In vitro evaluation of antioxidative activities of the extracts of petals of Paeonia lactiflora and Calendula officinalis incorporated in the new forms of biobased carriers

In this study, the petals collected from peony hybrid Paeonia lactiflora "Bowl of Beauty" and Calendula officinalis L. were extracted using an ethanol-water mixture assisted with microwave ultrasonic treatment. The isolation essential oil was done by hydrodistillation as well. total phenolic flavonoids content in extracts determined their antioxidant activity evaluated. highest found for P. C. obtained ultrasound extraction (83.16 114.47 mg GA/g, respectively), while flavonoid microwave-assisted relatively high (123.48 65.29 QE/g, respectively). DPPH• ABTS•+ assay (79% 83%) ultrasound-assisted (45% 49%), respectively. To improve both types examined analytes (extracts oil), pectin biopolymer film (as a carrier) prepared process enzymatically catalysis. Optical microscopy FTIR spectroscopy used characterization materials. films, gallic acid, showed significantly increased percentage inhibition test (91% 95%, respectively) after 10 minutes. results, also, that all formulations film, modified can be successfully applied carrier ingredients.
