摘要

The antioxidant capacity of the human body is closely related to its ability of disease resistance and anti-aging. It is a current research focus to find effective anti-oxidants used in medicine, food, health care, beauty make-up from natural plants. In this paper, we studied the content of selenium in selenium polysaccharide and its antioxidant activity in vitro of Thlaspi caerulescens L. produced from Yutangba of Enshi selenium mining area. The double tracts atomic fluorescence spectrometry is used to detect the total selenium content in the sample and that of selenium polysaccharide in the active ingredient of the sample. The salicylic acid method and pyrogallol autoxidation method are used to detect the scavenging activity of selenium polysaccharide on hydroxyl radicals and superoxide anion. Experiments show that the total amount of selenium in Thlaspi caerulescens L. is 708ug.g~(-1), while the amount of selenium in selenium polysaccharide is 98.lug.g~(-1), accounting 13.86% of the total selenium content. Meanwhile, selenium polysaccharide in samples is with significant antioxidant capacity, and it shows a certain dose-effect relationship. Selenium polysaccharide has stronger anti-oxidation ability than pure polysaccharide compared with non-selenium polysaccharide. Therefore, plants rich in selenium are better natural antioxidants. This study will provide the necessary experimental basis for the effective and rational development and utilization of Thlaspi caerulescens L. rich in seleniumModern medicine proves that excessive free radicals in the body can cause inflammation, cancer, and ischemic disease and accelerate aging, etc.. As a result, it has become a hot spot to study the anti-oxidants to remove excessive free radicals. For current synthetic antioxidants, there are problems of high toxic side effects, poor thermal stability and many other shortcomings. Therefore, looking for antioxidants of efficiency and low toxicity such as natrual green plants has been a necessary step.
