Study on the Lignan Constituents in Seeds of Nandina Domestica Thunb.

OBJECTIVE To study the chemical constituents of the seeds of Nandina domestica Thunb. METHODS The compounds were isolated by a variety of column chromatography and the structures of these compounds were elucidated by means of spectral analysis. RESULTS Seven lignans were isolated and their structures were identified as syringaresinol (1), pinoresinol (2), medioresinol (3), 1-hydroxypinoresinol (4), gentioluteol (5), berchemol (6), berchemol-4'-O-β-D-glucoside (7), respectively. CONCLUSION Compounds 1-7 are isolated from this plant for the first time.
