Muricatenol 1, a new acetogenin, has been isolated from the seeds of Annona muricata L.. Compound 1 is a C37 acetogenin without any THF rings, with four hydroxyls and one double bond in the long aliphatic chain. The hydroxyls of 1 are located at C-4, C-10, C-18 and C-19, respectively. The vicinal diol at C-18/C-19 is threo-configuration, and the double bond at C-14/C-15 is cis-configuration.
