Anti-wrinkle Activity of Acanthopanax senticosus Extract in Ultraviolet B (UVB)-induced PhotoagingThis study was performed to investigate anti-wrinkle effects of Acanthopanax senticosus (AS) on ultraviolet B (UVB)-induced photoaging with wrinkle formation. AS extract showed higher DPPH radical scavenging activity (3 ㎍/mL as IC??) and collagenase inhibition (1.52 ㎎/mL as IC50) than those of ascorbic acid (50 ㎍/mL and 2.17 ㎎/mL, respectively). Cell proliferation and type I pN collagen synthesis were increased by 11.4% and 96.4%, respectively, compared with non treatment control. In vivo, SKH-1 hairless mice were administrated AS 400 ㎎/㎏ for 10 weeks with UVB irradiation three times a week. After 10 weeks, a visual assessment and replica assay were performed on each mouse. According to visual assessment of close-up photos and skin replica, oral administration of A. senticosus affected on inhibition of wrinkle formation caused by UVB irradiation on the skin of mice as compared to the vehicle treated control mice. These results indicated that A. senticosus could protect skin wrinkle formation caused by collagen synthesis of fibroblast cells and photo-irradiation of UVB in hairless mice.

Cell proliferation and type I pN collagen synthesis were increased by 11.4% and 96.4%, respectively, compared with non treatment control.
