Maca supercritical extract significantly exhibited anti-aging activity and two active compounds were isolated from the extract. The structures were elucidated by the spectroscopic data and comparison with those reported. One structure was proposed to be n-benzyl-(9Z)-octadecenamide (1), and another was identified as n-benzylmyristamide (2). Both compounds significantly extended the replicative lifespan of K6001 yeast strain. To confirm the structure of compound 1, n-benzyl-(9Z)-octadecenamide (1) was synthesized and biological activ- ity was evaluated. The synthesized n-benzyl-(9Z)-octadecenamide (1) is identical to natural com- pound 1 from spectroscopic data and biological activity.
