为探讨茵陈蒿汤醇提物的保肝作用与机体抗氧化能力的关系，实验观察茵陈蒿汤醇提物在Ｄ─氨基半乳糖＋脂多糖（Ｄ—ＧａｌＮ＋ＬＰＳ）和卡介苗＋脂多糖（ＢＣＧ＋ＬＰＳ）模型中对ＡＬＴ、ＧＳＴ、ＬＰＯ、ＳＯＤ及ＧＳＨ的影响。结果：茵陈蒿汤醇提物ｉｇ．６ｇ／ｋｇ和９ｇ／ｋｇ明显降低Ｄ—ＣａｌＮ＋ＬＰＳ肝损伤小鼠血清谷丙转氨酶（ＡＬＴ）活性，降低谷胱甘肽─Ｓ─转移酶（ＧＳＴ）水平，减少肝匀浆中脂质过氧化物（ＬＰＯ）含量，对超氧化物歧化酶（ＳＯＤ）活性无明显影响；４ｇ／ｋｇ，６ｇ／ｋｓ和９ｇ／ｋｓ显著降低ＢＣＧ＋ＬＰＳ免疫性肝损伤小鼠血清ＡＬＴ水平，６ｇ／ｋｇ和９ｇ／ｋｇ增加肝匀浆还原型谷胱甘肽（ＧＳＨ）含量。表明茵陈蒿汤醇提物经口给药能明显提高小鼠抗自由基损伤的能力，为其保肝作用的机理之一。
In order to investigate the relationship between the hepatoprotective effect of the alcohol extract of Yinchenhao Tang and the antioxidant capacity of the body, the alcohol extract of Yinchenhao decoction was observed to be D-galactose+lipopolysaccharide (D-GalN+LPS) and BCG+lipopolysaccharide ( The effects of ALT, GST, LPO, SOD and GSH in the BCG+LPS) model. Results: Yinchenhao soup alcohol extract ig. 6g/kg and 9g/kg significantly reduced serum alanine aminotransferase (ALT) activity, reduced glutathione-S-transferase (GST) levels in D-CalN+LPS liver injury mice, and reduced lipid peroxides in liver homogenates. (LPO) content had no significant effect on superoxide dismutase (SOD) activity; 4g/kg, 6 g/ks and 9 g/ks significantly reduced serum ALT levels in mice with BCG+LPS immunological liver injury, 6 g/kg and 9 g/kg Increase the liver homogenate reduced glutathione (GSH) content. It was shown that oral administration of alcohol extract of Yinchenhao Decoction can significantly improve the ability of mice to resist free radical damage, which is one of the mechanisms of liver protection.
