| 摘 要： | 目的研究连翘不同部位及其中连翘酯苷和连翘苷2种化学成分的抗氧化作用。方法用清除有机自由基DPPH法评价抗氧化作用,并通过HPLC-PDA法测定了连翘酯苷和连翘苷在不同部位的含量。结果连翘不同部位及其中2种化学成分对DPPH自由基均有一定的清除作用,具有抗氧化能力。结论连翘酯苷的抗氧化能力大大优于连翘苷,是一种优秀的天然抗氧化剂。

| Abstract: | Objective To study the antioxidant activities of different parts of Forsythia suspensa and two components isolated from it. Methods The antioxidant activities were assayed through scavenging effects to DPPH radical. The content of forsythiaside and forsythin of Forsythia suspensa was determined by HPLC- PDA. Results Both different parts of Forsythia suspensa and two components isolated from it had antioxidant activity. Conclution Forsythiaside showed much higher antioxidant activity than forsythin. It is an... |
