Abstract:
OBJECTIVE:To optimize the harvest time of Eucommia ulmoides.METHODS:The content of Chlorogenic acid in Eucommia ulmoides harvested at different time was determined by HPLC on Kromasil-C18(250 mm?4.6 mm,5.0 ?m).The mobile phase consisted of acetonitrile-0.4% H3PO4 solution(11∶87) with a detection wavelength of 327 nm.RESU-LTS:The content of Chlorogenic acid in Eucommia ulmoides harvested during July was the highest(at 3.178%).CONCLUS-ION:July turned out to be the optimum harvest time for Eucommia ulmoides.
