The aim of this study was to evaluate the influence of several extraction methods on the content of bioactive compounds of polyphenolic structure and antioxidant properties of petals from marigold flowers (Calendula officinalis). Ethanolic extracts prepared using maceration, turbo-extraction and bead-beating techniques were investigated for total phenolics, flavonoids and tannins, and antioxidant activities as measured by FRAP and DPPH assays, as well. The results showed that the highest phenolic content (1316.367...
