Elm. Dasilva et al., CORIAHEPTOCIN-A AND CORIAHEPTOCIN-B, THE FIRST HEPTAHYDROXYLATED ACETOGENINS, ISOLATED FROM THE ROOTS OF ANNONA-CORIACEA, Journal of natural products, 60(2), 1997, pp. 162-167
Two new annonaceous acetogenins, coriaheptocin A (1) and coriaheptocin
B (2), have been isolated from the roots of Annona coriacea Mart. (An
nonaceae). Heptahydroxylated, they present an unusual 1,3,6,7-tetrol a
rrangement. Determination of their structures required an original MS
and NMR strategy.
