P90, E90, E80, and E70 chromatographic profiles were obtained with an HPLC system (Jasco, Tokyo, Japan) equipped with a PU‐980 pump, an UV‐1575 detector, and a degasser Populaire DP4003. Data were obtained and processed with PowerChrom 2.5 (eDaq Technologies, NZ, Australia) software and MATLAB R2019b software (MathWorks Inc., USA). Chromatographic separation was performed on a Kromasil C‐18 semi‐preparative column (8 × 250 mm) at 30°C. A gradient elution using water (A) and methanol (B) consisted of 0–3 min (99% A, 1% B), 30 min (5% A, 95% B), and 40 min (99% A, 1% B). Freeze‐dried samples (2 mg/ml) were diluted in EtOH 20% (v/v) and filtered through 0.45 µm syringe filters. Injection volume was 50 µl, detection wavelength 266 nm, and solvent flow rate 0.4 ml/min. Polyphenols content was calculated with standard molecules of phloroglucinol and resorcinol; additionally, glucose and glucuronic acid standards were injected to check for possible interference of UA and sugars (Gonçalves‐Fernández et al., 2019 (link)). To ensure the reproducibility of the assays, a minimum of four injections of each extract were carried out.
