Grape Pomace Polyphenols Reduce Acute Inflammatory Response Induced by Carrageenan in a Murine Model.

Grape pomace (GP), a by-product of wine production, contains bioactive polyphenols with potential health benefits. This study investigates the anti-inflammatory properties of a polyphenolic fraction derived from GP, obtained by ultrasound-microwave hybrid extraction and purified using ion-exchange chromatography. In the inflammation model, mice were divided into six groups: intact, carrageenan, indomethacin, and three GP polyphenols treatment groups.

Polyphenolic characterisation and antiprotozoal effect of extracts obtained by maceration, ultrasound, microwave and ultrasound/microwave of (Jacq.) Cass.

(Jacq.) Cass. (Asteraceae) has antiprotozoal properties and contains extractable phenolic compounds by the maceration method (M).

Antifungal In Vitro Activity of sp. Extracts on Fungal Isolates from Tomato Crop.

Synthetic chemicals are mainly used for the control of fungal diseases in tomato, causing the phytopathogens to generate resistance to the chemical active ingredient, with a consequent risk to human health and the environment. The use of plant extracts is an option for the control of these diseases, which is why the main objective of this research was to study an alternative biocontrol strategy for the management of plant diseases caused by fungi through obtaining polyphenol extracts from mistletoe plants growing on three different tree species-mesquite (), cedar (), and oak (), which contain flavones, anthocyanins, and luteolin. The overall chemical structure of the obtained plant extracts was investigated by RP-HPLC-ESI-MS liquid chromatography.

The Ultrasound-Assisted Extraction of Polyphenols from Mexican Firecracker ( Jacq.): Evaluation of Bioactivities and Identification of Phytochemicals by HPLC-ESI-MS.

The objective of the present work was to optimize the extraction of phytochemicals from Jacq. by ultrasound-assisted extraction. Taguchi L9 orthogonal array was used to evaluate the factors solid/liquid ratio (1:8, 1:12, and 1:16), extraction time (10, 20, and 30 min), and ethanol concentration (0, 35, and 70%).

The secondary metabolites from Beauveria bassiana PQ2 inhibit the growth and spore germination of Gibberella moniliformis LIA.

Fungal secondary metabolites with antimicrobial properties are used for biological pest control. Their production is influenced by several factors as environment, host, and culture conditions. In the present work, the secondary metabolites from fermented extracts of Beauveria bassiana PQ2 were tested as antifungal agents against Gibberella moniliformis LIA.

Procyanidins: From Agro-Industrial Waste to Food as Bioactive Molecules.

Procyanidins are an important group of bioactive molecules known for their benefits to human health. These compounds are promising in the treatment of chronic metabolic diseases such as cancer, diabetes, and cardiovascular disease, as they prevent cell damage related to oxidative stress. It is necessary to study effective extraction methods for the recovery of these components.

Phytochemical Characterization of and subs. as Mexican Mistletoe Plants with Antimicrobial Activity.

In Mexico, mistletoes have several applications in traditional medicine due to the great variety of compounds with biological activities that have not been characterized to date. The goals of the present study are to analyze the composition of minerals and phytochemical compounds in Mexican mistletoes and subs. qualitatively and quantitatively, identify the compounds using HPLC-MS, and assess the antimicrobial potential in phytopathogenic microorganism control.

Antibacterial Potential by Rupture Membrane and Antioxidant Capacity of Purified Phenolic Fractions of Leaf Extract.

The present research focused on evaluating the antibacterial effect and the mechanism of action of partially purified fractions of an extract of . Furthermore, both its antioxidant capacity and composition were evaluated. The extract was fractionated by vacuum liquid chromatography.

Effect of ultrasound treatment on the extraction of antioxidants from Kunth fruits and identification of phytochemicals by HPLC-ESI-MS.

The influence of ultrasound-assisted extraction of phytochemicals from Kunth on the antioxidant capacity was investigated. The factors evaluated were: ultrasound extraction time (10, 20 and 30 min), ethanol concentration (0, 35, 70 %) and solid/liquid ratio (1:4, 1:8 and 1:12 g mL). The L (3) array was applied, and the DPPH scavenging capacity of treatments was evaluated to obtain optimal extraction conditions.

Production of fatty acid methyl esters and bioactive compounds from citrus wax.

Citrus wax is a waste generated during the purification process of the citrus essential oil. A lot of citrus wax wastes are globally produced, despite this, its composition and properties are not well known. Here we present comprehensive results proving the chemical composition and the physical properties of citrus wax.

Screening and characterization of medicinal plants extracts with bactericidal activity against .

The aim of the present study was to perform a screening of extracts obtained from 15 medicinal plants using water (at 25 and 90 °C) or ethanol (at 25 °C), to bactericidal activity against cariogenic ATCC 25175, as well as to carry out the preliminary phytochemical characterization of the extracts and HPLC/MS assay for selected extracts. The extractions were carried out for 5 h at 400 rpm. Only five from 45 tested extracts were selected based on their antibacterial activity.

Effect of different polyphenol sources on the efficiency of ellagic acid release by Aspergillus niger.

Fungal hydrolysis of ellagitannins produces hexahydroxydiphenic acid, which is considered an intermediate molecule in ellagic acid release. Ellagic acid has important and desirable beneficial health properties. The aim of this work was to identify the effect of different sources of ellagitannins on the efficiency of ellagic acid release by Aspergillus niger.
