HPLC-UV chromatogram of the RmP methanolic extract Analysis method: Separation was performed on Phenomenex Luna C18 Column (250.0 × 4.6 mm, 5 μm), samples were eluted using water (solution A) and acetonitrile (solution B) as mobile phase. Elution varied according to gradient and solution flow as follows: 0–45 min with 0–70% solvent B, flow 0.80 mL/min, injection volume was 20 μL and detection at 296 nm.
