摘要
目的采用高效液相色谱方法测定益脑方口服液中桂皮醛的含量。方法C18色谱柱,流动相为甲醇-水(29∶71),流速:1.0 m l.m in-1,柱温:35℃,检测波长:280 nm。结果桂皮醛回收率99.29%,RSD=0.591%。结论该法简便、灵敏、重复性好,可作为益脑方口服液中的桂皮醛含量测定方法。
Aim To determine the content of cinnamaldehyde in yinaofang oral liquid by HPLC. Methods C18 column. The mobile phase was methanol-water （29：71 ） and UV detection wavelength was set at 280 nm. The flow rate was 1.0 ml · min^-1. The column temperature was at 35℃. Results The average recovery of cinnamaldehyde was 99.29%, The RSD was 0. 591%. Conclusion The method is simple,sensitive,accurate and can be used to determine the contents of cinnamaldehyde in yinaofang oral liquid.
