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.

动物的类胡萝卜素。32. 贻贝(可食用贻贝)类胡萝卜素。

从不同收获的贻贝中分离出19种不同的类胡萝卜素。除了β、β -胡萝卜素(偶有)外，还有十种乙基c40类胡萝卜素:类鳄黄素、无水amarouci黄素B、19′-己烯氧基异菌黄素、异菌黄素、四氧黄素、mytilox黄素、类amarouci黄素B、卤绿黄素、果烯醇类和异质黄素;两种乙炔c37 -类胡萝卜素:吡黄嘌呤和水合吡黄嘌呤;四种c40 -骨架型allenic类胡萝卜素:19′-己烯氧基岩藻黄素、岩藻黄素、19′-己烯氧基岩藻黄素和岩藻黄素;两种c37 -骨骼allenic类胡萝卜素:橄榄素和橄榄醇。无水amarouci黄素B, 19'- hexanoyloxyisomytiloxan黄素(少量偶然)和水合pyroxanthinol构成了新的类胡萝卜素。表征包括TLC和HPLC行为，VIS分光光度法，1H NMR(包括三个新的类胡萝卜素端基的完整分配)，CD和质谱，以及化学衍生化。讨论了立体化学方面的考虑。
