From extraction of valuable compounds to health promoting benefits of olive leaves through bioaccessibility, bioavailability and impact on gut microbiota
Abstract Background The beneficial effects of olive leaves are known from ancient times. In this regard, both the olive leaves and the different preparations obtained from them (e.g. infusions, extracts) have been traditionally used for the treatment of various diseases or to alleviate the symptoms associated with different pathologies. In addition, the use of olive leaves extracts as nutraceuticals along today's continuous usage in cosmetics and medicine is common. Scope and approach Most of the health-related benefits of olive leaves have been associated to their high content in antioxidant bioactive compounds such as polyphenols, carotenoids, etc., being oleuropein and hydroxytyrosol som…
Impact of ultrasound-assisted extraction and solvent composition on bioactive compounds and in vitro biological activities of thyme and rosemary
Mediterranean herbs, specially thyme and rosemary, are important ingredients in food preparation and more recently have been studied as natural sources of bioactive compounds. This study aimed to study the effect of matrix (thyme vs. rosemary), and extraction protocol (conventional extraction vs. ultrasound assisted extraction) solvent composition (water vs. 50:50 ethanol:water solution) on the extraction of high value compounds (phenolic compounds, flavonoids and carotenoids) and also explore the antioxidant, antimicrobial (Listeria innocua, Staphylococcus aureus, and Salmonella enterica), probiotic (Lactobacillus casei and Bifidobacterium lactis), and anti-inflammatory activities. The phe…
