目的:为《中国药典》2010年版建立连翘药材中连翘酯苷A的含量测定方法。方法:采用RP-HPLC法,ZorbaxEclipse XDB-C18色谱柱(4.6 mm×250 mm,5μm),以乙腈-0.4%冰醋酸溶液(15∶85)为流动相等度洗脱,检测波长330 nm,柱温25℃。结果:连翘酯苷A在0.202~1.515μg线性关系良好,r=0.999 8,平均加样回收率98.54%,RSD 1.1%;11批连翘样品中连翘酯苷质量分数在0.200%~1.681%。结论:经过交叉复核表明该方法简单、准确,可靠,重复性好。
Objective: To establish the method for the determination of Forsythiaside A in the Chinese Pharmacopoeia 2010 edition. Methods: The mobile phase was eluted with acetonitrile-0.4% glacial acetic acid (15:85) using Zorbax Eclipse XDB-C18 column (4.6 mm × 250 mm, 5 μm) Temperature 25 ℃. Results: Forsythoside A had a good linearity of 0.202-1.515μg with r = 0.999 8, with an average recoveries of 98.54% and RSD of 1.1%. The forsythiaside contents in 11 batches of Forsythia suspensa samples ranged from 0.200% to 1.681 %. Conclusion: The cross-check shows that the method is simple, accurate, reliable and reproducible.
