Abstract

We analyzed the antioxidant and anti-wrinkle activities of berberine, isolated from dried rhizome of Coptis japonica Makino, to determine its cosmetic potential. We performed the 3-[4,5-dimethylthiazol]-2-yl]-2,5-diphenyl-tetrazoliumbromide (MTT) assay to evaluate the toxicity of the berberine. We also measured the ROS and hyaluronic acid production, and expression of MMP-2, MMP-9, TIMP-1, TIMP-2, and tumor necrosis factor-alpha (TNF-α) to evaluate the antioxidant and anti-wrinkle activities of berberine, respectively. The cytotoxicity of ultraviolet light, in presence of berberine, was measured by the MTT assay using CCD-986sk fibroblasts, and no cytotoxicity was observed at concentrations less than 25 μg/mL. We also found that berberine decreased ROS production in a concentration-dependent manner and promoted the synthesis of hyaluronic acid. Further, berberine reduced the protein levels and mRNA expression of MMP-2 and MMP-9, which are associated with wrinkle formation, and increased the expression of TIMP-1 and TIMP-2. In addition, the inhibitory effect of berberine on TNF-α, known as pro-inflammatory cytokine, was inhibited by TNF-α gene in a concentration-dependent manner. These results suggest that berberine holds cosmetic value owing to its antioxidant activity, by inhibiting ROS production and anti-wrinkle activity by reducing MMP-2 and MMP-9 and increasing TIMP-1 and TIMP-2 expression.
