A process for a reactive separation of organic molecules from biomass includes a reaction step for the biomass, a simultaneous extraction step using a solvent, and a filtration step to recover products, wherein the products comprise ferulic acid and/or coumaric acid. The products are extracted from the biomass in a pressurized stirred batch reactor using a liquid extraction solvent and a base in which the ferulate and the coumarate remain.

A method of making artepillin C in propolis includes the following steps: A. Mix propolis with ethanol to obtain a propolis-ethanol extract; B. Provide supercritical carbon dioxide and the propolis-ethanol extract to a chromatographic column to separate wax and artepillin C, and then remove the wax at a bottom of the chromatographic column and collect the artepillin C containing isolate at a top of the chromatographic column; and C. Test the artepillin C by a cytotoxicity test, a cell morphology analysis, a cell cycle and apoptosis test, and a cell motility metastasis test to find an anti-cancer effect of the artepillin C containing isolate.
