- Abstract
Platinum nanoparticles (PtNPs) were synthesized by one-step green method using Eucommia ulmoides Oliver leaf extract as reducer and stabilizer. The effects of reaction conditions on the color and concentration of PtNPs were analyzed by single factor test, and the effect of PtNPs on tyrosinase activity was studied. The results showed that the color and yield of PtNPs could be controlled by changing the reaction conditions in a certain range. The suitable reaction conditions of each factor were reaction time of 60 min, reaction temperature of 90, chloroplatinic acid concentration of 3. 5 mmol/ L, Eucommia ulmoides Oliver leaf extract concentration of 10. 0 mg/ mL. Under these conditions, the average size of prepared PtNPs was (2. 27±0. 65)nm, with face-centered cubic structure and dispersed distribution. PtNPs had a strong inhibitory effect on tyrosinase activity in vitro, IC50 value was (6. 98±0. 76) μg/ mL, which significantly reduced tyrosinase activity and melanin content induced by UVB in A375 cells, and could achieve the effect of whitening skin.
