The isolated compounds were identified based on the physical, chemical and spectroscopic properties and comparison with data of the literatures. This is the first reported of the isolation of 3-(4’-methoxyphenylpropanoyl) pyrrole from P.sarmentosum. It was reported previously from Piper lolot C.DC., from Vietnam [

Geographical distribution, seasons, different plant parts and morphology, climate as well as ecological conditions may also influence the biosynthesis of the secondary metabolites of the plants. This is may be the reason why the chemical constituents of this species are different from the same species which were reported previously.
