This article is from International Journal of Molecular Sciences, volume 13.AbstractIn this work, a rapid extraction method based on ultrasound-assisted extraction UAE of syringin from the bark of Ilex rotunda Thumb using response surface methodology RSM is described. The syringin was analyzed and quantified by high performance liquid chromatography coupled with UV detection HPLC-UV. The extraction solvent, extraction temperature and extraction time, the three main factors for UAE, were optimized with Box-Behnken design BBD to obtain the highest extraction efficiency. The optimal conditions were the use of a sonication frequency of 40 kHz, 65% methanol as the solvent, an extraction time of 30 min and an extraction temperature of 40 °C. Using these optimal conditions, the experimental values agreed closely with the predicted values. The analysis of variance ANOVA indicated a high goodness of model fit and the success of the RSM method for optimizing syringin extraction from the bark of I. rotunda.
