Extraction Optimization of Phenolic Compounds from Leaves: Identification, Characterization and Antioxidant Activity.

() has attracted much attention because of the high oil content in its seeds, but there are few systematic studies on the phenolic compounds of leaves (TSP). In this study, the extraction process of TSP was optimized by response surface methodology. The phenolic components of these extracts were analyzed by high-performance liquid chromatography (HPLC).
