内蒙古草原16种植物提取物抗氧化活性研究
Study on Antioxidant Activity of Extracts from 16 Plants in Inner Mongolia Grassland
摘要
Abstract
To investigate the antioxidant activity of plant extracts from Inner Mongolia grassland,16 grassland plant species collected from Dalate Banner and Ulgai grassland were used as experimental materials.The contents of total phenolic,total flavonoid,total polysaccharide,and total saponin in the extracts were determined using the Folin-Ciocalteu method,aluminum chloride colorimetric method,concentrated sulfuric acid-phenol colorimetric method,and vanillin-perchloric acid colorimetric method,respectively.Antioxidant activity was evaluated using DPPH and ABTS free radical scavenging rates along with the total antioxidant capacity as indicators.The results showed that significant differences were in the content of these component and antioxidant activity among the 16 plant extracts.Sanguisorba officinalis and Koenigia divaricata exhibited the highest total phenolic content,reaching 33.22%and 29.34%,respectively.Koenigia divaricata also had the highest total flavonoid content,at 17.72%.Moreover,the extracts of Sanguisorba officinalis and Koenigia divaricata exhibited the strongest DPPH and ABTS radical scavenging abilities and the highest total antioxidant capacity.This study clarifies the high antioxidant activity plant resources in Inner Mongolia grassland,and provides scientific theoretical support for the antioxidant functions,pharmaceutical and functional product development of grassland plants,and the sustainable utilization of grassland plant resources.关键词
