野坝子总黄酮提取工艺及抗氧化活性研究
Study on the extraction technology and antioxidant activity of total flavonoids from the foliage of Elsholtzia rugulosa Hemsl.
摘要
Abstract
This study aims to investigate the extraction methods and antioxidant activity of total flavonoids from Elsholtzia rugulosa Hemsl.foliage.The extraction process for total flavonoids from Elsholtzia rugulosa Hemsl.foliage was optimized using an ultrasound-assisted method based on single-factor experiments combined with response surface methodology,and their antioxidant activity was systematically evaluated.The results indicate that the optimal extraction conditions for total flavonoids are extraction time 25 min,liquid-to-solid ratio 15 mL/g,and ethanol volume fraction 80%.Under these conditions,the extraction yield of total flavonoids reached 5.71%.The extract exhibited excellent antioxidant activity,with IC50 values of 43.707 μg/mL for DPPH radical scavenging capacity and 54.012 μg/mL for ABTS radical scavenging capacity.These findings provide essential process parameters and a theoretical foundation for the development of E.rugulosa Hemsl.in functional foods and natural antioxidant applications.关键词
