Influence of pre-treatments on yield, chemical composition and antioxidant activity of Satureja montana extracts obtained by supercritical carbon dioxide

Chemical composition of the essential oil and headspace of Satureja montana L.

“…Oils, 2020;7(2): 22-34 Čopra-Janićijević et al DOI: 10.37929/nveo.743706 compilation on the essential oil diversity of species S. montana of various origins, it was found that chemotype A was the most prevalent among its essential oils studied to date. Thus, two isomeric monoterpene phenols -carvacrol and thymol along with two monoterpene hydrocarbons --terpinen and pcymene -appear as the main constituents in S. montana collected from different locations in Croatia as described by Milos et al (2001), Radonic & Milos (2003), Vidic et al (2009), Dunkić et al (2012), Ćavar et al (2013), as well as from Italy (Fraternale et al, 2007, Benelli et al, 2017, Caprioli et al 2019Albania (Ibrailu et al, 2011, Maccelli et al, 2020; Montenegro (Damjanović-Vratnica et al, 2011); Portugal (Santos et al, 2019); Serbia (Vidović et al, 2014), and Spain (Navarro-Rocha et al, 2020). Mediterranean and Sub Mediterranean bioclimates, moderate water stress, full flowering stage of the plant, and drying method can be critical factors that are able to enhance the percentage of carvacrol in the oil of the plants with chemotype A.…”

Effect of emergent non-thermal extraction technologies on bioactive individual compounds profile from different plant materials

“…SC-CO 2 allows the extraction of several different bioactive compounds such as those present in essential oils, flavonoids, total phenolic compounds, coumarins, and diterpenoids, from different herbal materials, such as Marchantia convoluta (Cao, Xiao, & Xu, 2007;Xiao, Chen, & Xu, 2007), rosemary (Peng et al, 2007;Topala & Tataru, 2016;Vázquez, García-Risco, Jaime, Reglero, & Fornari, 2013;Vicente et al, 2013) Table 4 Supercritical CO 2 extraction studies where an individual compound profile was determined.

Rosemary is a well-known aromatic herb used mainly for cooking, having also a variety of bioactivities, such as antioxidant and anti-inflammatory.…”

Coriander (Coriandrum sativum L.): Bioactive Molecules and Health Effects

“…Temperature and pressure of SFE system control both the composition and yield of coriander seed extract, so mild amendments in these two parameters change the density of the supercritical solvent [59]. The advantages of supercritical fluid extracts over conventional techniques include ease to remove solvent from extract, mild extracting temperatures (avoid heat damaging), and nontoxic and environment-friendly technique [82].…”
