Abstract:

This research was aimed to study the whitening effect and mechanism of Zhuang medicine Poecilobdella manillensis extract. MTT method was used to detect the inhibitory effect of Poecilobdella manillensis extract on the proliferation of melanoma cells (B16). Spectrophotometry was used to detect the effect of Poecilobdella manillensis extract on TYR activity and melanin synthesis in B16 cells, and the scavenging ability of DPPH, ·OH and ·O2- free radicals and the total antioxidant capacity were also detected. Based on an ultraviolet-irradiated nude mice skin pigmentation model, Masson Fontana silver staining was used to show the distribution of melanin in skin, and the levels of TYR, SOD, MDA, α-MSH, bFGF, NGF, IL-1α, TNF-α and IFN-γ in serum were also measured. The results show that the IC50 of B16 cells proliferation are 230.66, 109.70, 53.18 μg/mL after Poecilobdella manillensis extract treatment at 24, 48 and 72 h, respectively. The IC50 of arbutin at 24, 48 and 72 h are 1.11, 1.40 and 1.30 times higher than those of Poecilobdella manillensis extract, respectively. The non-cytotoxic concentration of Poecilobdella manillensis extract could significantly increase the tyrosinase activity and melanin content of B16 cells. The Poecilobdella manillensis extract has strong antioxidant ability in vitro. The IC50 of DPPH, ·OH and ·O2- free radicals are 0.37, 0.38 and 0.43 g/L, respectively. The total antioxidant capacity of 0.8 g/L Poecilobdella manillensis extract is equivalent to 1.0 g/L vitamin E. Poecilobdella manillensis extract could significantly reduce the number of melanocytes in skin of nude mice, increase the content of SOD in serum, decrease the contents of MDA, α-MSH, bFGF, NGF, IL-1α, TNF-α and IFN-γ and TYR activity. Zhuang medicine Poecilobdella manillensis extract has a good whitening effect, and its mechanism may be related to the inhibition of tyrosinase activity and antioxidation capacity.

Key words: Poecilobdella manillensis, whitening effect, melanoma cells, tyrosinase, antioxidant
