Glochidiolide, isoglochidiolide, acuminaminoside, and glochidacuminosides A-D from the leaves of Glochidion acuminatum MUELL.

The dimeric butenolides glochidiolide and isoglochidiolide, a new glucoside of a nitrogen-containing C, dimer, acuminaminoside, and glucosides of C, 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 C-8 glucosides by NMR spectroscopic analyses, chemical conversion, and a modified Mosher's method.
