Four new glycosides from the stems of <i>Dendrobium fimbriatum</i> Hook

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