摘要: Abstract Two novel compounds, the lignan, (+)-2- (3,4-dimethoxyphenyl)-6-(3,4-dihydroxyphenyl)-3,7-dioxabicyclo [3,3,0]octane, and coumarin, (+)-7-(3-methyl-4-carboxybutanoxy)umbelliferone methyl ester, have been isolated from aerialparts of Melicope hayesii . The known eudesmin, kobusin, N - p -coumaroyltyramine, -methyl-2-pyrrolidinone, umbelliferone 7- (3-methylbut-2-enoxy)umbelliferone were alsoobtained. Their structures determined by extensive NMR studies.
