摘要:: 以银叶树果壳为试材，采用碱水浸提法，研究了不同提取因素对银叶树果壳棕色素提取率的影响，并对棕色素的稳定性和抗氧化性进行研究，以期为开发和利用银叶树资源提供相应的技术支持。结果表明：最佳的提取条件为提取时间2.0 h，pH 11，提取温度70 ℃，料液比1∶40 g?mL-1。棕色素的稳定性研究表明，棕色素的耐光性较差，H2O2、Mg2+、Na+对棕色素稳定影响不大，Na2SO3、Pb2+、Fe3+和Al3+对棕色素稳定性的作用明显。抗氧化性研究表明，银叶树果壳棕色素具有较强的清除羟自由基、超氧阴离子自由基和DPPH自由基的能力。

Abstract:: With silver leaf tree husk were used as materials,alkaline water extraction method was used,the effect of different extraction factors on the extraction rate of brown pigment were studied from the husk of silver leaf tree,and the stability and antioxidant properties of the pigment were studied,in order to provide corresponding technical support for the development and utilization of silver leaf tree resources.The results showed that the optimal extraction conditions were as follows extraction time 2.0 hours,pH 11,extraction temperature 70 ℃,solid-liquid ratio 1∶40 g?mL-1.Research on the pigment stability showed that brown pigment exhibited poor lightfastness,H2O2,Mg2+,Na+ had a litter effect on brown pigment,while Na2SO3,Pb2+,Fe3+ and Al3+ had obvious effect on the stability of brown pigment.Research on antioxidant activity showed that brown pigment of silver leaf tree husk had strong scavenging effect on hydroxyl radical,superoxide anion free radical and DPPH radical.
