P. Duret et al., ACETOGENINS FROM ANNONACEAE .31. ISOLATION AND STRUCTURE OF 3 NEW BIS-TETRAHYDROFURAN ACETOGENINS FROM THE ROOTS OF ANNONA-CHERIMOLIA, Journal of natural products, 57(7), 1994, pp. 911-916
Three new Annonaceous isoacetogenins have been isolated from a MeOH ex
tract of Annona cherimolia roots, isocherimolin-1 [1], isomolvizarin-1
[2], and isomolvizarin-2 [3], in addition to the known compounds, bul
latacinone(=isorolliniastatin-2), squamocin, and almunequin. Their str
uctures were established on the basis of nmr spectroscopic techniques.
