Pennyroyal and gastrointestinal cells: multi-target protection of phenolic compounds against t-BHP-induced toxicity

“…As the fragmentation (MS 3 [535 / 359] À ) observed matched with the one of ion at m/z 537, losses of DSS (À198, m/z 339 base peak) and of a carbonyl group (À44) coincident with the fragmentation observed for salvianolic acid H (SAH). 26 As for compound 13, an isomer of compound 4, it was observed a characteristic UV spectrum of caffeic acid derivatives ( Table 2). 26 As for compound 13, an isomer of compound 4, it was observed a characteristic UV spectrum of caffeic acid derivatives ( Table 2).…”

Functionalized liposomes and phytosomes loading Annona muricata L. aqueous extract: Potential nanoshuttles for brain-delivery of phenolic compounds

“…The chromatographic behavior of compound 8, as well as its UV and MS spectra (Rt 26.03 min; UV 309 nm; [M-H] − at m/z 163, MS 2 [163]: 119 (100%)) was coincident with those of p-coumaric acid standard (Ferreres et al, 2013), a compound already reported in this species (George et al, 2015).…”

Comparison of bioactivities and phenolic composition of Choerospondias axillaris peels and fleshes

“…DPPH • is a stable free radical which has an unpaired valence electron at the nitrogen atom. It is one of the most commonly used substrates to evaluate antioxidant activity . Figure A shows the DPPH • ‐scavenging activity of PP and FP.…”

“…It is one of the most commonly used substrates to evaluate antioxidant activity. 34,35 Figure 3A shows the DPPH • -scavenging activity of PP and FP. The results clearly indicated that PP had higher radical-scavenging activity than ascorbic acid and FP when the sample concentration was below 200 μg mL −1 .…”
