CRYSTAL AND MOLECULAR STRUCTURE OF A NEW QUINOLINE DERIVATIVE PROM THE CHINESE SOFT CORALS

INTRODUCTION. 7-hydroxy-8-methoxy-4（1H） quinolone（Q）, CHNO, is a new compound isolated from the Chinese soft coral, Sinularia Polydacryla. This compound has a marked effect on increasing the circulation of blood in a white mouse brain system or heart system and on alleviating the hypoxia suffeting. It could mitigate the arrhythmia caused by aconitine. Up to now, only a few structures of quinoline derivatives have been determinated by X-ray diffraction.
