Antibacterial activity of propolis produced by Frieseomelitta varia

Abstract: To contribute to the development of antibacterial products from propolis produced by native Brazilian bees, twenty-nine samples of propolis collected from hives in the state of Minas Gerais, Brazil, were screened for in vitro activity against Aeromonas hydrophila, Bacillus subtilis, Pseudomonas aeruginosa, and Staphylococcus aureus. Among the samples from native Brazilian bees, only that from Frieseomelitta varia (Lepeletier, 1836) inhibited in vitro bacterial growth. Consequently, this propolis underwent frac… Show more

“…Compound 35 was obtained as an oil, and its molecular formula was established as C 19 H 24 O 4 on the basis of its HRESIMS ( m / z 315.1601 [M – H] − ) data. Comparison of the UV and 1 H and 13 C NMR data of 35 (Table ) with those of artepillin C ( 40 ) indicated that their structures only differed in the nature of one of the two prenyl moieties; thus, 35 comprised a hydroxydiprenylcoumaric acid derivative. Accordingly, a pair of broad singlets at δ H 4.88 and 4.99 was ascribed to the methylene hydrogens of a vinyl group, wherein the respective carbon resonances were observed at δ C 111.5 and 145.8.…”

“…36 The NMR data of 24 were thus an invaluable tool for allowing its correct identification as a 3-methoxyflavone derivative and found to be in agreement with those of 3-O-methylkaempferol, also known as isokaempferide, 41 and reported in other propolis samples. 42 Accordingly, the 1 H and 13 C NMR data of 3,4-dihydroxybenzoic acid (2), caffeic and coumaric acids (4 and 8), the dihydroflavonols 12 and 19, the flavonols 20 and 34, and the prenylated phenylpropanoids 28, 30, 31, 32, 40, 42, and 43 (Supporting Information) confirmed their identity, which was 2) with those of artepillin C (40) 43 indicated that their structures only differed in the nature of one of the two prenyl moieties; thus, 35 comprised a hydroxydiprenylcoumaric acid derivative. Accordingly, a pair of broad singlets at δ H 4.88 and 4.99 was ascribed to the methylene hydrogens of a vinyl group, wherein the respective carbon resonances were observed at δ C 111.5 and 145.8.…”
