title: Four new glycosides from the stems of Dendrobium fimbriatum Hook.
abstract: Four new glucosides, named as gigantol-5-O-β-d-glucopyranoside (1), 9,10-dihydro-aphyllone A-5-O-β-d-glucopyranoside (2), ficusal-4-O-β-d-glucopyranoside (3), botrydiol-15-O-β-d-glucopyranoside (4), together with eight known compounds (5-12) were isolated from the n-BuOH extract of the stems of Dendrobium fimbriatum Hook. Their structures were elucidated by the analyses of spectroscopic data.
