说明书摘要	The present invention relates to compounds of quinolyl organic germanium ester having the following Formula 1 and the synthesis methods thereof. R₁and R₂are defined in the specification. Organic germanium acyl chloride and 8-hydroxylquinoline were used as the starting raw materials. Displacement reaction was carried out at 0-40 DEG C., followed by hydrolysis reaction and then by changing the solvent, water soluble quinolyl organic germanium ester was finally obtained. The quinolyl organic germanium ester possesses better water solubility and fat solubility. Due to the existence of both drug active group (organic germanium part) and drug recognizing group (quinoline part) in the structure of the quinolyl organic germanium ester, the compound is expected to develop a novel kind of anti-tumor dru
