通过在紫外285nm处测定抗氧化活性物质(蛋白质、芳族胺、酚类等化合物)的含量,在450nm处测定类胡萝卜素的含量,采用DPPH法测定不同溶剂橡子提取物的自由基消除能力,测定羟自由基消除活性及橡子提取物对α-葡萄糖苷酶的抑制作用,研究麻... 通过在紫外285nm处测定抗氧化活性物质(蛋白质、芳族胺、酚类等化合物)的含量,在450nm处测定类胡萝卜素的含量,采用DPPH法测定不同溶剂橡子提取物的自由基消除能力,测定羟自由基消除活性及橡子提取物对α-葡萄糖苷酶的抑制作用,研究麻栎橡子抗氧化活性及抗糖尿病活性。结果表明:70%甲醇提取物中的抗氧化活性物质含量最高,而水提取物中最少;70%甲醇提取物和70%乙醇提取物的类胡萝卜素含量较高;70%甲醇提取物的DPPH自由基的消除能力最强;橡子的水提取物对羟自由基的清除作用最强;甲醇提取物的α-葡萄糖苷酶抑制率较高。说明麻栎橡子具有抗氧化活性和抗糖尿病作用。 展开更多

The aftermath of the war had devastating consequences on people’s lives and society as a whole.In addition to the significant impact of the Great Depression on social production and living standards,it resulted in psychological trauma,unemployment,poverty,and social conflicts.As a prominent English poet that emerged after World War II,Geoffrey Hill depicted the gruesome realities of war through his early works.This article applies Cathy Caruth’s trauma theory to analyze Hill’s poem“Funeral Music.”The fragmented images and repetitive traumatic scenes restore the harsh realities of war.Furthermore,this article explores Joshua Pederson’s critical development of Caruth’s theoretical framework,providing an alternate perspective for textual analysis. 展开更多
