The antibacterial effect of Quercus salicina Blume extract was investigated and then the stability of a cream containing it best performing fraction, the ethyl acetate fraction, was evaluated. The antibacterial effect was evaluated on the skin microorganisms Staphylococcus aureus, Bacillus subtilis, Propionibacterium acnes, Escherichia coli, and Pseudomonas aeruginosa. Among the Q. salicina Blume extract fractions, the ethyl acetate fraction demonstrated the lowest minimum inhibitory concentration against S. aureus (1,200 μg/ml), B. subtilis (2,500 μg/ml), P. acnes (1,200 μg/ml) and P. aeruginosa (312 μg/ml). Therefore, a cream containing 0.25% ethyl acetate fraction of Q. salicina Blume extract was prepared and evaluated for stability. The pH, viscosity, and absorbance of the cream were measured under various temperatures (4, 20, 37, 45oC) and sun light during a 12 week period. The changes in viscosity, absorbance and pH of the cream did not change significantly during the term of the experiment when compared with a placebo cream. In addition, any change in color or odor of the cream was not observed during the 12 weeks. These results indicate that the ethyl acetate fraction of Q. salicina Blume extract has a high antibacterial effect and is stable as a cream. There is therefore some potential for its use in cosmetic materials.
