The estimation of hydroxytyrosol-tyrosol derivatives amounts in olive oils through the analysis pastes collected during malaxation is utmost relevance due to relationship with oils' health claim regarding protection blood lipids from oxidative stress. Olive were industrial extraction cv. Cobrançosa (0–60 min; 22–34 °C). Total phenolic contents pastes' extracts assessed (2800–5400 mg GAE/kg past...

Nigrosporanenes A (1) and B (2), two new cylohexene derivatives, and tyrosol (3) were isolated from the sea fan-derived fungus Nigrospora sp. PSU-F11, whereas five known compounds: 4-hydroxybenzoic acid (4), aplysiopsene D (5), 3-isochromanone (6), (-)-drimenin (7) and diketopiperazine derivative (8), were obtained from the fungus Nigrospora sp. PSU-F12. Their structures were established by spe...

Xylaramide (1), possessing potent antifungal activity towards Nematospora coryli and Saccharomyces cerevisiae, was isolated from the culture fluids of the wood-inhabiting ascomycete Xylaria longipes together with tyrosol (2), 2,5-bis(hydroxymethyl)furan (3) and 2-hexyli-dene-3-methylsuccinic acid (4). The latter has been known as a Xylaria metabolite for many years. Compounds 2 and 3 have been ...
