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, (-)-(7S, 8S)-4-hydroxy-3,3', 5,5'-tetramethoxy-8', 9'-dinor-8,4'-oxyneoligna-7,9-diol-7'-al 4-O-beta-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.
