海藻中甜菜碱的研究

STUDIES ON THE BETAINES IN SEAWEED

甜菜碱是一种氨基酸或亚氨基酸的衍生物。1984年Blunden等用生物检测法测定海藻中细胞激动素的水平时,偶然发现了甜菜碱这类和细胞激动素有类似活性的化合物。目前已在两百多种海藻中发现了18种甜菜碱及3类甜菜碱脂。海藻中甜菜碱的分布十分广泛且结构多样。由于甜菜碱对植物的生长有明显的生理响应,所以被看作是海藻中的一类活性物质。

Based on the special chemical characteristics of betaines and their analogues, ion-exchange chromotography was selected to extract and separate them from marine algae. Dragendroffs reagent (KBiI4) was used to test the existence of betaines and and their analogues in marine algae. The total content of betaines from seven species was obtained by using the sediment method of Reinkeate salt. The result shows that the content of betaines in two species of Chlorophyta and two species of Rhodophyta are relatively high,the content of betaines in Enteromopha prolifera can even to 0. 9%. The content in the three species of Phaeophyta is relatively low.The total results obtained by above methods will be great value to determine how to exploit and ultilize betaines and their analogues in marine algae.
