A determination method of chlorogenic acid by high performance liquid chromtograph and photodiode array detector was established. The chromatographic column, Symmetry Sheild RP18 (3.9 mm×300 mm, 5 μm), water-methanol-acetic acid (88∶12∶1.2, V/V) mobile phase with 1.0 ml/min flow rate, the detected wavelength (326 nm), and the column temperature(25 ℃) were adopted. The calibration curve of chlorogenic acid was linear under the content of 2.24～11.2 μg, the correlation coefficient was 0.999 3. The method was s...
