Spray Drying Conditions of Antioxidant and Anti-inflammatory Polyphenols in Microcapsules of Ultrasound Assisted Extract of Salvilla (Buddleja scordioides Kunth)

“…This phenolic profile was consistent with previous studies. 8,12,5 Flavonols are a phenolic group closely related with antioxidant and anti-inflammatory processes, especially quercetin. In this sense, quercetin is an extraordinary free radical scavenger that can trap highly reactive species such as peroxynitrite and hydroxyl radicals; hence quercetin is recommended to be used in products that provide positive health effects.…”

“…Salvilla Ultrasound Assisted Extraction. Salvilla extract (SE) was obtained by ultrasound assisted extraction (UAE) according to Macı ́as-Corteś et al 12 Milled salvilla leaves were added into 200 mL of 75% ethanol at a 1:20 ratio. This mixture was set into an ice bath, and the probe (⌀ 0.5 in.)…”

“…Antioxidant Activity by ABTS, FRAP, and ORAC Assays. Antioxidant activities were performed using the ABTS, ferric reducing ability of plasma (FRAP), and oxygen radical absorbance capacity (ORAC) methods, as previously explained by Macı ́as-Corteś et al 12 Treatments were processed as described in section 2.9. All treatments were analyzed in triplicate, and the results presented as millimoles of Trolox equivalent per milligram of salvilla extract (mmol TE/mg of SE) and percentage of retention of antioxidant activity after microencapsulation (%).…”

“…9 Bioactive compounds from salvilla have been extracted by infusion 10 and acetone maceration, 5 by successive extractions with hexane, aqueous ethanol, and methanol, 11 and by ethanolic extract with ultrasound assistance (UAE). 12 ever, plant polyphenols are sensitive to light, high temperature, and oxygen; thus, microcapsules can protect them along with other isolated substances and release them when needed. 13 Microencapsulation is described as a technology of packing liquid, solids, or gaseous materials in small, coated capsules that can release their contents under specific conditions.…”
