摘　　要：以我国特有的天然资源五倍子为原料,研制了几种没食子酸衍生物作为油脂抗氧化剂。评价了没食子酸丙酯、没食子酸月桂酯、鞣花酸、单宁酸、以及协合剂抗坏血酸棕榈酯对豆油和莱子油的抗氧化效果。对常见的没食子酸丙酯提出一种尚未见报道的制备方法,可以大幅度地降低生产成本。使用极谱仪和以血红素为催化剂,制定了评价抗氧化剂活性的快速测试方法,具有省料、省时、易于操作、重现性较好等特点。From Chinese gall nut as raw material some derivates of gallic acid were prepared as antioxidant for edible oil. The antioxidant activities of propyl gallate,lawyl gallate ,tannic acid,ellagic acid and 1-ascorbyl palmitate were evaluated in soybean oil and rapeseed oil. A new processing method of propyl gallate was advanced in order to decrease the cost of production. A polarographic test which has many advantages ,such as time-saving and good repeatability was developed for evaluating antioxidant activity.
