Z. Jiang et Dq. Yu, NEW-TYPE OF MONO-TETRAHYDROFURAN RING ACETOGENINS FROM GONIOTHALAMUS-DONNAIENSIS, Journal of natural products, 60(2), 1997, pp. 122-125
A new type of Annonaceous acetogenin was isolated from the roots of Go
niothalamus donnaiensis. The structures of two epimeric pairs, donnaie
nin A (1) and 34-epi-donnaienin A (1'), and donnaienin B (2) and 34-ep
i-donnaienin B (2'), characterized by the presence of a gamma-(hydroxy
methyl) gamma-lactone moiety, were elucidated by spectroscopic analysi
s and chemical derivatization. Four known mono-THF acetogenins-murisol
in, isoannonacin, and a mixture of annonacin and goniothalamicin-were
also isolated.
