摘要:
我国许多中药材中含有有效的抗氧化物质。本文采用水煮法提取甘草、葛根、垂盆草中的抗氧化物质,再利用液-液萃取的方法,分别用石油醚和乙酸乙酯对提取物加以分离提纯。将提取物加入菜籽油中,放入恒温箱中在60℃条件下保存,通过定时测定菜籽油酸价和过氧化值的变化情况,来研究中药材提取物的抗氧化活性,并与茶多酚与VE进行比较。实验结果表明,甘草、葛根、垂盆草提取物均具有良好的抗氧化活性,并可以与茶多酚和VE相媲美。

Abstract: Many Chinese herbal medicines contain effective antioxidant substances. In this article, we extract the antioxidants from the Glycyrrhiza uralensis Fisch, kudzu root and Sedum sarmentosum Bunge by water-cooking method, then the substances were extracted with petroleum ether and ethyl acetate. Put the extractions into the oil, and save the sample in the temperature case of 60℃. Measure the acid value and the peroxide value of the oil, study on the antioxidant activity of extracts of Chinese herbal medicine and compare it with the tea-polyphenols and the VE. The results showed that the extraction from Glycyrrhiza uralensis Fisch, kudzu root and Sedum sarmentosum Bunge exhibited high antioxidative activity comparable to the tea-polyphenols and the VE.
