[Study on phenylpropanoids from Dregea sinensis var. corrugata].
OBJECTIVE
To study the chemical constituents of Dregea sinensis var. corrugata.


METHODS
The chemical constituents were isolated by various column chromatographic techniques. Structures were elucidated on the basis of NMR data.


RESULTS
Eight compounds were isolated and their structures were elucidated as syringaresinol (1), syringaresinol-O-3-D-glycopyranoside (2), 3, 4'-dimethoxyl-4, 9, 9'-trihydroxyl-benzofuranneolignan-7'-ene (3), 3, 4'-di- methoxyl-4, 9-dihydroxyl-9'-hydroethyl-benzofuranneolignan-7'-ene (4), conifer-aldehyde (5), sinapic aldehyde (6), 3-hydoxy-1-(4-hydroxy-3-methoxy-phenyl)-propan-1-one (7), 3-hydroxy-1-(3-methoxy-4-hydroxyphenyl)-propan-1-one (8).


CONCLUSIONS
Compounds 1-8 were isolated from Dregea sinensis var. corrugata for the first time.
