The study on the antioxidative effect of
yin chen hao tang
Organization: Tainan Municipal Hospital
Author: Ming-feng Chen
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.

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,本研究進一步觀察茵陳蒿湯對急性肝炎患者之全血超氧陰離子(O2()及過氧化氫(H2O2)之清除作用,並進一步探討茵陳蒿湯的組成三種中藥大黃、茵陳蒿及槴子之抗氧化作用。結果發現,茵陳蒿湯水萃取物可以顯著地清除急性肝炎患者全血中的超氧陰離子及過氧化氫,但以清除超氧陰離子的作用較明顯。另一方面,茵陳蒿湯的三種組成生藥大黃、茵陳蒿、槴子之水萃取物都具有清除由黃嘌呤/黃嘌呤氧化脢產生之超氧陰離子的作用,並且能抑制氯化亞鐵誘發大白鼠肝細胞脂質過氧化,三種中藥的抗氧化活性中以大黃最為顯著。由以上結果顯示,茵陳蒿湯能有效地清除急性肝炎患者全血中之氧自由基,而三種組成中藥中又以大黃為最強的抗氧化劑。
