Implication

Randomized trial evaluates skin biological activities of Dioscorea batatas extracts, suggesting protective implications.

Key Points

  • This study aims to evaluate the skin biological activities of Dioscorea batatas peel extracts and their antioxidant effects.
  • Extracts obtained using ultrasonic extraction with 70% ethanol, 95% ethanol, and ethyl acetate.
  • In vitro assays included tyrosinase, MMP-1, melanogenesis in B16F10 cells, and UVB-induced viability assays in HaCaT and HDF cells.
  • Radical scavenging activities of extracts were assessed using ABTS and DPPH methods.
  • DBP extracts inhibited tyrosinase activity and reduced melanogenesis in B16F10 cells.
  • Protected UVB-irradiated HaCaT cells by increasing their viability.
  • Restored Pro-COL1A1 expression and reduced MMP-1 levels in HDF cells under UVB exposure.
