Abstract

The results of a 2-year study of the composition and content of carotenoids of sea snails Tritia reticulata (L., 1758) living in a mixed bottom community of bivalve mollusks in the sandy zone of the upper sublittoral (depth 0–1 m) of Cossack Bay in Sevastopol are presented. The highest content of total carotenoids are detected in June (1.8–2.09 mg/100 g of wet weight); the average for both years is 1.54 mg/100 g of wet weight. In the qualitative composition of T. reticulata taken from the pastures of bivalves on sandy–silt soil, 15 free carotenoids are identified: β-carotene, echinenone, hydroxyechinenone, astaxanthin, didehydroastaxanthin, diadinoxanthin, diatoxanthin, fucoxanthin, halocynthiaxanthin, fucoxanthinol, mactraxanthin, heteroxanthin, lutein, zeaxanthin, alloxanthin, and esters of the last four carotenoids. The possibility of metabolic transformations of carotenoids is discussed.

黑海腹足类 Tritia reticulata 类胡萝卜素的组成和含量

摘要

对海螺类胡萝卜素的组成和含量进行了 2 年研究的结果Tritia reticulata (L., 1758) 活体介绍了塞瓦斯托波尔哥萨克湾上亚滨海（深度 0-1 m）沙区的双壳类软体动物混合底部群落。 6月份检测到总类胡萝卜素含量最高（1.8-2.09毫克/100克湿重）；两年的平均值为 1.54 毫克/100 克湿重。在T的定性成分中。 reticulata 取自沙质淤泥双壳类牧场，鉴定出 15 种游离类胡萝卜素：β-胡萝卜素、海胆酮、羟基海胆酮、虾青素、二脱氢虾青素、二氮黄素、二氮黄素、岩藻黄素、卤代花黄素、岩藻黄素、麦克黄质、异黄质、叶黄素、玉米黄质、四黄质和后四种类胡萝卜素的酯。讨论了类胡萝卜素代谢转化的可能性。
