Phenolic and lignan compounds from Stixis suaveolens

Abstract

From the leaves of Stixis suaveolens (Roxb.), ten compounds were isolated and elucidated chemical structures by using combined methods. Their structures were identified as (±)-5-methoxylariciresinol(1), (7S, 8R, 8R')-5,5'-dimethoxylariciresinol (2), (+)-dehydrodiconiferyl alcohol (3), (+)-dehydrodiconiferyl alcohol-4-O-β-D-glucoside (4), (7R,8R)-threo-guaiacylglycerol-8-O-4'-sinapyl ether 7-O-β-D-glucopyranoside (5), 3-hydroxy-2 {4-[(1E)-3-hydroxyprop-1-en-1-yl]-2 methoxyphenoxy} propyl β-D-glucopyranoside (6), coniferin (7), syringin (8), Z-coniferin (9), and dihydrosyringin (10) by comparison of their NMR, MS data with those of published literature.
