Abstract

Four new compounds, a mixture of 20,23-cis-2,4-trans-bullatalicinone (1) and 20,23-cis-2,4-cis-bullatalicinone (2), rollimusin (3), and rolliacocin (4), along with eight known acetogenins, were isolated from an ethyl acetate extract of the unripe fruits of Rollinia mucosa. The structures and stereochemistry of 1-4 were determined on the basis of spectral data and chemical evidence.
