AB Propolis is a resinous vegetal exudate modified by bees, and is interesting as apreservative and potentially functional product. This work dealt with studying the commonphenolic profiles and antioxidant capacities of 13 bee propolis from different geographical areas.Both hyaluronidase and angiotensin converting enzyme (ACE) inhibitory activities were alsoassessed and related when possible with particular phenolic compounds. High performance liquidchromatography‐ultraviolet detection (HPLC‐UV) analysis showed that every propolis containedp‐coumaric acid (1.2–12.2 mg/g) and ferulic acid (0.3–11.0 mg/g). Pinocembrin, catechin, and caffeicacid phenethyl ester (CAPE) plus galangin were the main flavonoids. Antioxidant activities werehigher than 280 μmol trolox/g for trolox equivalent antioxidant capacity (TEAC), 0.099 mmol uricacid/g for radical‐scavenging effect on hydroxyl radicals, and 0.19 mg/mL for half maximalinhibitory concentration (IC50) of antioxidant activity against superoxide anion radical. Workingwith solutions of 10 mg/mL propolis, hyaluronidase inhibitory activity ranged between 0% and68.20%, being correlated to ferulic acid content. ACE inhibitory effect determined by HPLC washigher than 78%, being correlated with catechin and p‐coumaric acid. Therefore, propolis could beuseful for food, pharmaceutical, and cosmetic companies, also helping to reduce risk factors fordiseases related to oxidative damage, inflammatory processes, and hypertension. This research alsohighlights the necessity for harmonized analysis methods and the expression of results for propolis.
