goniothalamus gracilipes/hydrocarbon

From the roots of Goniothalamus gardneri Hook f. et. Thoms (Annonaceae), we have isolated a novel epimeric pair, gardnerinin ( 1) and 34- EPI-gardnerinin ( 1'), characterized by the presence of a gamma-hydroxymethyl-gamma-lactone moiety. These compounds represent an unusual type of mono-THF

Gigantetronenin [1] and gigantrionenin [6], two new monotetrahydrofuran Annonaceous acetogenins each possessing a double bond along the hydrocarbon chain, have been isolated from the bark of Goniothalamus giganteus by the use of brine shrimp lethality for bioactivity-directed fractionation. The
