The present study deals with the extraction of dye from Red sanders (Pterocarpus santalinus) wood by chloroform and ethanol solvents using response surface methodology (RSM) technique. Through RSM using three-level three-factor Box-Behnken Design, the optimal conditions such as extraction temperature, time, and feed ratio were identified to be affecting extraction efficiency. The best predicted yield of dye with chloroform solvent extraction was 17.9% at 35°C, 105 minutes, feed ratio 200 mL.g-1 while experimental yield was 17%. Similarly for ethanol solvent extraction 24.36% was the predicted yield at 65°C, 105 minutes and feed ratio of 200 mL.g-1 while experimental yield was found to be 23%.
