Five new phenylpropanol derivatives, called morinins GP (1-5), along with t
wo known compounds, 3, 4-dimethoxycinnamylalcohol methyl ether (6) and p-me
thoxycinnamaldehyde (7), have been isolated from the roots of the medicinal
Chinese plant, Morina chinensis. The structures of all the new compounds w
ere determined on the basis of spectral evidence, especially by 2D-NR IR an
d HREIMS. Alkaline hydrolytic degradation confirmed the structure of compou
nd 5.
