Abstract:
A new phenyldihydronaphthalene-type lignan, (3 R, 4 S)-6-hydroxy-4-(4-hydroxy- 3-methoxyphenyl)-5,7-dimethoxy-3,4-dihydro-2-naphthaldehyde-3 a - O - β - d -glucopyranoside (1), and a new phenylnaphthalene-type lignan, 6,7,4′-trihydroxy-3′-methoxy-2,3- cycloligna-1,4-dien-2 a, 3 a -olide (2), along with 10-known lignan derivatives (3 – 12) were isolated from the aerial part of Vitex negundo var. heterophylla. Their structures were established by comprehensive 1D- and 2D-NMR spectroscopic analyses.
