Abstract

The seasonal dynamics of the total carotenoid content (TCC) was studied in the indigenous Black Sea bivalve mollusk Chamelea gallina (Linnaeus, 1758). The TCC dynamics showed two distinct peaks: in spring (March–May) and fall (September). The spring elevation in the TCC coincided with bloom of sea water and was accompanied by a visually detected growth of the gonads that peaked in April (1.5 ± 0.5 mg 100 g^–1). The fall elevation in the TCC, less pronounced, occurred in September (0.5 ± 0.2 mg 100 g^–1). Totally, in spring and fall samples, there were identified up to 90% of the TCC: 11 free carotenoids (β-carotene, diatoxanthin, halocinthiaxanthin, amarouciaxanthin A, fucoxanthin, heteroxanthin, mactraxanthin, alloxanthin, lutein, diadinoxanthin, zeaxanthin) and esters of the last seven carotenoids. Possible pathways of transformation of carotenoids in Ch. gallina tissues are discussed.

黑海双壳类软体动物 Chamelea gallina 中类胡萝卜素的季节性动态（Linnaeus，1758 年）

摘要

在本土黑海双壳类软体动物Chamelea gallina 中研究了总类胡萝卜素含量 (TCC) 的季节性动态(Linnaeus, 1758)。TCC 动态显示出两个明显的峰值：春季（3 月至 5 月）和秋季（9 月）。TCC 的春季海拔与海水的盛开相吻合，并伴随着肉眼检测到的性腺生长，在 4 月达到顶峰（1.5 ± 0.5 mg 100 g ^–1）。TCC 的秋季升高不太明显，发生在 9 月 (0.5 ± 0.2 mg 100 g ^–1 )。总体而言，在春季和秋季样本中，鉴定出高达 90% 的 TCC：11 种游离类胡萝卜素（β-胡萝卜素、硅藻黄质、卤代红花黄素、胭脂虫黄质A, 岩藻黄质, 异黄质, mactraxanthin, alloxanthin, 叶黄素, diadinoxanthin, 玉米黄质) 和最后七种类胡萝卜素的酯。Ch中类胡萝卜素转化的可能途径。鸡组织进行了讨论。
