Evaluation of anti-aging and antioxidant properties of a new rose variety, Ever-rose

Abstract

Abstract Background Rose flowers contain active ingredients such as flavonoids and volatile oils and are acknowledged to be good natural resources owing to their anti-aging and antioxidant properties. In this study, we develop four new rose varieties (named Ever-rose) that are fragrant, pest resistant, and easy to grow. Subsequently, we evaluate the properties of Ever-rose and its potential for use in anti-aging products. Methods The chemical composition of Ever-rose was determined using ultra-high-performance liquid chromatography triple time-of-flight mass spectrometry/mass spectrometry. The antioxidant activity of the Ever-rose extract was evaluated using various assays, including superoxide dismutase activity, 2,2-diphenyl-1-picrylhydrazyl radical-scavenging capacity, and xanthine oxidase activity. The variations in proteolytic matrix metalloproteinase-1 expression, collagen content after ultraviolet (UV) irradiation, and reactive-oxygen-species (ROS) levels after infrared A (IRA) treatment were evaluated. The variations in cell elasticity were assessed via atomic force microscopy. Results The petal extracts of Ever-rose (named ER004(P), ER011(P), ER012(P), and ER015(P)) showed good antioxidant activity. They effectively inhibited UV irradiation-induced MMP-1 expression and IRA irradiation-induced increase in mitochondrial ROS levels. Additionally, they inhibited variations in cell shape and elasticity as aging progressed. In particular, ER011(P) demonstrated the best anti-aging and antioxidant effects. Conclusion The newly developed Ever-rose showed excellent antioxidant and anti-aging effects. In particular, ER011(P) demonstrated the best properties owing to its high antioxidant content. Hence, it exhibits significant potential as a functional cosmetic ingredient. Graphical Abstract
