摘　　要：To search for the protective actions of blumea flavanones (BFs) on hepatocytes and hepatic subcellular organelle against lipid peroxidation, monkey′s hepatocytes were isolated and cultured with or without blumea flavanones, then damaged by FeSO 4 cysteine or CCl 4. The lipid peroxidation (malondialdehyde production) and alteration in hepatocyte membrane (leakage of GPT) were estimated. Hepatic subcellular organelles were also isolated and incubated with or without blumea flavanones, then injured by FeSO 4 ascorbate. The generation of malondialdehyde(MDA) was measured. It was found that BFs 10 and 100 μmol·L 1 inhibited the MDA generation and GPT (glutamic pyruvic transaminase) leakage out of hepatocytes that were induced by CCl 4 or FeSO 4 cysteine. BFs could prevent lipid peroxidation initiated by FeSO 4 ascorbate in subcellular organelle suspension. Among BFs, BF 2 possessed the strongest activity. Conclusion: Blumea flavanones possess antioxidation activities that protect monkey′s hepatocytes and hepatic subcellular organelle against injuries induced by FeSO4 or CCl 4.目的：研究艾纳香二氢黄酮对脂质过氧化致损伤的恒河猴原代培养肝细胞及肝亚细胞的保护作用。方法：艾纳香二氢黄酮与原代培养肝细胞共育后，以ＣＣｌ４或ＦｅＳＯ４半胱氨酸致细胞损伤，以脂质过氧化产物丙二醛产生量及转氨酶的漏出量作为损伤程度指标。亚细胞结构与艾纳香二氢黄酮共育后，以ＦｅＳＯ４半胱氨酸致脂质过氧化，以丙二醛产生量衡量过氧化损伤程度。结果：１０及１００μｍｏｌ·Ｌ１的艾纳香二氢黄酮可降低被损伤的肝细胞中的丙二醛产生，降低转氨酶漏出，抑制肝亚细胞结构中丙二醛生成。结论：艾纳香二氢黄酮具有抑制脂质过氧化作用及肝细胞。
