Purpose: This study confirms the cosmeceutical effects of the Lindera obtusiloba (L. obtusiloba) flower and its applicability as a natural cosmetic ingredient.
Methods: After obtaining the extracts from the L. obtusiloba flower using hot water and 70% ethanol, its anti-oxidation, whitening, wrinkle improvement, and anti-bacterial properties were measured.
Results: The ethanol extracts from the L. obtusiloba flower had a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effects of 81.33% at 500 μg/mL and contained phenol and flavonoid concentrations of 152.00 and 145.27 μg/mL, respectively, which were higher than those seen in the hot water extracts. With respect to the whitening effects of the L. obtusiloba flower, the ethanol extracts suppressed tyrosinase enzyme activity by 31.00% at a concentration of 500 μg/mL. In B16F10 melanoma cells, the extracts showed excellent inhibitory effects on tyrosinase and melanin biosynthesis. Its inhibitory effects on α?melanocyte-stimulating hormone (α-MSH)-induced tyrosinase activity and melanin biosynthesis were higher than those observed using the positive control, arbutin. The measurement of procollagen synthesis confirmed the wrinkle improvement effects of the L. obtusiloba flower, with the ethanol extracts promoting a 130.00% increase in procollagen biosynthesis. The anti-bacterial effects of the L. obtusiloba flower extracts on Staphylococcus epidermidis (S. epidermidis), Staphylococcus aureus (S. aureus), and Propionibacterium acnes (P. acnes) were assessed. Here the ethanol extracts had the greatest anti-bacterial effects on S. epidermidis and P. acnes.
Conclusion: L. obtusiloba flower extracts are expected to be highly applicable as natural functional cosmetics of material having skin whitening, wrinkle improvement, and anti-bacterial effects.
