(), widely used in tropical and subtropical regions, has been reported to possess good anti-aging benefits on skincare. However, the potential bioactive components responsible for its anti-aging effects, including anti-collagenase, anti-elastase, and anti-hyaluronidase activities, have not been clarified so far. In this study, leaf extracts were first conducted for anti-elastase and anti-collagenase activities by spectrophotometric and fluorometric assays, and the results revealed that they possessed good activities against skin aging-related enzymes. Then, multi-target bio-affinity ultrafiltration coupled to high-performance liquid chromatography-mass spectrometry (AUF-HPLC-MS) was applied to quickly screen anti-elastase, anti-collagenase, and anti-hyaluronidase ligands in leaf extracts. Meanwhile, 10, 8, and 14 phytochemicals were screened out as the potential anti-elastase, anti-collagenase, and anti-hyaluronidase ligands, respectively. Further confirmation of these potential bioactive components with anti-aging target enzymes was also implemented by molecule docking analysis. In conclusion, these results suggest that the leaves might be a very promising natural source of anti-aging agent for skincare, which can be further explored in the cosmetics and cosmeceutical industries combating aging and skin wrinkling.
()广泛应用于热带和亚热带地区,据报道在护肤品方面具有良好的抗老化功效。然而,其抗老化作用所涉及的潜在生物活性成分,包括抗胶原酶、抗弹性蛋白酶和抗透明质酸酶活性,迄今为止尚未明确。在本研究中,首先通过分光光度法和荧光分析法对叶提取物进行抗弹性蛋白酶和抗胶原酶活性检测,结果表明它们对与皮肤老化相关的酶具有良好的活性。然后,采用多靶点生物亲和超滤结合高效液相色谱 - 质谱联用技术(AUF - HPLC - MS)快速筛选叶提取物中的抗弹性蛋白酶、抗胶原酶和抗透明质酸酶配体。同时,分别筛选出10种、8种和14种植物化学物质作为潜在的抗弹性蛋白酶、抗胶原酶和抗透明质酸酶配体。还通过分子对接分析对这些具有抗老化靶标酶的潜在生物活性成分进行了进一步确认。总之,这些结果表明叶可能是一种非常有前景的用于护肤品的抗老化剂天然来源,可在化妆品和药妆行业中进一步探索以对抗衰老和皮肤皱纹。
