Aim: The aim of the
present study was to investigate the antioxidant, anti-melanogenic and
anti-wrinkle activity of Glycyrrhiza uralensis (G. uralensis)
for cosmeceutical application.
free radical scavenging activity of 1,3-butylene glycol (1,3-BG) extract of G.
uralensis was analyzed using 1,1-diphenyl-2-picrylhydrazyl (DPPH),
2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and oxygen
radical absorbance capacity (ORAC) assays. The anti-melanogenesis and
anti-wrinkle effects of G. uralensis extract were also analyzed by
tyrosinase, zymography and collagen assays.
EC50 of 1,3-BG extract of G. uralensis, determined by DPPH and
ABTS assays, was 0.59% and 1.17%, respectively.The ORAC value of the extract
was 41.56 μM trolox equivalent. The G. uralensis extract
inhibited in vitro mushroom tyrosinase activity with an IC50 of
0.6%, and it also reduced melanin contents in mouse melanoma cells. In
addition, the G. uralensis extract notably inhibited matrix
metalloproteinase-2 activity via zymography. Approximately, 60%
collagen production enhancement was observed upon treatment with the extract,
suggesting its anti-wrinkle potential. ?????
1,3-BG extract of G. uralensis may be utilized as a cosmeceutical
ingredient, offering anti-oxidant, brightening and anti-wrinkle effects.
