Whitening and Anti-wrinkling Effects of Fractions from Prunus persica Flos

Abstract

In this study, the compounds of Prunus persica Flos were extracted with 70.0% acetone and were purified using a sephadex-LH-20 column chromatography. As a result, eight fractions were isolated. For whitening effects, the tyrosinase inhibitory activity was determined to be 92.2% in Fr.-8 isolated from P. persica Flos at 1.000 ppm. The melanoma cell-originated tyrosinase inhibitory effect of Fr.-8 from P. persica Flos was approximately 63.4% at 100 ppm. The inhibitory activity on melanin synthesis by Fr.-8 isolated from P. persica Flos was about 71.7% at 100 ppm concentration. For anti-wrinkling effects, the elastase inhibition activities by Fr.-5, 7 isolated from P. persica Flos were around 71.4 and 74.5% respectively at 1,000 ppm. The collagenase inhibition activity and collagen synthesis by Fr.-8 isolated from P. persica Flos was about 80.0% at 100 ppm. All these findings suggested that the fractions of P. persica Flos have great potential as cosmeceutical ingredients with whitening and anti-wrinkling effects.
