Two new phenylpropanoids, (E)-3-(3,4-dimethoxyphenyl)-2-propen-1-yl (Z
)2-[(Z)-2-methyl-2-butenoyloxymethyl]butenoate [1], and (E)-3-(4-metho
xyphenyl)-2-propen-1-yl (Z)-2-[(Z)-2-methyl-2-butenoyloxymethyl]buteno
ate [2], were isolated from the n-hexane extract of the leaves of Bupl
eurum fruticosum. Their structures were established by spectral method
