“…A sample from Turkey (Albayrak et al, 2010) the phenolic acids profile was similar to the Portuguese sample, whereas for flavonoids some differences were found. Those authors identified flavones, such as apigenin and naringenin derivatives.…”

Moreover, the antioxidant potential of extracts of this plant (Carini et al, 2001;Albayrak et al, 2010;Barros et al, 2010) could also support the development of cosmetic/cosmeceutical products, similarly to some documented examples dealing with the encapsulation of various plant extracts and isolated compounds. For example, Harris et al (2011) studied the Ilex paraguariensis extract encapsulation in microspheres and nanoparticles of chitosan.…”

“…Although antioxidant properties of H. stoechas methanol extract (Carini et al, 2001;Albayrak et al, 2010;Barros et al, 2010) and phenolic compounds (Lavault and Richomme, 2004) have been already investigated, there are no reports neither on the hydroalcoholic extract nor on its most used form, decoction. Moreover, to the best of our knowledge, microencapsulation of such extracts has never been studied.…”

“…Lavault and Richomme (2004) and Carini et al (2001) did not 15 present quantification data on these compounds. Albayrak et al (2010) were the only authors that presented quantification data, in which the major component present was chlorogenic acid, followed by apigenin 7-glucoside. The quantities found by those authors were lower than the ones obtained herein.…”

The present work explores the antioxidant potential of Helichrysum stoechas (L.) Moench phenolic compounds for cosmetic applications involving the following steps: chemical characterization, microencapsulation and incorporation into a moisturizer.Eighteen different phenolic compounds were identified in flowering aerial parts (decoction and hydroalcoholic extract), being 3,5-O-dicaffeoylquinic acid and myricetin O-acetylhexoside the most abundant phenolic acid and flavonoid, respectively.Comparatively to the decoction form, the hydroalcoholic extract presented both higher antioxidant activity and higher phenolic content, being its lyophilized form chosen to

“…It has been shown that there is a correlation between antioxidant capacity and antibacterial activity as well as the total phenolic content of the herb extracts or essential oils (9,15). Furthermore, it has been reported that oxygenated monoterpenes have antioxidant and antimicrobial activities (2).…”

Background: Food born pathogenic bacteria are the most important agents of infections in humans, and food spoilage also results in economic losses in food industry. Objectives: The aim of this study was the evaluation of chemical components, total phenolic content, antioxidant and antibacterial activities of Artemisia dracunculus essential oil. Materials and Methods:The essential oil of Tarragon was analyzed by gas chromatography-flame ionization detector (GC-FID) and gas chromatography/mass spectrometry (GC-MS). The antioxidant activity and total phenolic content were evaluated by bleaching of β-carotene and folin ciocalteu methods, respectively. The antibacterial effect of the essential oil was inspected on seven Gram-positive and negative bacteria using the microdilution method. Results: A total of 19 compounds were identified by GC-FID and GC-MS. The main compounds were methyl chavicol (84.83%), trans-ocimene (3.86%), z-β-ocimene (3.42%), limonene (1.79%) and α-pinene (0.57%). Total phenols were 10.16 ± 0.08 mg/g Gallic acid equivalent. The essential oil showed good antioxidant activity in bleaching of β-carotene method (50 ± 1.63%). The minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) for essential oil ranged between 3.8 to 250 mg/mL, respectively. Conclusions: The essential oil of Tarragon might be replaced by synthetic antioxidant and preservatives in food industry.

The aim was to investigate the phenolic content, antioxidant capacity, and antibacterial activity of Dalmatian sage (Salvia officinalis L.) leaves collected during different vegetation periods. Separation and quantification of the individual phenols were performed by reversed-phase (RP)-HPLC coupled with a PDA (photodiode array) detector and using an internal standard, while the contents of total phenols, flavonoids, flavones, and flavonols were determined spectrophotometrically. The antioxidant properties of the sage leaf extracts were evaluated using five different antioxidant assays (FRAP, DPPH, ABTS, Briggs-Rauscher reaction, and β-carotene bleaching). The antimicrobial activity of the extracts was tested against two Gram-positive (Bacillus cereus and Staphylococcus aureus) and two Gram-negative (Salmonella Infantis and Escherichia coli) bacterial reference strains. All extracts were extremely rich in phenolic compounds, and provided good antioxidant and antibacterial properties, but the phenophase in which the leaves were collected affected the phenolic composition of the sage extracts and consequently their biological activity. The May Extract, the richest in total flavonoids, showed the best antioxidant properties and the highest antimicrobial activity. Thus, collection of the plants during May seems the best choice for further use of them in the pharmaceutical and food industry.
