Crataegus pentagyna willd. Fruits, leaves and roots: phytochemicals, antioxidant and antimicrobial potentials.

Background: The hawthorn has recently been used as a popular herbal medicine in food applications and phytotherapy, especially for the cardiovascular system.

Methods: In this study, phytochemicals were evaluated by LC-ESI-MS, GC-MS, and biological activity, including antioxidant (DPPH test) and antibacterial (broth dilution assay), in different extracts of Crataegus pentagyna fruit, leaf, and root.

Results: Globally, 49 phenolics were tentatively identified using HPLC-ESI-MS/MS in the hydro-methanolic extract of the fruit (major apigenin, caffeoylquinic acid derivative, and 4-O-(3'-O-glucopyranosyl)-caffeoyl quinic acid), 42 in the leaf (major salicylic acid, naringenin-6-C-glucoside, and naringin), and 33 in the root (major naringenin-7-O-neohesperidoside, isovitexin-2″-O-rhamnoside, and 4-O-(3'-O-glucopyranosyl)-caffeoyl quinic acid).

Investigation of physicochemical properties, antimicrobial and antioxidant activity of edible films based on chitosan/casein containing Origanum vulgare L. essential oil and its effect on quality maintenance of cherry tomato.

Edible coatings prevent physicochemical and biological food deterioration. Using bioactive compounds like essential oils can enrich films. In this study, edible films from chitosan (C), casein (Z) and oregano (OEO) were developed, and their physicochemical, barrier, antimicrobial, antioxidant, and structural properties (FTIR, SEM) were investigated.
