Cohibins C and D, Two Important Metabolites in the Biogenesis of Acetogenins fromAnnona muricataandAnnona nutans1
JOURNAL OF NATURAL PRODUCTS(2000)
摘要
Two new annonaceous acetogenins, cohibins C (1a) and D (1b), have been isolated by extensive chromatography of a hexane extract of Annona muricata seeds and a cyclohexane extract of Annona nutans root bark. Their structures have been established on the basis of spectral evidence (NMR, MS) and confirmed by chemical transformation into a pair of monotetrahydrofuran (mono-THF) acetogenins. The role of these compounds in the biogenesis of mono-THF acetogenins is discussed.
