Novel compounds isolated from the bile of male sea lampreys are described, in particular, 7&agr;,12&agr;,24-trihydroxy-5&agr;-cholan-3-one-24-sulfate and 7&agr;,12&agr;-dihydroxy-5&agr;-cholan-3-one-24-oic acid and an ELISA for detecting the compounds. The bile compounds act as pheromones which attract female sea lampreys in water to the point in the water where the compounds had been introduced. The bile compounds are useful in lamprey population management programs where it is desirable to control the locomotion and distribution of lampreys and in food operations where it enhances the efficiency of catching lampreys for food.
本文描述了从雄性海灯鱼胆汁中分离出的新型化合物,特别是 7&agr;,12&agr;,24-三羟基-5&agr;-胆烷-3-酮-24-
硫酸盐和 7&agr;,12&agr;-二羟基-5&agr;-胆烷-3-酮-24-酸,以及检测这些化合物的 ELI
SA 方法。胆汁化合物可作为信息素,将
水中的雌性海灯鱼吸引到引入化合物的
水域。胆汁化合物可用于灯鱼种群管理计划,控制灯鱼的运动和分布;也可用于食品加工,提高捕捉灯鱼作为食物的效率。
