【摘要】 建立了板蓝根注射液HPLC特征图谱。采用Waters Atlantis T3(5μm,4.6×250 mm)色谱柱,以甲醇为流动相A,水为流动相B,进行梯度洗脱;流速为0.8 mL/min;柱温为30℃;检测波长250 nm。板蓝根注射液的色谱图基本相同,检出特征共有峰有9个。该方法简便,灵敏度高,重复性好,结果准确可靠,可作为板蓝根注射液有效的鉴别和质量评价方法。更多还原

【Abstract】 To establish HPLC profile of Banlangen injection, the Waters Atlantis T3(5 μm, 4. 6 x 250 mm)column was used. With methanol as mobile phase A and water as mobile phase B, gradient elution was/min; the column temperature was 30 ℃; the detection wavelength was 250 nm. The chromatograms of Banlangen injection were basically the same. There are 9 common peaks for the detected features. This method is simple, sensitive and reproducible. The results are accurate and reliable, and can be used as an effective method for identification and quality evaluation of Banlangen injection.更多还原
