中文摘要: 对铜藻多酚提取工艺、稳定性及其对酪氨酸酶活性的抑制作用进行研究。以新鲜铜藻为原料提取铜藻多酚,以铜藻多酚提取率为指标,考察乙醇体积分数、提取时间、液料比对铜藻多酚提取率的影响,并根据Box-Behnken试验设计对铜藻多酚的提取条件进行优化,得到铜藻多酚的最佳提取条件:乙醇体积分数40%、超声时间53 min、液料比为60∶1(mL/g),在该条件下所制备的铜藻多酚具有较高的热和光照稳定性。以左旋酪氨酸和左旋多巴为底物,铜藻多酚浓度为700 μg/mL 时,对酪氨酸酶活性的抑制率分别为92.68%和39.18%。
Abstract:The extraction process,stability,and inhibitory effect on tyrosinase activity of polyphenols from Sargassum horneri were studied. Polyphenols were extracted from fresh S. horneri. The effects of ethanol volume fraction,extraction time and liquid-to-solid ratio on the yield of polyphenols from S. horneri were investigated. Box-Behnken design was then employed to optimize the extraction conditions. The optimum extraction conditions of S.horneri polyphenols were as follows:ethanol volume fraction of 40%,ultrasonic time of 53 min,and liquid-to-solid ratio of 60∶1(mL/g). The S. horneri polyphenols prepared under the optimum conditions had high thermal and light stability.With L-tyrosine and L-dopa as substrates,the inhibition rates of 700 μg/mL S.horneri polyphenols on tyrosinase activity were 92.68% and 39.18%,respectively.
