Abstract Phenolic compounds and antioxidant activities of peony. We investigated the phenolic compounds and antioxidant capacities of free and bound phenolics from peony which have long been consumed as Ornamental flowers and used as Pharmaceutical ingredients. Flower of peony which extract by Ethyl Acetate showed the highest value of total phenolic content (TPC) (331.6872±0.0094 µg gallic acid equivalents (GAE)/mg dry weight). Flower stalk had the highest total flavonoid content (TFC) (55.9671±0.0069 µg QE/mg dry weight). Major phenolic acids identified in these analyses were gallic acid, while predominant flavonoids were quercetin and rutin. The results of this study showed that soluble as well as bound fractions of edible flowers are rich sources of phenolic compounds with antioxidant, DPPH radical-scavenging activity and reducing power. This study has provided useful information for screening peony as potential sources of bioactive components with high antioxidant properties that may be of interest to consumers and public health workers.
