Özet: An investigation of n-BuOH extract of Dendrobium aurantiacum var. denneanum stems has led to the isolation of a new 8′,9′-dinor 8,4′-oxyneolignane glucoside, (–)-(7 S ,8 S )-4-hydroxy-3,3′,5,5′-tetramethoxy-8′,9′-dinor - 8,4′-oxyneolign a -7,9-diol- 7 ′-al 4-O-β-D-glucopyranoside (1), and four phenylpropanoid glycosides (2– 5 ) . The structures of the isolated compounds were elucidated by chemical and spectroscopic methods . This is the first report of norlignane from the genus Dendrobium.
