Abstract
|
|
|
Objective: This experimental study was preformed to investigate the effect of ethanol extract of Belamcandae Rhizoma (EBR) on dermal bioactive properties related to cosmeceuticals such as radical scavenging activity and depigmentation.
Methods: The free radical scavenging activity of EBR was assayed in cell free systems using 1,1-diphenyl-2-picrylhydrazyl (DPPH). Antibacterial potency was measured by the size of inhibition zone with change of volume. Cell viability was measured by MTT assay and tyrosinase activity was assessed using L-DOPA.
Results: EBR showed slightly radical scavenging activity and protected against UVB-induced cell cytotoxicity. Futhermore, EBR showed antibacterial activities on S. epidermidis and S. aureus. Although the proliferation of B16/F10 cells was decreased by EBR, necrosis was not revealed. EBR augmented tyrosinase activity and dendrite outgrowth in B16/F10 cells.
Conclusions: These results suggest that EBR has antioxidative ＆ antibacterial activities, and stimulate melanogenesis.
