Luo JP, Zhang ZS, Tian C, Li XM: [Determination of cinnamaldehyde in Guizhi by HPLC] . Zhongguo Zhong Yao Za Zhi. 2000 Sep;25(9):544-5.
OBJECTIVE: To establish a HPLC method for the determination of cinnamaldehyde in Guizhi. METHOD: Cinnamaldehyde was separated by a Kromasil C18 column (4.6 mm x 200 mm) with a mobile phase of acetonitrile-0.1% phosphoric acid solution (48:52) and an UV detection wavelength of 285 nm. RESULT: The calibration curve was linear in the range of 0.004-0.02 microliter.ml-1, with a correlation coefficient of 0.9996. The average recovery was 100.7%(n = 5), and RSD 0.3%(n = 6). CONCLUSION: The method is simple and accurate. |
