Phenolic composition and antioxidant activity of propolis from various regions of Poland

Abstract

The aim of this work was to determine phenolic acid and flavonoid contents, as well as antioxidant properties of propolis from different regions of Poland. Total phenolic content of propolis samples ranged from 150.05 to 197.14 mg/g GAE, while total flavonoid content was 35.64-62.04 mg/g QE. The dominant phenolic acid was p-coumaric acid, the content of which was from 37.54 to 116.95 mg/g. The samples also contained much ferulic acid. Among the flavonoids, chrysine and galangine were dominant, and for two samples, naringine was dominant. The propolis samples exhibited various antiradical activity measured towards DPPH(·) (1.92-2.69 mM TE/g) and ABTS(·+) (3.96-4.98 mM TE/g) and reducing power was determined by the ferric reducing antioxidant power method (6.23-9.19 mM Fe(II)/g). The significant linear correlations between total phenolic content and antiradical activity and between total phenolic content and reducing power were observed. Moreover, the total flavonoids content significantly correlated with antiradical activity and reducing power.

FTIR analysis and quantification of phenols and flavonoids of five commercially available plants extracts used in wound healing

“…The herbal with the highest amount of flavonoids among the products studied is Propolis from UK, 35mg Q / g of propolis dry extract. The amount of flavonoids in UK propolis is in the range of flavonoids found in samples from Poland [43]. Brazilian propolis presents fewer amounts of flavonoids than the UK one, which could be confirmed by the FTIR.…”

“…104, l. [41][42][43][44] [1]), healing "involves platelet aggregation and blood clotting, formation of fibrin, an inflammatory response to injury, alteration in the ground substances, angiogenesis and re-epithelialization". To heal, the wound / the burn needs to be free of infection.…”

Components responsible for antimicrobial activity of propolis from continental and Mediterranean regions in Croatian

“…A high correlation between the total phenolic and flavonoid content and free radical scavenging activity was also reported for propolis samples from other countries; e.g., Argentina (Vera et al 2011), Japan (Hamasaka et al 2004), Greece and Cyprus (Popova et al 2005), and Poland (Socha et al 2015). Correlations between individual compounds and antioxidant and antimicrobial activity were also analysed ( Table 4).…”

“…TPC values of these samples was between 10.94 and 79.23 mg GAE/g propolis. 30 TPC and TFC values of propolis extracts have been reported that as 174.7 mg GAE/g dry sample, 45.1 mg QE/g dry sample from China, 31 between 150-197 mg GAE/g dry sample, 35.64-62.04 mg QE/g dry sample from Poland, 32 and 31.2-299 mg GAE/g dry sample, 2.5-176 mg QE/g dry sample from other parts of the world, respectively.…”
