Studies on the Chemical Constituents of Platycerium wallichii Hook.

Abstract:

Seven known compounds were jsolated from the leaves of w e um wall hi Hook．On the basis of spectroscopic analysis (UV，IR, ¹H-NMR,¹³C_NMR and MS), their structures were identified as β-sitosterol(I)，sitosteryl-3-O-β-glucoside (Ⅱ)，2-propenoicacid,3-[2,3-dihydro-2-(4-hydroxy-3-methoxyphenyl)-3-(hydroxymethyl)-7-methoxy-5-benzofuranyl]-(Ⅲ)，pinoresinol(Ⅳ)，pinomsinol-4'-O-β-D- glucoside(V), benzoic acid, 2,5-dihydroxy-,methyl ester (Ⅵ)，quercetin 3-O-β-galactopyranoside (Ⅶ )．They were all isolated from the plant for the first time． The study of chemical constituents in this plant is useful for the delimitation of generic relationships in fern classification.
