Summary: Extrusion of hempseed hull at different barrel temperature and screw speed led to increased total phenolic content, antioxidant activities, and inhibition of α-glucosidase and acetylcholinesterase. Interaction between extrusion parameters influenced the phenolic/flavonoid content, antioxidant activities, and enzyme inhibition. Various phenylpropionamides were identified, with N-trans-caffeoyltyramine showing significant positive correlation with biological activities.

Summary: This study investigated the changes in polyphenol content during pumpkin processing and comprehensively characterized and quantified the phenolic compounds using LC-ESI-QTOF-MS/MS and HPLC-PDA. The results showed that pumpkin seeds and skins had the highest total phenolic content and total antioxidant capacity, while separated pumpkin puree had a higher total condensed tannins content. Epicatechin and catechin were found to be the most abundant phenolic compounds in pumpkin seeds and skins. This study highlights the potential of pumpkins as a source of antioxidant polyphenols.

Summary: This study comprehensively profiles the polyphenol compounds in pasture grasses, legumes and novel forages collected during successive seasons. Different forages contain varying concentrations of phenolic acids and flavonoids. Winter and spring forages exhibit higher polyphenol concentrations and antioxidant potential compared to summer samples. The decline in polyphenol concentrations in forages may be due to pasture maturity or dry climatic conditions as the season progresses.

Summary: Anthocyanins were characterized in red cabbage, sweet potato, and Tradescantia pallida leaves. Various non-, mono-, and diacylated cyanidins were identified in red cabbage. Sweet potato leaves contained mono- and diacylated cyanidin- and peonidin glycosides, while T. pallida leaves mainly contained tetra-acylated anthocyanin tradescantin. The thermal stability of red cabbage and purple sweet potato extracts surpassed that of a commercial food dye, but still fell short compared to the stability of Tradescantia extract.
