过路黄在食用油脂中抗氧化作用的研究

THE ANTIOXIDATIVE ACTIVITY OF LYSIMACHIA CHRISTINAE HANCE FOR EDIBLE OILS AND FATS

经过实验,首次筛选出中草药——过路黄(Lysimachia christinae Hance)在油脂中具有较强的抗氧化作用。过路黄在我国分布很广,并且价廉、无毒,作为油脂抗氧化剂具有一定的社会和经济效益.过路黄的乙醚提取物在菜籽高级烹调油中的抗氧化作用显著高于α-VE 及人工合成抗氧化剂 BHT 的作用,在猪油中也有较强的抗氧化作用;研究了增效剂柠檬酸对提取物的增效作用;采用化学显色法初步推断其有效的抗氧成分为酚类、黄酮类及甾醇类化合物.

This paper deals with the screening results of antioxidative activityof some traditional Chinese medicines by AOM method Lysimachia christinaeHauce,has been used as a traditional Chinese medicines in China for a longtime,but its antioxidative effective bas been first reported in this paper.Its ether extract showed stronger activity than that of α-tocopherol andBHT in rapeseed Cooking oil,It also exhibited strong activity in lard.The action of citric acid as synergist with ether extract had researched.The color-test resutts showed that the antioxidative substances in Lysima-chia christinae Hance be phenols,flavonoids and sterols
