The tunicates, or sea squirts, are common marine organisms that selectively accumulate metals such as V, Fe, Mo, Nb, in their blood cells. Despite the more than 70 years of interest in the compounds responsible for this accumulation, their extreme lability has eluded attempts to isolate and characterize them. The isolation and structure of the first of these blood pigments tunichrome B-1 from the Ascidia nigra is reported.
被囊动物，即海鞘，是常见的海洋生物，它们能在血细胞中选择性地积累钒、铁、钼、铌等金属。尽管人们对导致这种积累的化合物已有70多年的研究兴趣，但由于其极不稳定，一直未能成功分离和鉴定这些化合物。本文报道了从黑海鞘中首次分离出的这些血液色素之一——被囊色素B-1的结构。
