A tetrahydrofuran lignan as well as the known tetrahydrofuran lignan, (-)-g
randisin, and five phenylpropanoid derivatives were isolated from Piper sol
msianum. Their structures were determined by means of spectral analyses, in
cluding 2D NMR techniques such as NOE-DIFF and HMBC (3)J(C-H). (C) 2000 Els
