Tyrosinase Inhibition Antioxidant Effect andCytotoxicityStudies of the Extracts of Cudrania tricuspidataFruit Standardized in Chlorogenic Acid.

In the present study, various extracts of . tricuspidata fruit were prepared with varying ethanol contents and evaluated for their biomarker and biological properties. The 80% ethanolic extract showed the best tyrosinase inhibitory activity, while the 100% ethanolic extract showed the best total phenolics and flavonoids contents. The HPLC method was applied to analyze the chlorogenic acid in . tricuspidata fruit extracts. The results suggest that the observed antioxidant and tyrosinase inhibitory activity of . tricuspidata fruit extract could partially be attributed to the presence of marker compounds in the extract. In this study, we present an analytical method for standardization and optimization of C. tricuspidata fruit preparations. Further investigations are warranted to confirm the in vivo pharmacological activity of . tricuspidata fruit extract and its active constituents and assess the safe use of the plant for the potential development of the extract as a skin depigmentation agent.
