Punicalagin‐enriched edible coatings from revalorized pomegranate peels for quality enhancement of fresh‐cut celery

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Pomegranate peel is a rich source of phenolics, particularly punicalagin, but its valorization for fresh produce preservation requires stabilization. This study aimed to develop and evaluate freeze‐dried encapsulates of pomegranate peel extracts as ingredients in edible coatings for fresh‐cut celery. Pomegranate peels were extracted

Variability in Foliar Ellagitannins of Hippophaë rhamnoides L. and Identification of a New Ellagitannin, Hippophaenin C

Journal of Agricultural and Food Chemistry, 2018
Berries of common sea-buckthorn (Hippophaë rhamnoides L.) are well-known and used for their bioactive components, and while there is a considerable amount of research on the leaves as well, their ellagitannins (ETs) have not been a prominent focus of research. We identified and quantified ten major hydrophilic polyphenols, all ETs, in H.

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

Phytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Ellagitannins and Flavan-3-ols from Raspberry Pomace Modulate Caecal Fermentation Processes and Plasma Lipid Parameters in Rats

Molecules, 2015
Raspberry pomace is a source of polyphenols, which nutritional and health promoting properties are not sufficiently known. The aim of this 8-weeks study was to scrutinize if raspberry extracts (REs) with different ellagitannins to flavan-3-ols ratios ...

Enzymatic oxidation of ellagitannin and a new ellagitannin metabolite from Camellia japonica leaves

Tetrahedron, 2017
Abstract Polyphenols in the leaves of Camellia japonica L. at different stages of growth were analyzed by HPLC. Pedunculagin [2,3; 4,6-bis-( S )-hexahydroxydiphenoyl- d -glucose] was the major polyphenol in the youngest leaves. The levels of this compound and (+)-catechin decreased as the leaves matured.
