Special Issue Information

Dear Colleagues,

Plants are one of the most important sources of nutrients in human nutrition, being that their consumption is the only source of nutrient intake for many people around the world. They provide proteins, carbohydrates, lipids, vitamins, and mineral elements that are essential for the maintenance of body health. However, many plants, besides their nutritional value, also provide other bioactive ingredients, either organic or inorganic, that are recognized for their ability to counteract or to give some protection against many chronic diseases such as diabetes, cardiovascular, inflammatory, and neurodegenerative disorders.

This Special Issue intends to share with the scientific community the cutting-edge research on plant foods from terrestrial and marine origin that are more than a source of nutrients. Therefore, works focused on the chemical characterization of their bioactive ingredients, bioavailability and bioaccessibility assessment, structure–bioactivity relationships, as well as the underlying mechanisms of action though the use of the most recent in vitro and in vivo models, are welcome. Additionally, well-supported studies relating health benefits with plants consumption are also considered.

This Special Issue will accept reviews, full length articles and short communications with high-standard quality.

Marrubium vulgare L., known as horehound, is a widespread and widely known plant that is used in beer breweries and also as a traditional remedy in Tunisia. In this study, methanolic extracts of plants harvested from five different locations were investigated for their antioxidant activities using three assays (ferric reducing power, radical scavenging activity, and β-carotene-linoleic acid bleaching assay) as well as the total phenolic content. The mineral composition of the plant was also investigated concerning the following elements: Fe, Mg, Ca, Cu, Zn, Mn, K, and three heavy metals, Ni, Pb, and Cd. Marrubiin, the major bioactive diterpenoid lactone, was quantified by NMR in the samples. The essential oils were obtained by hydrodistillation, and their radical scavenging activity was investigated. The toxicity of essential oils was evaluated against Artemia salina (the brine shrimp larva). The essential oil showed a weak radical scavenging activity and low toxicity. Data obtained from the five different locations showed that the antioxidant activity, as well as the total phenolic and marrubiin content, were strongly affected by the harvest sites. The metal content in the samples showed differences with the harvest location, but there was always a great abundance of calcium, magnesium, and potassium. Full article
