Glycosidic constituents from in vitro Anoectochilus formosanus

The glycosidic constituents of whole plants of Anoectochilus formosanus pro pagated by tissue culture were investigated. A new compound, 2-(beta -D-glu copyranosyloxymethyl)-5-hydroxymethylfuran, along with the known compounds, 3-(R)-3-beta -D-glucopyranosyloxybutanolide (kinsenoside), 3-(R)-3-beta -D -glucopyranosyloxy-4-hydroxybutanoic acid, 1-O-isopropyl-beta -glucopyranos ide, (R)-(+)3,4-dihydroxy-butanoic acid gamma -lactone, 4-(beta -D-glucopyr anosyloxy)benzyl alcohol, (6R,9S)-9-hydroxy-megastigma-4,7-dien-3-one-9-O-b eta -D-glucopyranoside, and corchoionoside C were isolated.
