- Abstract
Arbutin is found in various plant species belonging to diverse families, such as Lamiaceae, Ericaceae, Saxifragaceae and Rosaceae. It inhibits tyrosinase and has been employed as a cosmetic skin whitening agent. Pyrus anatolica, which is endemic to Turkey, is a species of plant in the Rosaceae family. It also contains arbutin like other members of the family. In this study, Analytical method was developed and optimized in order to analyze arbutin in leaves, fruits and branches of Pyrus anatolica. The response surface methodology was used for the extraction of arbutin from this endemic plant. Experimental design was performed using the Box-Behnken design, and the evaluated parameters were extraction temperature (X1), extraction time (X2) and methanol concentration (X3) for the achievement of high extraction yield of the arbutin. The optimized experimental conditions for extraction were extraction temperature of 43.72 °C, methanol concentration of 48.57% and extraction time of 39.33 min. By using this optimized conditions, the experimental yield of arbutin is 4.74%, which is well matched with the predicted yield of 4.69%. After finding optimal conditions, real sample extraction experiments were repeated 6 times and then, average with relative standard deviation was calculated. Results were appropriate for the statistical evaluation.
