Pentacyclic triterpenes and other constituents in propolis extract from Melipona beecheii collected in Yucatan, México

ABSTRACT Thirteen pentacyclic triterpenes, methyl 3-oxours-12-en-23-oate, marsformosanone, taraxerone, β -amyrenone, α -amyrenone, lupenone, 24-methylencycloartan-3-one, moretenol acetate, β -amyrin acetate, germanicol acetate, 24-methylencycloartanyl acetate, β -amyrin, and α -amyrin were identified in a chloroform-methanol propolis extract from Melipona beecheii. Additionally, were identified in this propolis, hexadecanoic acid, methyl ester, octadecanoic acid, methyl ester and 1-triacontanol. The purification of the propolis extract was carried out using different chromatographic techniques, including vacuum liquid chromatography, gravity column chromatography and gel filtration chromatography Sephadex LH-20. The identification of the metabolites was performed using mass spectrometry.
