从绿色微藻 Botryococcus braunii Kawaguchi-1 菌株的菌落基质中分离出两种新的类胡萝卜素，braunixanthins 1 (1) 和 2 (2)。它们的结构主要通过NMR和FABMS来阐明。 Braunixanthins 由海胆酮、烷基酚和四甲基角鲨烯衍生物通过醚键组成。这是首次在B族中检测到烷基酚衍生物的报道。 (C) 1997 爱思唯尔科学有限公司。
Two new carotenoids, braunixanthins 1 (1) and 2 (2), were isolated from the colonial matrix of the green microalga Botryococcus braunii Kawaguchi-1 strain. Their structures were elucidated mainly by NMR and FABMS. Braunixanthins are composed of echinenone, alkylphenol and tetramethylsqualene derivative by ether linkages. This is the first report on the detection of the alkylphenol derivatives in the B race. (C) 1997 Elsevier Science Ltd.
