“…HPE is also characterized as being environmentally friendly and having great potential in the food and pharmaceutical industries [ 13 ]. In recent years, HPE has been used for the extraction of carotenoids, ginsenosides, phenolic acids, flavonoids, anthocyanins, among others, from a diversity of food products, such as fruit, vegetables, food by-products, and herbs [ 14 , 15 ]. Concerning the use of HPE as a technology to extract bioactive compounds in savory, an optimization study was performed previously [ 16 ], and it was possible to obtain three sets of optimal conditions, depending on what one would want to extract: (i) for optimization of extraction yield and antioxidant activity (by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay), it was obtained a set of optimal conditions of 500 MPa, 20 min, 0% ethanol; (ii) total phenolic compounds, total flavonoids, antioxidant activity (by 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assay), and antioxidant activity (by ferric reducing antioxidant power (FRAP) assay) were optimized for 348 MPa, 20 min, 35% ethanol; and (iii) extraction of pigments (chlorophylls and carotenoids) was optimized for extraction at 500 MPa, 1 min, 70% ethanol [ 16 ].…”

Satureja montana L. has several biological properties related to its diverse composition of secondary metabolites. Nevertheless, it has been mainly studied for its essential oil, with only a few studies on the profile and bioactivities of the bioactive compounds from its leaf extracts being reported. This work aimed to study the antioxidant activity (by oxygen radical absorbance capacity (ORAC) assay), antimicrobial minimum inhibitory and bactericidal concentrations (MIC and MBC) determination, antibiofilm (by colorimetry), impact upon DNA (anti- and pro-oxidant assay), and cytotoxicity (by cell metabolism viability assays) of S. montana extracts obtained by high-pressure-assisted extraction (HPE). The extract obtained at 348 MPa, 35% (v/v) ethanol presented the highest concentration of individual phenolic compounds, and a minimum bactericidal concentration of 20 mg/mL against Listeria monocytogenes. HPE extracts showed antioxidant activity not only in ORAC but they were also able to prevent/attenuate peroxide-induced damage upon DNA. Moreover, on its own, HPE extract induced less oxidative damage than the control extract. Concerning the cytotoxicity, HPE extracts (at 0.5 and 1.0 mg/mL) were not harmful to HT29 cell lines, while control extracts (obtained at atmospheric pressure) at higher concentrations (>1.0 mg/mL) slightly reduced the metabolism of the cells. Finally, all extracts showed inhibition of the viability of 3 cancerous cell lines (>2.0 mg/mL for Caco-2, HeLa, and TR146) to below 15%.

Plant essential oils are natural and aromatic compounds that are found in small amounts in plants and have many interesting applications as flavors and fragrances in perfumery, cosmetics, pharmaceutical, food, agriculture, industry and etc. Essential oils can be produced by various techniques including conventional, novel and biotechnology methods. can be considered as a good alternative to conventional methods due to short extraction time, higher efficiency and quality, non-degradable compounds due to heat, no pollution and etc. Recently, due to the limitations and disadvantages of methods of extraction from intact plants, scientists have been trying to move their way to biotechnology methods and make a variety of plant aromatic compounds by microorganisms. In the biotechnology method, there is no any concern about factors such climate conditions, supply shortages, natural disasters, plant diseases and etc. and a product with very high efficiency and quality is obtained.

“…Los materiales herbales contienen importantes componentes bioactivos, cuyo aislamiento y purificación se da mediante la extracción como un primer paso de recuperación, descrito como un fenómeno de transporte donde los componentes de interés en la matriz son transferidos a un disolvente adecuado a lo que se busca obtener (Moreira, Alexandre, Pintado & Saraiva, 2019).…”

El presente trabajo, es una revisión que muestra el impacto que tiene el uso de las plantas medicinales en la salud humana. Desde la antigüedad, por tradición, se extendió el uso mayoritario de algunas familias vegetales como la Lamiaceae que destaca por sus propiedades aromáticas y aplicación culinaria en numerosas culturas, así como en el tratamiento y prevención de una gran variedad de enfermedades y malestares. Dentro de las especies pertenecientes a esta familia se encuentra el romero (Rosmarinus officinalis), planta que ha ganado importancia en el campo de la investigación por sus diversos atributos biológicos como: antiinflamatorio, antimicrobiano, antioxidante y anticancerígeno, entre otros; resultados que debe a sus metabolitos secundarios como: el ácido carnósico, el carnosol, el ácido rosmárico y el alcanfor, entre otros más, aunado a un potencial efecto cuando es aplicado. También se mencionan algunas metodologías que buscan la extracción de los componentes biológicamente activos del romero.
