摘要
目的：建立红曲米中洛伐他汀的 HPLC含量测定主。方法：以乙酸乙酯－ PH3.0磷酸水溶液 (1∶ 1)为溶剂，避光，置于摇床中， 50℃， 150r.p.m速度振摇 2小时。结果：洛伐他汀浓度在 5～ 100μ g/ml范围内呈线性关系 (0.9999)，加样平均回收率为 95.28％ (RSD=2.82)。结论：该方法简便、灵敏，易操作，为红曲米的质量评价提供了一个新的实用方法。
Objective： To establish a HPLC method for determining lovastatin in red yeast rice.Method:Under yellow light,the red yeast rice was extracted with ethyl acetate－ PH3.0 phosporic acid solution(1∶ 1)in shaking bed for 2hrs,at the revolving rate of 150r.p.m. and the temperature at 50℃ . Results:The standard curve was linear in the concentration range of 5～ 100μ g/ml(r=0.9999).The average recovery rate was 95.28％ with RSD=2.8％ .Conclusion:The new and practical method could be used for quality assessment of red yeast rice.It was rapid,sensitive and precise with good reproducibility.
