New alloaromadendrane, cadinene and cyclocopacamphane type sesquiterpene derivatives and bibenzyls from Dendrobium nobile.
Five new sesquiterpene glycosides with alloaromadendrane, cadinene and cyclocopacamphane type aglycones, one new cyclocopacamphane type sesquiterpene, two new bibenzyls and eight known compounds have been obtained from stems of Dendrobium nobile Lindl. Their structures were determined on the basis of 1D, 2D NMR and HR-MS analyses and chemical methods.
