摘 要:目的:采用HPLC高效液相色谱法对黄丝郁金和绿丝郁金中姜黄素、单脱甲氧基姜黄素、双脱甲氧基姜黄素的含量进行比较研究。方法:分别搜集10个批次的药材样品,以甲醇超声提取60 min,以YMC-Pack-ODS-A C18色谱柱(4.6 mm×250 mm,5μm)分离,流动相乙腈-0.1%甲酸溶液(45∶55),流速1.0 mL.min-1,检测波长425 nm,进行外标法定量分析。结果:姜黄素在3.516~450 mg.L-1呈良好的线性关系(r=0.999 8),平均回收率101.36%,RSD 2.62%(n=5);脱甲氧基姜黄素在2.734~350 mg.L-1呈良好的线性关系(r=0.999 9),平均回收率102.19%,RSD 2.75%(n=5);双脱甲氧基姜黄素在2.422~310 mg.L-1呈良好的线性关系(r=0.999 8),平均回收率102.86%,RSD 3.06%(n=5)。结论:文章所建立的HPLC方法可用于有效控制中药郁金的药材质量;黄丝郁金中含有姜黄素类成分,而绿丝郁金中未检测到姜黄素类成分。Objective: To develop an HPLC method for quantitative analysis of curcuminoids in Huangsi Yujin and Lvsi Yujin derived from Cucurmae Radix. Method: Ten batches of samples were collected respectively, and were extracted with methanol in ultrasonic bath for 60 min, the separation was performed on a YMC ODS-A C18 reversed column (4.6 mm×250 mm, 5 μm), the mobile phase consisted of acetonitrile and 0.1% formic acid in water (45:55), the mobile phase flow rate was 1.0 mLmin-1 and the UV detector was monitored 425 nm for quantitative analysis. Result: The linear of curcumin, demethoxycurcumin, bisdemethoxycurcumin were within 3.516-450 mgL-1 (r=0.999 8), 2.734-350 mgL-1(r=0.999 9) and 2.422-310 mgL-1(r=0.999 8) respectively. The average recoveries of curcumin, demethoxycurcumin, bisdemethoxycurcumin were 101.36% (RSD 2.62%, n=5), 102.19% (RSD 2.75%, n=5) and 102.86% (RSD 3.06%, n=5) respectively. Conclusion: The validated HPLC method could be used as quality control method for Cucurmae Radix. Curcuminoids were only detected in Huangsi Yujin, while not detected in Lvsi Yujin.
