, renowned for its antibacterial and antioxidant properties, remains relatively unexplored in its impact on melanogenesis. This study delves into the antimelanogenic potential of the ethanol extract derived from (BPE). Our investigations reveal the robust antioxidant capabilities of the BPE, along with its effective inhibition of mushroom tyrosinase activity. Remarkably, these effects were significantly stronger than those observed with arbutin, the positive control. In vitro assays demonstrate the BPE's efficacy in reducing the melanin content and tyrosinase activity in α-MSH-stimulated B16F10 cells. Immunofluorescence and qPCR analyses further reveal the BPE's ability to inhibit MITF-mediated gene expression levels associated with melanogenesis, including , , and tyrosinase. These findings suggest that the extract operates through dual mechanisms, suppressing both tyrosinase activity and key transcription factor-mediated downstream signaling. Utilizing UPLC-MS/MS analysis, we identified six key compounds implicated in tyrosinase activity inhibition and melanogenesis suppression. Docking simulations confirm moderate binding affinities between these compounds and tyrosinase. This study highlights the potential of as a novel natural agent for depigmentation in medicinal and cosmetic applications, elucidating its dual mechanism of action in melanogenesis inhibition.
, 以其抗菌和抗氧化特性而闻名,但在其对黑色素生成的影响方面仍相对未被探索。本研究深入探讨了 (BPE)乙醇提取物的抗黑色素生成潜力。我们的研究揭示了 BPE 强大的抗氧化能力,以及其对蘑菇酪氨酸酶活性的有效抑制作用。值得注意的是,这些效果明显强于阳性对照熊果苷。体外实验表明,BPE 能有效降低 α-MSH 刺激的 B16F10 细胞中的黑色素含量和酪氨酸酶活性。免疫荧光和 qPCR 分析进一步表明,BPE 能够抑制 MITF 介导的与黑色素生成相关的基因表达水平,包括 、 、 和酪氨酸酶。这些发现表明,该提取物通过双重机制发挥作用,抑制酪氨酸酶活性和关键转录因子介导的下游信号转导。利用 UPLC-MS/MS 分析,我们鉴定出了 6 种与抑制酪氨酸酶活性和黑色素生成相关的关键化合物。对接模拟证实了这些化合物与酪氨酸酶之间具有中等的结合亲和力。本研究强调了 作为一种新型天然美白剂在医药和化妆品应用中的潜力,阐明了其在黑色素生成抑制中的双重作用机制。
