Abstract:

Piper macropodum is used in Chinese folk medicine for the treatment of rheumatism, toothache, epilepsy and stomach ache. From the ethanolic extract of the viny stem of this plant five components were isolated, a new compound and four known compounds. On the basis of spectroscopic analysis (IR, UV, MS, 1HNMR and 13CNMR) the structure of this new compound was elucidated as (2E,4E)-N-isobutyl-2,4-icosadienamide (I). The other four compounds were identified as piperine (II), piperyline (III), daucosterol (IV) and beta-sitosterol (V). All of them were isolated from this species for the first time.
