D半乳糖衰老模型小鼠灌胃三才汤水提液、氯仿提取液或乙醇提取液连续30 天,测定肝细胞膜Na +K+ATPase 活力和MDA 含量。结果表明与衰老模型组比较,三才汤氯仿提取液、乙醇提取液和水提液均可显著提高肝细胞膜Na+K+ATPase活力,显著抑制MDA 的生成,提示三才汤抗衰老机制可能与抑制脂质过氧化反应,降低MDA 含量,提高Na +K+ATPase 活力有关 D-galactose aging model mice were given Sancai Decoction, chloroform extract or ethanol extract for 30 consecutive days to determine the Na + -K + ATPase activity and MDA content in hepatic membrane. The results showed that compared with the aging model group, Sancai Decoction extract, ethanol extract and water extract can significantly increase the Na + K + ATPase activity of hepatic cell membrane and significantly inhibit the formation of MDA, suggesting that the anti-aging mechanism of Sancai Decoction may be related to the suppression of lipids. Peroxidation, reduction of MDA content and increase of Na + -K + ATPase activity
