Five new phenylpropanol derivatives, called morinins L-P (1-5), along with two known compounds, 3, 4-dimethoxycinnamylalcohol methyl ether (6) and p-methoxycinnamaldehyde (7), have been isolated from the roots of the medicinal Chinese plant, Morina chinensis. The structures of all the new compounds were determined on the basis of spectral evidence, especially by 2D-NMR and HREIMS. Alkaline hydrolytic degradation confirmed the structure of compound 5.

Key words Morina chinensis; Dipsacaceae; phenylpropanol derivatives; morinin L-P
