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.

摘要

从水葫芦（Pistia stratiotes L.）的乙醚提取物中分离得到的物质有亚油酸、γ-亚麻酸、（12R，9Z，13E，15Z）-12-羟基-9，13，15-十八碳三烯酸、（9S，10E，12Z，15Z）-9-羟基-10，12，15-十八碳三烯酸、α-细辛脑和 24S-乙基-4,22-胆甾二烯-3,6-二酮，这些物质被发现能够抑制固体培养基中一些微藻的生长。本文讨论了 α-细辛脑对液体培养基中敏感藻株生长的毒性。
