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.
