|Title:||Two new neolignan glycosides from Pteris multifida Poir|
|Keywords:||Pteris multifida Poir|
neolignan glycoside, (7S, 8S)- Δ7′-2
4′-neolignan-4-O-β-D-apiofur anosyl- (1→6)-β-D-glucopyranoside
|Abstract:||Two new neolignan glycosides, named as multifidoside A 1 and B 2, together with four known compounds have been isolated from the roots of Pteris multifida Poir. The structures of multifidoside A and B have been characterized by spectroscopic and chemical means as (7S, 8S)-Δ7′-2,9′-dihydroxy-5′-methoxy-7,3′-dioxy-8,4′-neolignan-4-O-β-D-apiofuranosyl-(1→6)-β-D-gluco¬pyranoside and (7S, 8S)-Δ7′-2,9,9′-trihydroxy-7,3′-dioxy-8,4′-neolignan-4-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside. The known compounds are identified by comparing their spectral data with those of authentic samples or data reported in the literature.|
