A butanolide and phenolics from Machilus thunbergii
摘要:
The wood and leaves of Machilus thunbergii yielded 16 components, including two new compounds. The structures of the new constituents were formulated at (3S,2E)-2-octadecylidene-3-hydroxy-4-methylenebutanolide and (+/-)-9,9'-0-diferuloylsecoisolariciresinol by spectroscopic studies and chemical transformations.
