초록

Fractional solvent extraction by organic solvents such as hexane, chloroform, ethylacetate, and butanol was carried out using 70% ethanol extract of apple flower leaves.
Biological activities including antioxidant, whitening,antimicrobial and anti-wrinkle activities were investigated and bio-active materials of the extracts were identified using GC/MSD. Among the tested solvent fractions, ethylacetate fraction showed the highest total polyphenol content (1218.94 μg/mL), and flavonoid (140 μg/mL). The DPPH radical scavenging activities was over 80% at a dry matterbased concentration of 200 μg/μL and SOD-like activity was over 90% at 50 μg/mL concentration in ethylacetate fraction that was slightly lower than of ascorbic aicd. Tyrosinase inhibition activity related to skin-whitening was over 60%by ethylacetate fraction of 100 μg/mL. As an anti-aging effect,elastase inhibitory activity was about 45% in ethylacetate fraction. Also, it showed a significantly antimicrobial activity against P. acenes. From GC/MSD analysis, a characteristic peak of high content in ethylacetate fraction was identified as kaempferol, which has been reported as a bioactive compound.
