From the extract of the mushroom Scarlet elf cup () (all-, 2')- plectaniaxanthin, (all-)-2'-dehydroplectaniaxanthin and a number of sterically unhindered ()-isomers of these carotenoids were isolated and partially characterized. The carotenoid composition of the Scarlet elf cup extract was determined by HPLC analysis. The structure elucidation of the isolated compounds was carried out by UV/Vis spectroscopy, H and C-NMR spectroscopy, IR spectroscopy and mass spectrometry. The NaBH-reduction of (all-)-2'-dehydroplectaniaxanthin resulted in the racemic mixture of ()- and ()-plectaniaxanthin. The isolated ()-isomers were identified by their UV/Vis spectroscopic properties.
从红菇杯菌（）的提取物中分离出了（全反式，2′-）-红菇黄质、（全反式）-2′-脱氢红菇黄质以及这些类胡萝卜素的一些空间位阻较小的（）-异构体，并对其进行了部分表征。通过高效液相色谱分析确定了红菇杯菌提取物的类胡萝卜素组成。通过紫外/可见光谱、氢和碳核磁共振光谱、红外光谱和质谱对分离出的化合物进行结构解析。（全反式）-2′-脱氢红菇黄质经硼氢化钠还原得到（）-和（）-红菇黄质的外消旋混合物。通过紫外/可见光谱性质鉴定了分离出的（）-异构体。
