“…Herbal drugs from medicinal plants are widely incorporated in wound dressing materials to improve the healing properties [ 3 , 4 ]. Quercetin is an interesting component of the flavonoid family that is found in onions, apples, berries, tea, and tomatoes [ 5 , 6 ]. In addition, it has physicochemical features and absorption ability, is a source of dietary nutrition, and principally impacts inflammation and immunological function.…”

This study concentrated on developing quercetin/cyclodextrin inclusion complex-loaded polyvinyl alcohol (PVA) hydrogel for enhanced stability and solubility. Quercetin was encapsulated in hydroxypropyl-β-cyclodextrin (HP-β-CD) by the solvent evaporation method. The prepared quercetin/HP-β-CD inclusion complex showed 90.50 ± 1.84% encapsulation efficiency (%EE) and 4.67 ± 0.13% loading capacity (%LC), and its successful encapsulation was confirmed by FT-IR and XRD. The quercetin/HP-β-CD inclusion complex was well dispersed in viscous solutions of PVA in various amounts (0.5, 1.0, 1.5. 2.5, and 5.0% w/v ratio), and the drug-loaded polymer solution was physically crosslinked by multiple freeze–thaw cycles to form the hydrogel. The cumulative amount of quercetin released from the prepared hydrogels increased with increasing concentrations of the inclusion complex. The introduction of the inclusion complex into the PVA hydrogels had no influence on their swelling ratio, but gelation and compressive strength reduced with increasing inclusion complex concentration. The potential cytotoxicity of quercetin/HP-β-CD inclusion complex hydrogels was evaluated by MTT assay and expressed as % cell viability. The results show biocompatibility toward NCTC 929 clone cells. The inhibitory efficacy was evaluated with 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay, and the results show a higher level of antioxidant activity for quercetin/HP-β-CD inclusion complex hydrogels compared with free quercetin. The findings of our study indicate that the developed quercetin/HP-β-CD inclusion complex hydrogels possess the required properties and can be proposed as a quercetin delivery system for wound-healing applications.

The objective of this paper was to evaluate seven different berries most consumed in Romania in order to determine the bioactive compounds: total phenolics content, total flavonoid content, total anthocyanins content, antioxidant activity by DPPH and total antioxidant capacity (water-soluble and lipid-soluble by photochemiluminescence assay, PCL). The analyzed fruits contain significant amounts of phenolic compounds between 18.91 and 383.06 mg gallic acid equivalents per 100 grams of fresh berries. Black currant extract had the highest content of total phenolic compounds, 383.06 mg GAE/100g, while the lowest level was obtained for the gooseberry, 18.91 mg GAE/100g. DPPH values varied between 22.15 and 892.35μmol Trolox Equivalent/100g fresh berries. Strong positive correlations between the antioxidant capacity of lipid-soluble compounds measured by PCL and DPPH was found (r= 0.9153). The results obtained demonstrated that different Romanian berries studied show a great antioxidant activity with possible benefits on human health.
