Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

open access: yesFood Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Chemical Composition, Amino Acids, Phenolic Profiles and Bioavailability of Minerals in Livingstone Potato (Plectranthus esculentus) as Affected by Different Processing Techniques

open access: yesFood Chemistry International, EarlyView.
Boiling retained the nutrients and polyphenol compounds in Plectranthus esculentus tubers better than frying or roasting. A bioavailability study showed that the phytates and oxalates in the tuber may not affect the bioavailabilities of calcium, zinc, or iron in Plectranthus esculentus tubers when eaten.

Naturally Occurring Cinnamic Acid Sugar Ester Derivatives [PDF]

open access: yesMolecules, 2016
Cinnamic acid sugar ester derivatives (CASEDs) are a class of natural product with one or several phenylacrylic moieties linked with the non-anomeric carbon of a glycosyl skeleton part through ester bonds. Their notable anti-depressant and brains protective activities have made them a topic of great interest over the past several decades. In particular
