Highlights
Propolis, referred to as bee glue, is a red to dark brown sticky substance produced by bees and is composed of a resinous mixture of compounds (Stepanović et al, 2003; Ugur and Arslan, 2004)
The ethanolic extract of propolis obtained from Tabora displayed activity on almost all tested microorganisms (MIC 0.42 – 1.67 mg/ml) with only Pseudomonas aeruginosa being resistant to this extract
The observed minimum inhibitory concentrations (MICs) for both samples were several times higher when compared to a previous report on Tanzanian propolis (Seidel et al, 2008), where MICs ranged from 15.62 to 250 mg/l for Gram +ve bacteria
Summary
Referred to as bee glue, is a red to dark brown sticky substance produced by bees and is composed of a resinous mixture of compounds (Stepanović et al, 2003; Ugur and Arslan, 2004). These compounds are produced by bees from bee secretions, beeswax, plant exudates, and other plant parts collected from the surrounding flora (Bankova, 2005; Scazzocchio et al, 2006; Wiȩckiewicz et al, 2013). Propolis contains a variety of compounds, some of which are terpenes, flavonoids and other phenolics (Marcucci, 1995; Bankova et al, 2000).
