摘要:

本研究旨在探究高山桑黄(Sanghuangporus alpinus)MS-10、MS-11、MS-12、MS-13菌株菌丝体液体发酵产物的体外抗氧化活性,及其对H2O2诱导的LO2肝细胞氧化损伤的保护作用和对HepG2肝癌细胞增殖的抑制效应。以4株高山桑黄发酵产物为材料,采用DPPH、ABTS及·OH自由基清除实验评价其体外抗氧化能力;通过H2O2诱导建立LO2细胞氧化损伤模型,结合MTT法检测细胞存活率评估其保肝潜力;利用MTT法分析发酵产物对HepG2细胞增殖的抑制作用,评价其抗肝癌活性。结果显示,4种发酵产物均表现出良好的化学抗氧化能力,并呈现浓度依赖性。其中,MS-13菌株对DPPH自由基的清除能力最强,EC50值为0.119 mg/mL;MS-11菌株在清除ABTS自由基和·OH自由基方面效果最佳,EC50值分别为0.040 mg/mL和0.367 mg/mL。在H2O2诱导的LO2细胞损伤模型中,各发酵产物均能呈浓度梯度依赖性地提高细胞存活率,在5 mg/mL浓度下细胞存活率均达到92.88%以上,显著缓解了H2O2引起的氧化损伤。此外,4种发酵产物对HepG2细胞均表现出明显抑制效果,在5 mg/mL处理浓度下,细胞存活率均下降至约65%。研究表明,高山桑黄4个菌株的液体发酵产物均具有显著的抗氧化与保肝作用,并能有效抑制HepG2细胞生长,为高山桑黄这一高海拔特色食药用菌的资源化开发与肝脏疾病防治天然菌物资源的挖掘提供了重要实验依据。

Abstract:

This study aims to investigate the antioxidant activity of mycelium fermentation products from the Sanghuangporus alpinus strains MS-10, MS-11, MS-12, and MS-13, their protective effects against H2O2-induced oxidative damage in LO2 cells, and their inhibitory effects on HepG2 cell proliferation. Using the mycelial fermentation products of these four strains as materials, their in vitro antioxidant activity was evaluated by measuring their scavenging capacity against DPPH, ABTS and ·OH free radicals. An oxidative damage model of LO2 cells was established using H2O2 induction to assess the products' hepatoprotective potential by detecting their effects on cell survival rates. The MTT assay was employed to analyze the impact of fermentation products on HepG2 cell survival rates, evaluating their anti-hepatocellular carcinoma activity. Results demonstrated that all four fermentation products exhibited significant chemical antioxidant capacity with concentration-dependent effects. Specifically, strain MS-13 exhibited the strongest DPPH radical scavenging capacity with an EC50 value of 0.119 mg/mL; strain MS-11 demonstrated optimal efficacy in scavenging ABTS and ·OH radicals, with EC50 values of 0.040 mg/mL and 0.367 mg/mL respectively. In the H2O2-induced LO2 cell damage model, all fermentation products increased cell viability in a concentration-dependent manner. At 5 mg/mL, cell survival exceeded 92.88%, significantly mitigating H2O2-induced oxidative damage. Furthermore, all four fermentation products exhibited marked inhibitory effects on HepG2 cells, reducing survival rates to approximately 65% at a treatment concentration of 5 mg/mL. The study indicates that the liquid fermentation products of the four strains of S. alpinus possess significant antioxidant and hepatoprotective properties, while effectively inhibiting HepG2 cell growth. This provides crucial theoretical support for the further development and utilization of this fungus.
