The utilization and economic benefits of biomass resources can be maximized through rational design and process optimization. In this study, an innovative approach for the simultaneous extraction of essential oil and lignin from Cinnamomum camphora leaves by deep eutectic solvent (DES) and optimization of the process parameters was achieved using deep learning tools. With the water content of 40%, liquid-solid ratio of 9.00mL/g, and distillation time of 51.81min, the yields of the essential oil and lignin reached 3.15±0.02% and 9.75±0.15%, re...
