L-carnitine calcium fumarate and its preparation and applications are disclosed in the present invention. Having good water solubility as well as better and stronger nutritious and treating functions than the corresponding inner salts, the L-carnitine calcium fumarate as proposed having the advantages of being non-hygroscopic, stable in chemical property, and suitable for oral administration. A preparing method is as follow: fumaric acid is suspended in water and calcium base is added. The resulting mixture is heated up to 70˜90° C. and kept under stirring for 2˜8 hours, and then concentrated under reduced pressure. The resulting dried substance is added into ethanol, and the mixture is vigorously stirred. The inner salt of L-carnitine is added, and the mixture is reacted for 1˜6 hours at 60˜70° C. and then cooled for 2˜8 hours. L-carnitine calcium fumarate is obtained by filtration.
本发明揭示了L-肉碱钙富马酸盐及其制备和应用。该L-肉碱钙富马酸盐具有良好的水溶性,以及比相应的内盐更好和更强的营养和治疗功能,具有非吸湿性、化学性质稳定和适宜口服的优点。其制备方法如下:将富马酸悬浮在水中,加入钙基,将得到的混合物加热至70˜90℃,并在搅拌下保持2˜8小时,然后在减压下浓缩。所得到的干燥物质加入乙醇中,强烈搅拌混合。加入L-肉碱的内盐,将混合物在60˜70℃下反应1˜6小时,然后冷却2˜8小时,通过过滤得到L-肉碱钙富马酸盐。
