산벚나무는 장미과에 속하는 것으로, 수피인 화피의 radical 소거능과 항염증 효과가 보고되고 있어, 이를 이용하여 화장품 원료로 이용하고자 생리활성을 검증하였다. 전자공여능은 에탄올추출물 500 ppm에서 92%의 효능을 보여 열수추출물 59% 보다 우수하였고, SOD 유사활성의 경우 열수추출물 1,000 ppm에서 에탄올추출물의 경우는 50%의 활성능을 나타내었다. xanthine oxidase 저해능은 500 ppm의 농도에서 열수추출물의 경우 40%, 에탄올추출물의 경우 60%의 저해능을 나타내었다. 지방산패 억제능 측정의 경우 $Cu^{2+}$에 의한 저해 효과는 열수추출물보다 에탄올추출물의 효과가 높았으며, $Fe^{2+}$에 의한 저해 효과는 열수와 에탄올추출물 모두 500 ppm에서 80% 이상의 저해능을 보였다. 피부미백과 관련된 tyrosinase 저해능의 경우 1,000 ppm에서 열수추출물의 경우는 26%, 에탄올추출물의 경우 20%의 저해능을 보였다. 항염증과 관련된 hyaluronidase 저해능의 경우 500ppm에서 에탄올추출물의 경우 96%의 효능을 보였다. 산벚나무 수피추출물의 피부상재균인 Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli 및 Propionibacterium acne에 대한 저해환형성을 관찰한 결과 열수추출물보다 에탄올추출물의 효능이 더 우수하였다.
Prunus sargentii R. of Rosaceae familiy, has been reported to have radical scavenging activity and anti-inflammatory effect. On these facts, biological activity and safety test were conducted to evaluate biological activities of the extracts of P. sargentii R. as a potential pharmaceutical ingredient. The electron donating ability of its ethanol extracts at a 500 ppm level showed 92%, which was higher than that of hot water extract (59%), the superoxide dismutase (SOD)-like activity of the water extract of P. sargentii R. was about 50%, the ethanol extract of P. sargentii R. was about 40% at 1,000 ppm concentration. Xanthine oxidase inhibition by the water extract of P. sargentii R. was about 40% and that by the ethanol extract was 60% respectively at 500 ppm concentration. From the measurement on lipid oxidation, the $Cu^{2+}$ chelating effect of the ethanol extract was higher than that of hot water extract. The $Fe^{2+}$ chelating effect was also shown to be about 80% at a 500 ppm concentration in both hot water extract and ethanol extract. The tyrosinase inhibition effect related to skin-whitening was 26% by hot water extract and 20% by ethanol extract respectively at a 1,000 ppm. Hyaluronidase inhibition activity related to the anti-inflammation effect was 96% in ethanolic extract at a 500 ppm. Clear zones formed by P. sargentii R. against the human skin-resident micro-flora such as Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Propionibacterium acnes indicated that antimicrobial activity of the ethanol extract was higher than that of the hot water extract.
