Total amounts of phenols (A), flavonoids (B), flavanols (C), hydroxycinnamic acids (D), anthocyanins (E) and reducing sugars (F), antioxidant activity (G) and specific bioactive compounds (H) detected in selected pressurized liquid extracts. Results are expressed as g of standard compound equivalent per kg of pomace dry weight (g eq/kgDW). Different letters indicate a statistically significant difference (oneway ANOVA followed by a post hoc two-tailed Student’s t-test, p < 0.05) between the same type of data. Data are the mean ± SD (n = 2). Samples: T50, wet coarse milled pomace, 50 min extraction, 75% EtOH-H₂O /CO₂ ratio; S100, wet coarse milled pomace, 30 min extraction, 100% EtOH-H₂O /CO₂ ratio; PWF, wet fine milled pomace, 30 min extraction, 75% EtOH-H₂O /CO₂ ratio; PD, dried coarse milled pomace, 30 min extraction, 75% EtOH-H₂O /CO₂ ratio. AA, ascorbic acid; CAT, catechin; cPIC, cis-piceid; EC, epicatechin; ECG epicatechin gallate; EGC, epigallocatechin; FA, ferulic acid; GA, gallic acid; GLUC, glucose; MALV, malvidin.
