title: In vitro algal growth inhibition by phytotoxins ofTypha latifolia L.
abstract: The ether extract ofTypha latifolia L. inhibited the growth of some microalgae. Among the substances chromatographically isolated and characterized from the ether extract, three steroids [β-sitosterol, (20S) 24-methylenlophenol, and stigmast-4-ene-3,6-dione] and three fatty acids [α- linolenic, linoleic, and an unidentified C8∶2] were found to inhibit the growth of some microalgae tested. A selective effect of these substance on blue-green algae (particularly on T 625Synechococcus leopoliensis and on T 1444Anabaena flosaquae) was observed.
