植物和人类一样,需要光保护,以防止过度暴露在紫外线辐射下的潜在破坏性影响。在此之前,苹果酸sinapoyl (SM)被认为是海藻中的光保护剂。在这里,我们试图在一种类似的植物,花园菜中识别光保护剂,它目前被用于护肤产品解毒芬nc。为了实现这一目标,我们利用飞秒瞬态电子吸收光谱研究了甘蓝芽提取物和解毒素nc的光动力学。通过液相色谱-质谱联用分析,确定了甘蓝提取物中主要吸收紫外的化合物为SM。重要的是,我们的研究表明,在解毒素c中存在的花园菜芽提取物中的SM的光保护特性不受配方环境的影响。结果表明,含有花园菜芽提取物的解毒素nc可能以紫外线过滤增强剂的形式为最终用户提供额外的光保护。
Plants, as with humans, require photoprotection against the potentially damaging effects of overexposure to ultraviolet (UV) radiation. Previously, sinapoyl malate (SM) was identified as the photoprotective agent in thale cress. Here, we seek to identify the photoprotective agent in a similar plant, garden cress, which is currently used in the skincare product Detoxophane nc. To achieve this, we explore the photodynamics of both the garden cress sprout extract and Detoxophane nc with femtosecond transient electronic absorption spectroscopy. With the assistance of liquid chromatography-mass spectrometry, we determine that the main UV-absorbing compound in garden cress sprout extract is SM. Importantly, our studies reveal that the photoprotection properties of the SM in the garden cress sprout extract present in Detoxophane nc are not compromised by the formulation environment. The result suggests that Detoxophane nc containing the garden cress sprout extract may offer additional photoprotection to the end user in the form of a UV filter booster.
