摘要: 为探究蜂胶中4种黄酮成分(高良姜素、短叶松素、松属素、柯因)对胰岛素抵抗的改善作用。通过高浓度胰岛素诱导的方式建立胰岛素抵抗HepG2细胞模型;设立正常组、模型组、高良姜素处理组、短叶松素处理组、松属素处理组、柯因处理组,测定各试验组对HepG2细胞增殖、葡萄糖消耗量、糖原含量、已糖激酶(hexokinase,HK)和丙酮酸激酶(pyruvate kinase,PK)的影响。结果显示:4种黄酮成分在有效浓度范围内对胰岛素抵抗HepG2细胞增殖均无显著影响(P>0.05);柯因、短叶松素作用效果不明显(P>0.05);高良姜素和松属素均能不同程度地提高IR-HepG2细胞葡萄糖消耗量(glucose consumption,GC)、肝糖原含量、HK和PK活力(P<0.05)。上述结果表明蜂胶中高良姜素和松属素能较好地调节IR-HepG2糖代谢,改善胰岛素抵抗,为蜂胶产品的深度开发提供参考。

Abstract: To determine the effect of 4 flavonoids (pinobanksin, galangin, chrysin, pinocembrin) from propolis on improvement of insulin resistance in vitro, this paper induced insulin resistance cell model by high concentration of insulin. Effects of every treatment group on cell proliferation of HepG2, glucose consumption, intracellular glycogen content, hexokinase activity and pyruvate kinase activity were determined. The results showed that different concentrations of flavonoids had no significant effect on proliferation of HepG2 cells under effective concentration(P>005). Chrysin and pinobanksin had little impact on HepG2 cell(P>0.05). Galangin and pinocembrin could increase glucose consumption, hepatic glycogen content, HK and PK activities of IR-HepG2 cells by different degree(P<005). These results indicated that galangin and pinocembrin could regulate glucose metabolism of HepG2 cells, and improve hepatic insulin resistance. Thus, this study provided reference for in-depth development of propolis products.
