摘要：

本文报道了 1 988年 6 - 1 2月 (结冰期 )南极长城站附近海区冰藻色素的分离、鉴定结果。探讨了该海区冰藻色素的种类组成 ,季节变化以及冰藻色素在海洋生态系中的作用。结果表明 ,该海区冰藻已分离出色素 1 5种 ,可鉴定的有 1 3种 ,分别为 :胡萝卜素 ,脱镁叶绿素 a,叶绿素 a、b、c,叶黄素 ,岩藻黄质 ,脱植基叶绿酸 a,紫黄质 ,脱镁叶绿素 c,叶绿酸 a,叶绿素 c的衍生物 ,di-adinoxanthin,二种色素未能鉴定。该海域冰藻色素具明显的季节变化。

Abstract:

This paper reports the results of isolation and identification of the pigments from ice algae in the adjacent waters (62°12.5′S, 62°14.5′S -58°57′W,58°53′W) of the Great Wall Station, Antarctica during the icing period (from June 1988--December 1988) and studies on the compostion and seasonal variations of the pigments of ice algae in that area as well as their role in marine ecosystems.The results indicate that 15 kinds of ice algal pigments have been isolated, 13 kinds been identified. They are respectively:carotene, pheophytin a, chlorophyll-a, -b, -c,lutein, fucoxanthin, chlorophyllide-a, violaxanthin, pheophorbide-a,chlorophyllin-a, derivative of chlorophyll-c(diadinoxanthin)and two kinds of unidentified pigments. There are distinct seasonal variations of ice algae pigments in that area.
