Oregano as a potential source of antidiabetic agents

Abstract

Oregano is the name given to a great variety of herbs belonging mainly to the Lamiaceae and Verbenaceae botanical families. Oregano species are rich sources of phytochemicals such as phenolic compounds like rosmarinic acid, salvianolic acid, and luteolin, among others. A few articles have previously accessed some potential pharmacological bioactivities of oregano plants; however, none has focused on the antidiabetic studies. This review aims to summarize recent studies about the potential effect of phenolic compounds from oregano plant species. The reports were retrieved from electronic databases such as PubMed, Web of Science, National Center for Biotechnology Information (NCBI), and Scopus. In addition, articles related to the mentioned topics and published between 2004–2022 were selected. The results from this study show that the antidiabetic pharmacological reports of oregano phenolic compounds are mainly in vitro reports. Therefore, the diversity of oregano species yields a broad variety of phenolic constituents, where preclinical and clinical studies are strongly recommended.

Morzeddhu: A Unique Example of a Traditional and Sustainable Typical Dish from Catanzaro

“…This process is often quite long and promotes the release of a lot of bioactive principles and flavors that complete the smell and taste of the dish. The compounds most represented in the edible part of the plant (flowers, leaves, dried or fresh) are aromatic compounds such as carvacrol, timolol, eugenol, and thymoquinone, characterized by low molecular weight and phenolic hydroxyl, conferring to them volatility and antioxidant properties [ 59 , 60 , 61 ].…”

Current Evidence of Natural Products Against Overweight and Obesity: Molecular Targets and Mechanisms of Action

“…The concentration and type of polyphenols in different food products depend significantly on the origin, cultivation, environmental conditions, maturity, pre-and post-harvest, storage, and transportation. Furthermore, these compounds have been widely studied for their beneficial health effects, highlighting their antidiabetic, anticancer, and anti-inflammatory effects, among others [7][8][9].…”

Potencial antioxidante y biofuncional de suplementos alimenticios de origen botánico mediante análisis in vitro e in silico

“…Así mismo, la aparición de patologías crónicas-degenerativas se asocian estrechamente con el estrés oxidativo (OS), el cual se puede definir como un desbalance entre los antioxidantes y los oxidantes como radicales libres (FR) y especies reactivas de oxígeno (ROS), las cuales Revista Bio Ciencias 11, e1585 ISSN 2007 ocasionan un daño a macromoléculas, y desencadenan una cascada de señalizaciones involucradas con factores pro inflamatorios, que posteriormente dan origen a una gran variedad de enfermedades no transmisibles (Byrne et al, 2021;Charlton et al, 2021;Pizzino et al, 2017;Ramachandra et al, 2021;Sabbatino et al, 2021;Sies, 2020). Es por ello que una dieta equilibrada, rica en fitoquímicos y nutracéuticos puede minimizar el impacto del estrés oxidativo (Prior & Cao, 2000), ya que se ha observado que tienen la capacidad de brindar actividad antioxidante frente a los FR y ROS, además de ejercer actividad antiinflamatoria (Leyva-López et al, 2016), anticancerígena (Criollo-Mendoza et al, 2022), hipoglicémica (Gutiérrez-Grijalva et al, 2022) e hipocolesterolémica (Das et al,2022), entre otras.…”
