While the study quantifies phenolic compounds using HPLC, could the authors provide more details on how compound identification was validated? Were reference standards used for all identified compounds, and were any MS or NMR techniques considered to confirm structural identities?
Additionally, the antioxidant capacity results from DPPH and FRAP assays are informative, but could the authors elaborate on whether any correlation analysis was performed between total phenolic content and antioxidant activity?
