Abstract

Five new lignan glycosides, (8R*,7' S*,8' R*)-5,5'-dimethoxy-7-oxolariciresinol 9'-O-beta-D-xylopyranoside (1), (7S,8R)-dihydrodehydrodiconiferyl alcohol 9-O-beta-D-apiofuranosyl-(1-->6)-O-beta-D-glucopyranoside (2), (7S*,8R*,7' S*,8' R*)-4,4'-dimethoxyhuazhongilexin 9-O-beta-D-xylopyranoside (4), (7S*,8R*,7' S*,8' R*)-4,4'-dimethoxyhuazhongilexin 9-O-alpha-L-arabinopyranoside (5), and (7S*,8R*,7' S*,8' R*)-huazhongilexin 9-O-(2-feruloyl)-beta-D-xylopyranoside (6), together with four known compounds, (7R,8S)-dihydrodehydrodiconiferyl alcohol 9-O-beta-D-glucopyranoside (3), the 9-O-beta-D-xylopyranoside of icariol A(2) (7), huazhongilexin (8), and nudiposide (9), were isolated from the leaves of Neoalsomitra integrifoliola. Their structures were determined by spectroscopic analysis and chemical methods. Compounds 2, 3, 8, and 9 showed weak anti-inflammatory activities.
