The genus spp. has long been recognized as a healing herb for its use in treating fever, inflammation, and pain relief, as well as a food source for its nutritional value. In this study, we aimed to explore the potential bioactive natural products in the leaves of , commonly known as Korean pussy willow, for their protective effects against skin damage, including aging. Utilizing LC/MS-guided chemical analysis of the ethanol extract of leaves, with a focus on major compounds, we successfully isolated two main phenolic compounds, tremulacin () and tremuloidin (). Subsequently, we investigated the protective effects of tremulacin () and tremuloidin () in TNF-α-stimulated human dermal fibroblasts (HDFs). The results revealed that both tremulacin () and tremuloidin () inhibited TNF-α-stimulation-induced ROS, suppressed matrix metalloproteinase-1 (MMP-1) expression, and enhanced collagen secretion. This implies that both tremulacin () and tremuloidin () hold promise as preventive agents against photoaging-induced skin aging. Furthermore, we assessed the activity of mitogen-activated protein kinases (MAPKs), cyclooxygenase-2 (COX-2), and heme oxygenase 1 (HO-1) to elucidate the mechanism of photoaging inhibition by tremuloidin (), which exhibited superior efficacy. We found that tremuloidin () inhibited ERK and p38 phosphorylation and notably suppressed COX-2 expression while significantly upregulating HO-1 expression. These findings suggest potent anti-inflammatory and antioxidant properties of tremuloidin (), positioning it as a potential candidate for combating photoaging-induced skin aging.

柳树叶中主要酚类化合物、tremulacin 和 tremuloidin 对 TNF α刺激的人真皮成纤维细胞的潜在皮肤抗衰老作用
长期以来,该属 spp. 一直被认为是一种用于治疗发烧、炎症和缓解疼痛的治疗草药,以及由于其营养价值而成为食物来源。在这项研究中,我们旨在探索通常被称为韩国猫柳叶子中潜在的生物活性天然产物,因为它们对皮肤损伤(包括衰老)具有保护作用。利用 LC/MS 引导下对叶片乙醇提取物进行化学分析,重点关注主要化合物,我们成功分离了两种主要酚类化合物,tremulacin () 和 tremuloidin ()。随后,我们研究了 tremulacin () 和 tremuloidin () 在 TNF α刺激的人真皮成纤维细胞 (HDF) 中的保护作用。结果显示,tremulacin () 和 tremuloidin () 均抑制 TNF α刺激诱导的 ROS,抑制基质金属蛋白酶-1 (MMP-1) 表达,并增强胶原蛋白分泌。这意味着 tremulacin () 和 tremuloidin () 都有希望成为预防光老化引起的皮肤老化的药物。此外,我们评估了丝裂原活化蛋白激酶 (MAPK) 、环氧合酶-2 (COX-2) 和血红素加氧酶 1 (HO-1) 的活性,以阐明 tremuloidin () 抑制光老化的机制,表现出卓越的疗效。我们发现 tremuloidin () 抑制 ERK 和 p38 磷酸化,显著抑制 COX-2 表达,同时显著上调 HO-1 表达。这些发现表明 tremuloidin () 具有强大的抗炎和抗氧化特性,使其成为对抗光老化引起的皮肤老化的潜在候选者。
