    Notes: Abstract Among the substances isolated from ethyl ether extract ofPistia stratiotes L., linoleic acid,γ-linolenic acid, (12R,9Z,13E,15Z)-l2-hydroxy- 9,13,15-octadecatrienoicacid, (9S,10E,12Z,15Z)-9-hydroxy-10,12,15-octadecatrienoic acid, α-asarone, and 24S-ethyl-4,22-cholestadiene-3,6-dione were found to inhibit the growth of some microalgae in solid medium. Toxicity of α-asarone on the growth of sensitive algal strains in liquid medium is discussed.

    Notes: 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.
