Objective: To study the conditions and parameters of purifying total flavonoids from L. dunnii with AB-8 macroporous resin and to compare with antioxidant ability before and after being purified.
目的：研究AB-8型大孔吸附树脂纯化春花胡枝子总黄酮的条件、参数及纯化前后体外抗氧化能力的变化。
Folin-Ciocalteu method was used to determine the content of total phenols and the DPPH scavenging ability was detected to evaluate its antioxidant properties in this study.
并以Folin - Ciocalteu方法测定总酚含量，检测DPPH清除能力作为抗氧化活性的评估的方法。
The antioxidant test found that the total phenolic, flavonoids and DPPH scavenging ability is higher with in the leaves.
在抗氧化能力方面可发现，总酚类、总类黄酮和DPPH 自由基的清除能力皆以叶 部为最高。
