中文摘要: |
目的 采用高压液相色谱法对桂枝中桂皮醛含量进行测定。方法 采用ZORBAX Eclipse XDB-C18色谱柱, 乙腈:水(32:68)为流动相, 检测波长为290 nm。结果 在检测范围0.010~0.252 μg/mL(R2=0.9996)线性良好, 平均回收率为101.17%, RSD为1.60%, 依照该种方法测定6个不同批次的桂枝中桂皮醛含量。结论 该种方法在建立的检测范围内符合中药材及相关保健品的检测要求。 |

Objective To establish an HPLC method for the determination of cinnamaldehyde in Cinnamomi ramulus. Methods The determination was analyzed by ZORBAX Eclipse XDB-C18 colomns with ace-tonitrile:water(32:68)as mobile phase. Detection was performed at 290 nm. Results The method showed a good linearity over the range of 0.010~0.252 μg/mL for cinnamaldehyde with R2=0.9996. The average recovery was 101.17% with relative standard deviation of 1.60%. Six different habitats were detected on the cinnamaldehyde content in Cinnamomi ramulus by this method. Conclusion This method is suitable for the testing requirements of Chinese herbal medicines and related health care products within a detection range. |
