摘要 目的:建立RP-HPLC法同时测定清开灵注射液、板蓝根药材中尿苷、鸟苷、告依春、腺苷的含量。方法:采用Phenomenex C18(250mm×4.6mm,5μm)色谱柱,以甲醇(A)-水(B)为流动相进行梯度洗脱,柱温40℃,流速1.0mL·min-1,检测波长254nm,进样量1μL。结果:尿苷、鸟苷、(R,S)-告依春和腺苷4个成分质量浓度分别在6.54~261.6μg·mL-1(r=0.9999)、9.42~376.8μg·mL-1(r=0.9999)、7.9~316.0μg·mL-1(r=0.9999)、8.74~349.6μg·mL-1(r=0.9999)的范围内与峰面积呈良好的线性关系;方法的平均回收率(n=6)分别为102.9%、97.2%、103.1%、98.2%。结论:所建立的高效液相色谱测定法简便、准确、重复性好、专属性强,可用于清开灵注射液和板蓝根药材含量测定质量控制。 Objective: To establish an RP-HPLC method for determination of uridine, guanosine, ( R, S ) -epigoitrin and adenosine in Qingkailing Injection and root of Isatis indigotica Fort. Methods : The HPLC separation was achieved on a phenomenex C18 ( 250 mm × 4.6 mm, 5 μm ) column at 40 ℃ . The mobile phase consisted of methanol-water with gradient elution at a flow rate of 1.0 mL .min-1.The UV detection wavelength was set at 254 nm. Results : The linear ranges were 6.54-261.6 μ g .mL-1 (r=0.9999),9.42-376.8 μg .mL-1 ( r=0.9999 ), 7.9-316.0 μg .mL-1 (r=0.9999),8.74-349.6 μ g.mL-1 ( r=0.9999 ) respectively. The average recoveries ( n=6 ) were 102.9%, 97.2%, 103.1%, 98.2%, respectively. Conclusion : The method is simple, accurate and repeatable, and can be used for quality control of Qingkailing Injection and Isatis indigotica Fort.
