The dimeric butenolides glochidiolide and isoglochidiolide, a new glucoside of a nitrogen-containing C8 dimer, acuminaminoside, and glucosides of C8 compounds, designated glochidacuminosides A—D, were isolated from the leaves of Glochidion acuminatum. The structures of glochidionolactone and acuminaminoside were determined by X-ray analyses, and those of the remaining C8 glucosides by NMR spectroscopic analyses, chemical conversion, and a modified Mosher's method.
