Abstract
Sterically hindered cis-carotenoids 1 and 2 were isolated from seeds of the oriental bitter sweet, Celastrus orbiculatus. Their structures were determined to be (3'Z, 5'Z)-celaxanthin and (3'Z, 5'Z)-torulene, respectively, on the basis of spectroscopic data and iodine-catalyzed stereomutation. This is the first report on carotenoids with a 3Z, 5Z configuration.
摘要
从南蛇藤种子中分离出了空间位阻型顺式类胡萝卜素1和2。根据光谱数据和碘催化的立体异构化，确定它们的结构分别为(3'Z, 5'Z)-南蛇藤黄素和(3'Z, 5'Z)-玉米黄质。这是关于具有3Z, 5Z构型类胡萝卜素的首次报道。
