【摘要】 采用高效液相色谱法(HPLC)对贵州铜仁丹参基地的丹参药材进行了指纹图谱研究。实验采用ZorbaxSBC18色谱柱(5μm,4.6mmi.d.×250mm),以乙腈0.4%(体积分数)冰醋酸水溶液为流动相,乙腈的体积分数在70min内由0线性增加到40%;流速1.0mL/min;柱温25℃;检测波长254nm。以19个主要共有峰为评价指标,采用国家药品监督管理局推荐的“计算机辅助中药指纹图谱相似度计算软件”计算处理,建立了铜仁地区丹参药材的HPLC共有指纹图谱。该法操作简单,精密度、稳定性和重现性良好,有助于加强丹参药材的质量控制。更多还原

【Abstract】 The fingerprint chromatograms were established for the quality evaluation of Salvia miltiorrhiza Bge. by high performance liquid chromatography. The analysis was performed on a Zorbax SB-C 18 column (5 μm, 4.6 mm i.d.×250 mm) with acetonitrile-water (containing 0.4% (v/v) acetic acid ) (the volume fraction of acetonitrile from 0 to 40% within 70 min) as mobile phase at a flow rate of 1.0 mL/min, and at a column temperature of 25 ℃.The detection wavelength was 254 nm. The relative standard deviations of relative retention values and relative peak areas were less than 3%. The mutual fingerprint of the extract of Salvia miltiorrhiza Bge. collected from Danshen Base in Tongren City of Guizhou Province was established by using the similarity calculation software of Chinese herbal fingerprint. The method is reliable and can be helpful in effectively controlling the quality of Salvia miltiorrhiza Bge.更多还原
