Berries, Leaves, and Flowers of Six Hawthorn Species ( L.) as a Source of Compounds with Nutraceutical Potential.

Designing new forms of food, food additives, and nutraceuticals is necessary due to the growing needs of consumers, as well as the inflammation of civilization diseases, the prevention and treatment of which can be significantly supported by dietary intervention. For this reason, this study aimed to obtain highly bioactive preparations in the form of powders from the fruits, leaves, and flowers of six species of hawthorn ( L.) using solid phase extraction (SPE).

Raspberry Pomace as a Good Additive to Apple Freeze-Dried Fruit Bars: Biological Properties and Sensory Evaluation.

This study investigated the impact of adding raspberry pomace to the phenolic content and biological properties of freeze-dried apple/raspberry bars. The bars were prepared by replacing apple puree with raspberry pomace (5-50%), and their phenolic compounds were assessed using ethanol and buffer extracts. This work also explored the potential bioaccessibility of phenolic compounds in enriched bars through a simulated digestion process (digest).

The Use of Ultra-Fast Gas Chromatography for Fingerprinting-Based Classification of Zweigelt and Rondo Wines with Regard to Grape Variety and Type of Malolactic Fermentation Combined with Greenness and Practicality Assessment.

In food authentication, it is important to compare different analytical procedures and select the best method. The aim of this study was to determine the fingerprints of Zweigelt and Rondo wines through headspace analysis using ultra-fast gas chromatography (ultra-fast GC) and to compare the effectiveness of this approach at classifying wines based on grape variety and type of malolactic fermentation (MLF) as well as its greenness and practicality with three other chromatographic methods such as headspace solid-phase microextraction/gas chromatography-mass spectrometry with carboxen-polydimethylosiloxane fiber (SPME/GC-MS with CAR/PDMS fiber), headspace solid-phase microextraction/gas chromatography-mass spectrometry with polyacrylate fiber (SPME/GC-MS with PA fiber), and ultra performance liquid chromatography-photodiode array detector-tandem mass spectrometry (UPLC-PDA-MS/MS). Principal Component Analysis (PCA) revealed that fingerprints obtained using all four chromatographic methods were suitable for classification using machine learning (ML).

Chemical Profiling, Bioactive Properties, and Anticancer and Antimicrobial Potential of L. Leaves.

The aim of this study was to assess the biological potential of the polyphenolic fraction isolated from leaves, collected in the Subcarpathian region (Poland). The phenolic profile was determined using the UPLC-PDA-MS/MS method. Biological activity was determined by evaluating the antioxidant, anticancer, antibacterial, and antifungal effects.

Phytochemical Screening and Bioactive Properties of L. Pollen.

Pollen is one of the major by-products of the walnut tree, yet it is poorly investigated. Thus, the aim of this study was to investigate the total phenolics, flavonoids, antioxidant, anticancer potential, and polyphenol profile of pollen obtained from male flowers. A total of 24 phenolic compounds were identified in pollen and all of them were reported for the first time for this raw material.

Phenolic Profile and Antioxidant, Antibacterial, and Antiproliferative Activity of L. Male Flowers.

L., walnut, is a large, long-living tree, cultivated in temperate climates around the world. It is highly appreciated for its nutritional kernels and high-quality timber.

Polyphenolic Compounds of Berry, Leaf, and Flower Extracts Affect Viability and Invasive Potential of Human Glioblastoma Cells.

contains numerous health-promoting compounds that are also proposed to have anti-cancer properties. Herein, we aimed at a contemporaneous evaluation of the effects of polyphenol-rich extracts of berries, leaves, and flowers of six species on the viability and invasive potential on the highly aggressive human glioblastoma U87MG cell line. The treatment with the extracts evoked cytotoxic effects, with the strongest in the berry extracts.
