Background: Clitorea ternatea flowers possess various health benefits owing to their bioactive composition. However, effective extraction of bioactives is important to appropriately utilize these flowers. This work aimed to use response surface methodology, to simultaneously optimize the process parameters to obtain maximum yield of phenolics and anthocyanins along with maximum DPPH radical scavenging activity from C. ternatea flowers. Results: Central composite design was employed with four independent variables; solid: liquid ratio (XA), ethanol concentration (XB), temperature (XC), and time (XD) which were found to affect the response variables significantly and fit to the second order polynomial model. The optimum process parameters obtained were XA‐1:50(W/V), XB‐37.21%, XC‐45°C and XD‐50.75 min. The experimental values obtained based on optimum extraction parameters agreed with the predicted values. Conclusions: The findings suggest the application of optimized parameters to acquire functionally active phenolics and anthocyanins from C. ternatea flowers using ethanol and make use of them in the food and pharmaceutical industry.
