Impacts of pH and Base Substitution during Deaerator Treatments of Herring Milt Hydrolysate on the Odorous Content and the Antioxidant Activity

“…This means that the volatile compounds targeted in this study would evidence no antioxidant activity. In fact, in the literature, volatile compounds described as having antioxidant potential include mainly terpenes and sulfur-containing compounds [30][31][32] and, in the present case, none of the targeted odorous compounds belonged to these groups except for methional, being a sulfur-containing compound. However, the fact that its antioxidant potential was not observed in this study could be explained by the fact that either its abundance was too low, even in the untreated HMH, or potential inhibitors could be present hindering any antioxidant activity.…”

Cytotoxic Natural Products Isolated from Cryptogramma crispa (L.) R. Br.

“…The fourteen known compounds isolated from C. crispa are: quercetin (1), quercetin 3-O-βgalactopyranoside (2), quercetin 3-O-β-glucopyranoside (3), quercetin 7-O-β-glucopyranoside (4), kaempferol 7-O-β-glucopyranoside (5), ferulic acid (6), ferulic acid 4-O-β-glucopyranoside (7), p-coumaric acid-4-O-β-glucopyranoside (8), caffeic acid (9), chlorogenic acid (10), chlorogenic acid methyl ester (11), pteroside D (12), pteroside X (13), and pterosin D (15) (Figure 2). These compounds were identified for the first time in parsley fern with using several 1D and 2D NMR spectroscopic techniques.…”

“…In the current literature, only relatively volatile compounds, including alkyl esters, fatty acids, primary alcohols, aldehydes, and alkanes, have hitherto been identified by GCMS from C. crispa [6]. Some carotenoid derivatives and shikimic acid derivatives have also been suggested to be present in this plant [7]. However, the structures of these compounds remain elusive.…”

Exposure to different light intensities affects emission of volatiles and accumulations of both pigments and phenolics in Azolla filiculoides

“…Fern species have already been reported to produce a wide variety of VOC from different biochemical pathways (Fons et al, 2018 ; Froissard et al, 2011 ; Kessler et al, 2014 ; Radhika et al, 2012 ). Nevertheless, emission of either acetylene (Zimmerman, 1985 ) or ethylene (Wong Fong San et al, 1987 ) from Azolla spp.…”
