3D皮肤模型法评价五味子油对H2O2诱导的HaCaT细胞氧化损伤的保护作用

运用3D皮肤模型法评价五味子油对H₂O₂诱导的HaCaT细胞氧化损伤的保护作用。利用水蒸气蒸馏法提取得到五味子油,采用GC-MS分析其化学成分,通过DPPH、ABTS自由基清除实验,以及H₂O₂诱导HaCaT细胞损伤2D、3D皮肤模型评价五味子油的抗氧化作用。结果表明,五味子油中主要化学成分包括依兰烯、β-喜马烯、L-α-蒎烯等37种化合物,五味子油对DPPH、ABTS自由基具有良好的清除效果,其清除率的IC50分别为5.6 mg/m L、9.4 mg/m L;五味子油能提高H₂O₂处理后的HaCaT细胞存活率,增加3D皮肤模型的表皮层厚度,降低白细胞介素-6 (Interleukin-6,IL-6)水平,上调SOD酶和CAT酶活性。研究结果证实,五味子油对H₂O₂诱导的HaCaT细胞氧化应激损伤模型具有保护作用,可为五味子油皮肤抗衰老产品的研发奠定基础。

Protective Effect of Schisandra Chinensis Oil on H2O2-induced Oxidative Stress Injury in HaCaT Cells by 3D Skin Model

The protective effect of Schisandra chinensis oil on H₂O₂-induced oxidative damage of HaCaT cells is evaluated by 3D skin model. Schisandra chinensis oil was extracted by steam distillation, and its chemical constituents analyzed by GC-MS. And the antioxidant activity of schisandra chinensis oil was evaluated by DPPH and ABTS free radical scavenging experiments, combined with 2D and 3D skin models induced by H₂O₂. The results showed that Schisandra chinensis oil mainly contained 37 compounds including ylenene, β-cimarene and L-α-pinene. Schisandra chinensis oil had good scavenging effect on DPPH and ABTS free radicals, with IC₅₀ of 5.6 mg/mL and 9.4 mg/mL, respectively. What’s more, Schisandra chinensis oil can improve the survival rate of HaCaT cells after H₂O₂ treatment, increasing the epidermal thickness of 3D skin model, decreasing the level of Interleukin-6(IL-6), and up-regulating the activities of SOD and CAT enzymes. The results confirmed that Schisandra chinensis oil had protective effect on H₂O₂-induced oxidative stress injury model of HaCaT cells, which could lay a foundation for the development of anti-aging products of schisandra chinensis oil.
