This study investigated biological activities including antioxidative stress, anti-inflammation, and anti-insulin resistance of aqueous extract (ABE). The results showed abilities of ABE to scavenging DPPH and ABTS free radicals in a dose-dependent manner. Besides, ABE significantly reduced nitric oxide (NO) production in the lipopolysaccharide (LPS)-treated RAW 264.7 via inhibition of mRNA and protein expressions of nitric oxide synthase (iNOS). The LPS-induced mRNA expressions of cyclooxygenase-2 (COX-2) and interleukin 1β (IL-1β) were suppressed by ABE. Moreover, ABE exerted anti-insulin resistance activity as it significantly improved the glucose uptake in tumor necrosis factor (TNF)-α treated 3T3-L1 adipocytes. In addition, ABE at the concentration of up to 200 μg/mL was not toxic to human peripheral blood mononuclear cells (PBMCs) and did not induce mutations. Finally, the results of our study suggest the potential use of as anti-inflammatory, anti-insulin resistance agents, or food supplement for prevention of chronic diseases.
本研究调查了水提取物(ABE)的生物活性,包括抗氧化应激、抗炎和抗胰岛素抵抗。结果表明,ABE具有以剂量依赖性方式清除DPPH和ABTS自由基的能力。此外,ABE通过抑制一氧化氮合酶(iNOS)的mRNA和蛋白质表达,显著降低了脂多糖(LPS)处理的RAW 264.7细胞中一氧化氮(NO)的产生。LPS诱导的环氧化酶-2(COX-2)和白细胞介素1β(IL-1β)的mRNA表达受到ABE的抑制。此外,ABE具有抗胰岛素抵抗活性,因为它显著改善了肿瘤坏死因子(TNF)-α处理的3T3-L1脂肪细胞中的葡萄糖摄取。此外,浓度高达200μg/mL的ABE对人外周血单个核细胞(PBMCs)无毒,也不诱导突变。最后,我们的研究结果表明,ABE有潜力用作抗炎、抗胰岛素抵抗药物或预防慢性病的食品补充剂。
