茵陳蒿湯之抗氧化作用的研究
我們在過去的研究中發現,十二種常用保肝中藥方劑中以茵陳蒿湯的抗氧化活性最為明顯。由於茵陳蒿湯經常被使用於治療急性肝炎,因此,本研究進一步觀察

In our previous study, we found that Inchenhau-Tang(ICHT) is a most strong anti-oxidant among twelve herb drug prescriptions which are popularly used in treatment of liver disease. ICHT is mostly used in treatment of acute hepatitis with jaundice. Therefore, in this study we further investigated the scavenging effect of ICHT on the oxygen radicals including superoxide anion(O2() and hydrogen peroxide(H2O2) in the whole blood of patients with acute hepatitis. On the other hand, we also investigated the anti-oxidative effect of Artemisiae Capillaris Herba (ACH), Gardeniae Fructus (GF), and Rhei Rhizoma (RR) which are composed of ICHT. The results show that, the watery extract of ICHT significantly scavenged both superoxide anion and hydrogen peroxide in the whole blood of patients with acute hepatitis. The scavenging effect of ICHT on superoxide anion was greater than that on hydrogen peroxide. On the other hand, all of watery extracts of three composed herb drugs significantly scavenged superoxide anion produced by xanthine/xanthine oxidase, and markedly inhibited the production of lipid peroxide from rat liver cells induced by FeCl2. Among them, RR had most strong anti-oxidative effect. The above results revealed that watery extract of ICHT can scavenge oxygen radicals in the whole blood of patients with acute hepatitis. Among three composed herb drugs of ICHT, RR is a most important antioxidant.
