Antioxidant and antiaging activities of Jasminum Sambac extract, and its compounds

Aging is a complex process characterized by a progressive decline in physiological function, followed by dysfunction, and ultimately, death. Increase activity of hyaluronidase, elastase and collagenase, are documented in skin aging. Free radicals can stimulate skin aging through antioxidant system destruction, wrinkle formation, and melanogenesis. Antioxidant and anti-aging agents have been recently developed from herbal plants. In this study, we investigated the antioxidant and anti-aging activities of Jasminum sambac extract (JSE). The phytochemical assay was performed with modified Farnsworth method. Antioxidant assays were measured by 2,2-diphenyl-1- picrylhydrazyl (DPPH) scavenger, Ferric Reducing Antioxidant Power (FRAP) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS)-reducing activities. Anti-aging properties were measured through inhibitory activities of collagenase, elastase, and hyaluronidase. Phytochemical analysis showed presence of phenols, triterpenoids, and flavonoids in low level, and terpenoids in high level. JSE showed higher DPPH-scavenging activity (IC50=94.13 ± 10.54 μg/mL) than eugenol (2.28 ± 0.12 μg/mL), but lower than hesperidin (226.34 ± 4.96 μg/mL). JSE showed lowest ABTS-activity (IC50=39.20 ± 0.45 μg/mL) compared to hesperidin and eugenol (IC50= 8.10 ± 0.60 and 1.56 ± 0.03 μg/mL, respectively). The FRAP-reducing activity of JSE, hesperidin, and eugenol showed JSE was the lowest activity at highest concentration (65.46, 178.16 and 402.42 μM Fe(II)/μg) respectively). JSE showed the lowest anticollagenase activity (IC50=339.30 ± 7.87 μg/mL), anti-elastase (IC50=249.94 ± 16.51 μg/mL), and anti-hyaluronidase (IC50=269.26 ± 90.52 μg/mL) compared to hesperidin, and eugenol. Overall, JSE has low antioxidant activity compared to hesperidin and eugenol, as well as low anti-collagenase, anti-elastase, and anti-hyaluronidase activities.
