The structure of spirilloxanthin (rhodoviolascin) was unambiguously determined by degradative and nuclear magnetic resonance spectral studies. Similar studies indicated the structures of chloroxanthin, spheroidene (“Pigment Y”), and spheroidenone (“Pigment R”); these structures have been confirmed by total syntheses.
通过降解和核磁共振谱研究清楚地确定了螺菌黄质(视紫红霉素)的结构。相似的研究表明,氯黄嘌呤,椭球体(“ Y颜料”)和椭球酮(“ R颜料”)的结构;这些结构已通过总合成得到证实。
