摘要

This study aimed to optimize the extraction conditions of Russula vinosa, an edible and medicinal mushroom, to enhance its biological activity. The effects of extraction parameters (temperature, time, and ethanol-water ratio) were evaluated using Response Surface Methodology (RSM) and Artificial Neural Network-Genetic Algorithm (ANN-GA) approaches. The results showed that ANN-GA optimization yielded extracts with improved antioxidant properties, reflected by higher FRAP (193.010 mg TE/g), TAS (6.439 mmol/L), and DPPH (159.927 mg TE/g) values, along with lower TOS (11.074 µmol/L) and OSI (0.172) compared to RSM. In addition, ANN-GA extracts exhibited stronger anticholinesterase activity and enhanced antiproliferative effects. Chemical profiling revealed that ANN-GA optimization resulted in higher levels of key phenolic compounds, including gallic acid, quercetin, caffeic acid, and fumaric acid, indicating improved extraction efficiency. Overall, these findings demonstrate that ANN-GA provides a more effective optimization strategy than RSM by enhancing both bioactive compound recovery and biological activity. This study highlights the potential of R. vinosa as a valuable natural resource for functional food and pharmaceutical applications.
