results suggested that ATPE is efficient in extracting β-carotene and has the potential to be used in natural β-carotene extraction industry.
