Abstract
Chemical examination of the methanolic extract from the stem bark of Daphne aurantiaca led to the isolation of two innovanoside dimers (1 and 2) with an unusual four-membered cyclobutane ring, together with the isoinnovanoside 3. Their chemical structures and configurations were elucidated by extensive spectral analysis and synthesis.
