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.
