Stability of Salvia fruticosa Mill. polyphenols and antioxidant activity in a citrate-based natural deep eutectic solvent

Abstract: In a previous study, it was demonstrated that a novel deep eutectic solvent (DES), composed of lactic acid and sodium citrate dibasic at a molar ratio of 15:1 (LA-SCDB15), was a high-performing system with regard to polyphenol extraction from the medicinal plant Salvia fruticosa Mill. (Greek or Cretan sage). However, an issue of particular importance that should be addressed is the stability of the extract in this novel liquid since the information available to-date on extract stability in DES is rather limite… Show more

“…Likewise, polyphenol extracts from Moringa oleifera leaves obtained with a glycerol/sodium acetate DES displayed drastic changes after storage for 18 days, at 50 °C [30]. On the contrary, Salvia fruticosa polyphenols in extracts obtained with a lactic acid/sodium citrate dibasic DES exhibited extraordinary stability for 30 days, at 40 °C [31].…”
