| 摘 要： | 板栗壳色素兼具着色剂和抗氧化剂的双重作用,分别以70%乙醇和氨水(pH11)为溶剂提取板栗壳色素,对2种提取方法在色素的得率、紫外-可见光光谱以及抗氧化活性方面作了比较研究,以期为板栗壳色素的开发利用提供理论依据。醇提法所得色素色价较高,但在抗脂质过氧化、清除羟自由基和1,1-二苯基-2-苦基肼自由基活性以及还原力方面都不及碱提法所得色素,两种方法所得色素对超氧阴离子自由基的清除能力都很弱。 |

| Abstract: | Chestnut shell pigments can play a dual role as a colorant and antioxidant.To provide the theoretical information for the utilization of the pigments,70% ethanol and aqueous solution of ammonia(pH11)were used as solvents,and pigment yields,ultraviolet-visible light spectra and antioxidant activities of the pigments obtained were compared.The pigment extracted by the ethanol had a higher color value than that by the alkali.However,the anti-lipid peroxidation,removal efficiency to hydroxyl and 1,1-diphenyl-2-picryl-hydrazyl radicals,and reducing power for the pigment extracted by the ethanol were lower than that by the alkali.In addition,the superoxide anion radical scavenging activity of both methods was very weak. |
