| dc.description.abstract | Rosmarinic acid is the main constituent of the rosemary extract (E392), which is the only natural extract allowed in the European Union to be used as food preservative. Furthermore, rosmarinic acid has many bioactivities, namely astringent, antioxidative, anti-inflammatory, antimutagenic, antibacterial and antiviral. It is also used against dyspepsia, dysmenorrhea, rheumatic diseases and Herpes simples, among others [1]. Various techniques can be employed to extract compounds from different plant parts, including traditional extraction protocols through maceration, as also extractions assisted by microwaves and supercritical fluids, among others. In this study, four different plant species were submitted to aqueous based extractions in order to determine the best conditions to obtain the highest quantity of rosmarinic acid. Rosemary (Rosmarinus officinalis L.) was chosen due to its permission to be used in the food industry and also for its high content of rosmarinic acid. Basil (Ocimum basilicum L.), Oregano (Origanum vulgare L.), and Sage (Salvia officinalis L.) were chosen for being putative sources of natural food preservatives in the near future, having also interesting bioactivities, no toxicity and a fair amount of rosmarinic acid in relation to rosemary [2]. The three chosen aqueous extraction systems were infusion, decoction and hydroethanol extraction (80:20, v/v). All the extracts were analysed using a High- Performance Liquid Chromatography coupled to a Diode Array Detector and an Electrospray Ionization Mass Spectrometer (HPLC-DAD-ESI/MS). Table 1 shows the amount of rosmarinic acid in each extraction conditions (mg/g). It is clear that infusion and hydroethanol extractions are best suited to obtain rosmarinic acid. Infusions proved to be more suitable in the cases of rosemary and oregano, while the hydroethanol mixture extracted higher contents in basil and sage. This study highlights infusion as the most adequate extraction procedure to obtain rosmarinic acid, a compound with great interest in the food industry. | pt_PT |
