“…In the SFE method, as the pressure increases for a given temperature, the carbon dioxide solvent power increases; thus, larger and more polar substances can be co-extracted [22]. The pressure increases, the density, witch commands the solvating power, increases too, but slowly [23].…”

“…Supercritical fluid extraction (SFE) is an interesting technique to resolve the problem occurred by the hydrodistillation, and different study have been reported in the literature [15][16][17][18][19]. Concerning the antioxidants properties of sage [20][21][22][23] the different studies developed in the literature conclude that the top of the aerial part contribute mainly to the antioxidant activity. The aims of our study were: (i) to determine the chemical composition of essential oils of Salvia officinalis collected from Tunisia, extracted by hydrodistillation and supercritical fluid extraction (SFE); (ii) to investigate the antioxidant properties of essential oils using the DPPH free radical method [24,25]; (iii) to conclude on the capacity for the Tunisia to product essential oil from sage with the best antioxidant activity.…”

Salvia officinalis L. (Lamiaceae) is a perennial woody shrub, cultivated in theMediterranean countries, mainly to obtain dried leaves used as raw material in medicine, perfumery and food industry. The aim of this paper is to compare the antioxidant properties and the chemical composition of essentials oils obtain by two extraction process: the hydrodistillation and the supercritical carbon dioxide extraction. The hydrodistillation is a traditional process used to obtain the essential oils from the sage while the supercritical fluid extraction (SFE) is a new technology tested on this plant. The chemical composition has been investigated by the performance of GC and GC/MS, and the antioxidant properties are compared using the DPPH free radical method. In the same time the effects of the extraction parameters on the yield were analysed. The composition of the organic phase obtained by hydrodistillation and SFE methods is widely different. The major constituents of oil obtained by hydrodistillation are:

“…It is cultivated as a culinary herb and as a plant of great medicinal importance, officially listed in Pharmacopoeias of many countries throughout the world. Leaf extracts of this plant have antibacterial (Farag et al 1989), antiviral (Tada et al 1994), anti-inflammatory (Baricevic et al 2001), antihydrotic (Leung 1989) and antioxidant properties (Cuvelier et al 1994;Miura et al 2002). It has been shown that antioxidant properties of sage extracts have been attributed to their major abietane-type diterpenoids: carnosic acid (CA) and carnosol (Car) as well as rosmarinic acid (RA) (caffeoyl derivative) (Cuvelier et al 1994;Miura et al 2002).…”

Both carnosic acid and carnosol have been shown to be stronger antioxidants than synthetic antioxidants (butylated hydroxytoluene and butylated hydroxyanisole) in assays of their activity by the Rancimat method (Chen et al 1992).…”

In vitro cultures of Salvia officinalis L. as a source of antioxidant compounds

The concentrations of carnosic acid, carnosol and rosmarinic acid in different materials from differentiated (multiple shoot cultures and regenerated plants) and undifferentiated (callus and cell suspension) in vitro cultures of Salvia officinalis were determined by HPLC. The results suggested that diterpenoid (carnosic acid and carnosol) production is closely related to shoot differentiation. The highest diterpenoid yield (11.4 mg g -1 for carnosic acid and 1.1 mg g -1 for carnosol) was achieved in shoots of 10-week-old micropropagated plants. The levels were comparable to those found in shoots of naturally growing plants. Undifferentiated callus and cell suspension cultures produced only very low amounts of carnosol (ca. 0.05 mg g -1 of dry weight). In contrast, content of rosmarinic acid in callus and suspension cultures as well as shoots growing in vitro and in vivo was similar and ranged between 11.2 and 18.6 mg g -1 of dry weight.

“…Synthetic antioxidants that are commonly used have some toxic and carcinogenic effects, thus inclination to natural antioxidants is increasing (Sheng et al 2011). Natural antioxidants like green tea (Camellia sinensis), rosemary (Rosmarinus officinalis) and oak fruit (Quercus branti) are rich source of catechins, terpenoids and organic acids with potential antioxidant properties (Bhagwat et al 2003;Aguilar et al 2008;Cuvelier et al 1994;Romano et al 2009;Ghaderi et al 2012).…”

Evaluation of antioxidant interactions in combined extracts of green tea (Camellia sinensis), rosemary (Rosmarinus officinalis) and oak fruit (Quercus branti)

Green tea (Camellia sinensis), rosemary (Rosmarinus officinalis) and oak fruit (Quercus branti) are of known medicinal plants used in traditional medicine. They provide substantial antioxidant activities but the possible antioxidant interaction between them has not been studied. In the present study first the bioactive compounds from these three plants were first extracted and thereafter assayed for total phenols, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, total antioxidant capacity (TAOC) and reducing power. In addition, the antioxidant properties of the extracts individually and in combinations were evaluated in soy bean oil as food system. There was a direct relation between total phenolics and antioxidant activities of extracts. Green tea and oak fruit extracts had the highest and least activity, respectively. All three kinds of interactions (synergistic, antagonistic and additive) were observed. In soy bean oil, the only effect was antagonism but even with this effect, combined extract was significantly (P<0.05) better than butylated hydroxytoluene (BHT) and control sample. Results showed that these three natural extracts and their combination can be effectively used as a substituent of synthetic antioxidant BHT.
