摘要
采用反相高效液相色谱法,以Reliasil C18(4.6mm×250mm,5μm)为色谱柱,乙腈-水-三乙胺-磷酸(25:75;1:1)为流动相,在271nm检测波长的条件下,分析广西邕宁、武鸣、靖西、平果、马山、昭平、大新、那坡、扶绥、龙虎山,共10个不同产地的两面针药材中氯化两面针碱的含量。结果表明,广西区内10个不同产地的两面针药材样品中,氯化两面针碱的含量为0.36%~1.03%,含量差异比较大,其中以邕宁(1.03%)、靖西(0.71%)、马山(0.69%)、武鸣(0.67%)等地的含量较高,昭平(0.36%)、那坡(0.44%)等地的含量较低。该方法测定两面针中氯化两面针碱的平均回收率为97.55%,RSD为1.15%(n=6)。
Determined by RP-HPLC and Kromasil ( 250mm × 4.6mm, 5μm ) column, using Acetonitrile-water-triethylamine-phosphoric acid (25 : 75 : 1 : 1) as mobile phase and UV detector wavelength is 271nm to analyze and compare the content of Nitidine chloride in Zanthoxylum nitidum (Roxb.)DC. in 10 different growing areas of Guangxi including Yongning, Wuming, Jingxi, Pingguo, Mashan, Zhaoping, Daxin, Napo, Fusui and Longhushan. The result shows that in these 10 differnt growing areas,the content of Nitidine chloride in Zanthoxylum nitidum (Roxb.) DC. is of great difference ranging between 0.36 % - 1.03 %. The areas such as Yongning (1.03 % ), Jingxi (0. 71%), Mashan (0. 69% ), Wuming (0. 67 %) are with higher content but the areas such as Zhaoping(0.36 %),Napo(0.44%) are with lower content. In this way,it had been mensurated the average recovery was 97.55%, RSD = 1.15% ( n = 6).
