Jablonsky, Michal; Majova, Veronika; Strizincova, Petra; Sima, Jozef; Jablonsky, Jozef published an article in 2020, the title of the article was Investigation of total phenolic content and antioxidant activities of spruce bark extracts isolated by deep eutectic solvents.Recommanded Product: 111-29-5 And the article contains the following content:
Extracts from spruce bark obtained using different deep eutectic solvents were screened for their total phenolic content (TPC) and antioxidant activities. Water containing choline chloride-based deep eutectic solvents (DESs) with lactic acid and 1,3-propanediol, 1,3-butanediol, 1,4-butanediol, and 1,5-pentanediol, with different molar ratios, were used as extractants. Basic characteristics of the DESs (d., viscosity, conductivity, and refractive index) were determined All the DESs used behave as Newtonian liquids The extractions were performed for 2 h at 60°C under continuous stirring. TPC was determined spectrophotometrically, using the Folin-Ciocalteu reagent, and expressed as gallic acid equivalent (GAE). The antioxidant activity was determined spectrophotometrically by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The TPC varied from 233.6 to 596.2 mg GAE/100 g dry bark; radical scavenging activity (RSA) ranged between 81.4% and 95%. This study demonstrated that deep eutectic solvents are suitable solvents for extracting phenolic compounds from spruce bark. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Recommanded Product: 111-29-5
