title: [Agglutinating and immobilizing activity of an ethanol extract of Bursera fagaroides on human and other mammalian spermatozoa].
abstract: Human spermatozoa and those obtained from mouse epididymis incubated in ethanolic from mouse epididymis incubated in ethanolic extracts of the cortex of Bursera fagaroides became agglutinated and immobilized in 100% with 30% of viability decrease. This double effect occurred in 50% of pig'ssperm and 50% of rabbit sperm when the concentration was increased tenfold. The pattern of progressive motility was affected 80% of rat's spermatocytes without agglutination. The values remained the same when the extracts were partially purified with salts of Zn++ and Ba++ or by filtration in a sephadex g-10 column. Analysis with thin layer chromatography of both purified extracts produced 3 compounds in comparison with the ethanolic unpurified extract. The extract of the plant Bursera fagaroides contains 3 compounds, which apparently are glycosides with a potent activity upon agglutination -immobilization and a low effect upon spermatocytes viability, which might be used as contraceptives .
