Table 1.
Total phenolic content (TPC) and antiradical activity of mushroom extracts.
TPC expressed as mg of gallic acid equivalents per gram of dried extract; IC50 expressed as mg of dry extract per mg DPPH●; AE—antiradical efficiency (1/IC50); TE—Trolox equivalent; VCE -ascorbic acid equivalent. Equivalents were calculated by dividing extract mean IC50 by standard mean IC50. For Trolox IC50 = 0.134 mg/mg DPPH●; for ascorbic acid IC50 = 0.146 mg/mg DPPH●. Mean values of three replicate assays with standard deviations.
Table 2.
LC-ESI-MS/MS analytical results of phenolic acids investigated in mushroom extracts, including retention times, molecular masses, mass-to-charge ratio (m/z) and fragments obtained with given collision energy.
Compounds confirmed by comparison with authentic standards.
Table 3.
Analytical parameters of LC-ESI-MS/MS quantitative method; data for calibration curves, limit of detection (LOD) and limit of quantification (LOQ) values for each analyzed phenolic acid.
Table 4.
Phenolic acid contents in mushroom extracts expressed in μg per g of dry weight of mushrooms.
Abbreviations: “-”not detected; Trace—trace amounts. Mean values of three replicate assays with standard deviation.
Table 5.
Antimicrobial activity of mushroom extracts expressed in mg of dry extract per ml.
Abbreviations: R—MBC/MIC ratio; “-”not determined; MICs of gentamicin ranged from 0.03–0.12 x 10–3 mg/ml and 0.25–1.0 x 10–3 mg/ml for Gram-positive and Gram-negative bacterial strains, respectively; DMSO at the final concentration used had no influence on the growth of strains. Mean values of three replicate assays.
