Two new bioactive Annonaceous acetogenins, rollitacin (I) and rollinac
in (2), along with one known acetogenin, javoricin, were isolated from
the ethanolic extract of the leaves of Rollinia mucosa. Compounds 1 a
nd 2 exhibited selective inhibitory effects among six human solid tumo
ur cell lines. The structural elucidations of I and 2 were achieved by
various spectroscopic analyses and chemical derivatizations. (C) 1997
