Abstract

Nineteen different carotenoids have been isolated from various harvests of Mytilus edulis (edible mussels). Besides beta,beta-carotene (occasional) these were ten acetylenic C40-carotenoids: crocoxanthin-like, anhydro-amarouciaxanthin B, 19'-hexanoyloxyisomytiloxanthin, isomytiloxanthin, alloxanthin, mytiloxanthin, amarouciaxanthin B-like, halocynthiaxanthin, pectenol-like and heteroxanthin; two acetylenic C37-carotenoids: pyrrhoxanthinol and hydrato-pyrrhoxanthinol; four C40-skeletal allenic carotenoids: 19'-hexanoyloxyfucoxanthin, fucoxanthin, 19'-hexanoyloxyfucoxanthinol and fucoxanthinol; two C37-skeletal allenic carotenoids: peridinin and peridininol. Anhydro-amarouciaxanthin B, 19'-hexanoyloxyisomytiloxanthin (minor occasional) and hydrato-pyrrhoxanthinol constitute new carotenoids. The characterization comprised TLC and HPLC behaviour, VIS spectrophotometry, 1H NMR (including full assignment of three new carotenoid end groups), CD and mass spectra, as well as chemical derivatizations. Stereochemical considerations are discussed.

摘要

从可食用贻贝紫贻贝的不同收获物中分离出了19种不同的类胡萝卜素。除了β,β-胡萝卜素（偶尔出现）外，还有10种炔属C40-类胡萝卜素：类番红花黄质、脱水异紫红质B、19'-己酰氧基异贻贝黄质、异贻贝黄质、别黄质、贻贝黄质、类紫红质B、卤海鞘黄质、类扇贝醇和杂黄质；2种炔属C37-类胡萝卜素：紫硫菌黄质醇和水合紫硫菌黄质醇；4种C40骨架的联烯类胡萝卜素：19'-己酰氧基岩藻黄质、岩藻黄质、19'-己酰氧基岩藻黄质醇和岩藻黄质醇；2种C37骨架的联烯类胡萝卜素：多甲藻素和多甲藻素醇。脱水异紫红质B、19'-己酰氧基异贻贝黄质（少量偶尔出现）和水合紫硫菌黄质醇构成了新的类胡萝卜素。表征包括薄层色谱和高效液相色谱行为、可见分光光度法、1H核磁共振（包括对三个新类胡萝卜素端基的完全归属）、圆二色光谱和质谱，以及化学衍生化。讨论了立体化学方面的问题。
