Phenolic compounds as modulators of gut microbiota composition: an in vitro bat...

The human diet comprises a variety of bioactive compounds, such as phenolic compounds which are widely present in vegetables and fruits that confer numerous health benefits.1 However, the health benefits of these compounds appear to be directly influenced by a number of factors, including their bidirectional relationship with gut microbiota,1,2 as these compounds are metabolized by these microorganisms, and, si...

Exploring the bioaccessibility and intestinal absorption of major classes of pu...

The bioaccessibility and bioavailability of phenolic compounds (PC) influence directly their role in disease prevention/control. Studies have evaluated this ability through complex plant and food matrices, which may reflect more a synergistic effect of the matrix than the ability of the PCs, hindering their individual exploitation in nutraceutical or pharmaceutical applications. In the present study ten pure PC...

Gut microbiota modulation induced by pure phenolic compounds: an in vitro fecal...

Exploiting the Integrated Valorization of Eucalyptus globulus Leaves: Chemical ...

E. globulus leaves have been mainly exploited for essential oil recovery or for energy generation in industrial pulp mills, neglecting the abundance of valuable families of extractives, namely, triterpenic acids, that might open new ways for the integrated valorization of this biomass. Therefore, this study highlights the lipophilic characterization of E. globulus leaves before and after hydrodistillation, aimi...

An integrated green process for the extraction of triterpenic acids fromEucalyp...

In this study the viability of the integrated exploitation of E. globulus leaf essential oil and triterpenic acids was evaluated through the development of a novel extraction process that can be implemented sequentially in a biorefinery context. Thus, essential oil (EO) collected by hydrodistillation was used for the first time as a bio-based solvent to recover triterpenic acids (TTAs) from the residue resultin...

Exploring the bioavailability of phenolic compounds through in vitro simulated ...

Conclusions: Studied phenolic compounds did not undergo enzymatic digestion after INFOGEST, as we did not detect any resultant metabolites. Bioaccessibility percentages determined after the intestinal digestion phase showed that most of the studied phenolic compounds were about 50% bioaccessible. Absorption rates of all studied phenolic compounds were high (> 80%), suggesting that they can be absorbed into the ...

Metabolism of phenolic compounds by human gut microbiota: insights from in vitr...

Screening of different phenolic compounds classes bioavailability and bioaccess...

Introduction: For centuries, plants have been seen by humans as an essential source of food or natural healthcare products.1 In an effort to improve consumers health' and well-being, much effort is being centered on the exploitation of their biological activities.2 Phenolic compounds are secondary metabolites with a huge structural diversity and widely distributed in the plant kingdom, and thus, commonly presen...

Chemical characterisation, antioxidant and antibacterial activities of Pinus pi...

Agroforestry by-products have gained rising attention in recent years as they represent inexpensive and abundant raw materials that are a source of added-value chemicals, e.g., for food and pharmaceutical applications, as well as for bioenergy generation. Pinus pinaster Ait. bark extracts are consumed worldwide for their cardiovascular benefits, whilst the health potential of Pinus pinea L. bark has not yet bee...

Lipophilic Compounds and Antibacterial Activity of Opuntia ficus-indica Root Ex...

The chemical composition, investigated by gas chromatography-mass spectrometry, and antibacterial activity of lipophilic extractives of three varieties of Opuntia ficus-indica roots from Algeria are reported in this paper for the first time. The results obtained revealed a total of 55 compounds, including fatty acids, sterols, monoglycerides and long chain aliphatic alcohols that were identified and quantified....
