3种中草药提取物的多酚含量及抗氧化性
Comparative study on anti-oxidative capacity and polyphenol content of 3 kinds of the extract of Chinese herbal medicine plants
摘要
Abstract
Folin-Ciocalteu and spectrophotometer were adopted to analyse the polyphenol content and DPPH scavenging activityof 3 kinds of extracts from Chinese herbal medicine plants. The results showed that the extract of Citrus aurantum had highest polyphenol contents, which contained (462.5 ± 19.28) mg/g; the second was the extract of lotus leaf and the third was the extract of Cassia normame, containing(293.8±78.57) mg/g and (270.3±28.53) mg/g. The extract of Cassia normame had highest DPPH scavenging activity. The second and the third were the extract of Lotus leaf and Citrus aurantum. The data of IC50 were in the order of (0.021 ±0.003), (0.037±0.007) and (0.061 ±0.010) mg/mL. After comparing the ability of anti-oxidation of 3 herbal medicine plants, it was found that there was no positive relationship between polyphenol contents and anti-oxidative capacity.关键词
