中文摘要：

目的：采用高效液相色谱法建立红蓼花、叶茎的特征图谱。方法：用Kromasil^TM C18柱（4．6mm×250mm，5μm），流动相甲醇-0．2％磷酸水溶液梯度洗脱，流速为1．0mL·min^-1检测波长为310nm。结果：9个不同产地药材的特征图谱具有较好的相似度，样品特征图谱相似度均在97％以上。结论：采用高效液相色谱特征图谱检测技术可有效控制红蓼花、叶茎药材的质量。

英文摘要：

OBJECTIVE To study and establish the specific chromatogram of the flower and stem of PolygoniOrientalis by HPLC. METHODS The chromatographic condition was Kromasil^TM C18 column（4. 6 mm × 250 mm, 5μm）,mobile phase was methanol and 0. 2% H3PO4, and flow rate was 1.0 mL·min^-1, detection wavelength was 310nm. RESULTS The chromatogrms the materials from of 9 different place were similar. CONCLUSION Quality of the flower and stem of Polygoni Orien talis can be controlled effectively by HPLC specific chromatograrm.
