摘要: 新建HPLC双波长同时测定松柏苷、紫丁香苷、东莨菪内酯、滨蒿内酯及香豆素含量的分析方法。采用Shiseido CAPCELL PAK MG Ⅱ C18柱(250 mm×4.6 mm,5 μm)分析柱;使用乙腈-水为流动相,梯度洗脱;流速为0.8 mL/min;紫外检测器260 nm,315 nm双波长检测。结果显示,五种成分在测定范围内有良好的线(r2>0.999);在三个加标浓度下方法回收率为98.7%~102.5%之间,相对标准偏差(RSD)小于2.5%。该方法用于8种石斛品种含量的测定。

Abstract: A new method for simultaneous determination of cedarin,syringin,scutellarin,scoparone and coumarin was developed.The method was analyzed by Shiseido CAPCELL PAK MG II C18 column (250 mm × 4.6 mm,5 μm) ,and with a gradient solvent system of water-acetonitrile.The flow was set at 0.8 mL/min.The UV detection was set with double wavelengths of 260 nm and 315 nm.The method was validated and found to be satisfactorily linear (r2> 0.999).Recoveries ranged from 98.7% to 102.5% for all compounds at three different spiking levels and relative standard deviation (RSD) was with 2.5% or less.The established method was successfully used for evaluating the quality in eight kinds of Dendrobium.

Key words: Dendrobium, phenylpropanols, coumarins, HPLC
