从中国南海软珊瑚Sinularia polyaotyta分离出一种新的喹啉酮衍生物(Quinolone derivative,I),分子量191.0587,分子式C_(10)H_9NO_3,由各类光谱及X光衍射分析等证实其结构为7-hydroxy-8-meth-oxy-4(IH)-quinolone,是一种新的物质。
A new Quinolone derivative (I) with molecular weight of 191.0587 and molecular formula of C_ (10) H_9NO_3 was isolated from the soft coral Sinularia polyaotyta in the South China Sea. Its structure was confirmed by various types of spectra and X-ray diffraction analysis. -hydroxy-8-meth-oxy-4 (IH) -quinolone, is a new substance.
