Abstract
OBJECTIVE: To separate the constituents from Eucommia ulmoides. METHOD: The constituents were separated by the repeated chromatography and identified by spectral methods. RESULT: The seven compounds were obtained, which were kaempferol(1), quercetin(2), astragalin(3), hirsutin(4), rutin(5), 3,4-dihydrobenzonic acid(6), ethyl glucopyranoside(7). CONCLUSION: Compounds 3-7 were obtained from leaves of E. ulmoides for the first time.
