摘要
目的研究洛伐他汀原料药的制备工艺及质量控制方法。方法采用超临界CO2流体萃取,95%乙醇超声洗涤进行分离纯化,HPLC进行含量测定。结果超临界CO2萃取洛伐他汀的萃取率达97.17%,超声洗涤后洛伐他汀的纯度达98%以上。HPLC检测洛伐他汀的检测限为0.248~1.24μg(r=0.999 7);平均回收率为98.32%,RSD=1.98%。结论该制备工艺稳定、可行,检测方法准确、可靠,可用于洛伐他汀的质量控制。
Objective To study the preparation and quality control method of lovastatin bulk drug. Methods The supercritical CO2 fluid extraction was adopted. 95% ethanol ultrasonic washing was used for separation and purification. HPLC was applied for the content determination. Results With the supercritical CO2 fluid extraction,the extraction rate of lovastatin was 97.17%. The purification of lovastatin with ultrasonic washing was up to over 98%. The detection limit of HPLC was 0. 248 - 1.24 μg(r = 0. 999 7 ) , the average recovery was 98.32% and RSD = 1.98%. Conclusion This preparation is stable and feasible. The detection method is accurate and reliable and can be used for the quality control of lovastatin.
