Antifungal amides from Piper arboreum and Piper tuberculatum
Phytochemistry, 2002In continuation of our study of the Piperaceae we have isolated several amides, mainly those bearing isobutyl, pyrrolidine, dihydropyridone and piperidine moieties. Bioactivity-guided fractionation of extracts from leaves of Piper arboreum yielded two new amides, N-[10-(13,14-methylenedioxyphenyl)-7(E),9(Z)-pentadienoyl]-pyrrolidine (1), arboreumine (2)

Journal of Applied Spectroscopy, 2016
The differentiation of chemical profiles from Piper arboreum tissues using near infrared (NIR) spectrometry and principal component analysis (PCA) was addressed. The NIR analyses were performed with a small quantity of dried and ground tissues. Differences in the chemical composition of leaf, stem, and root tissues were observed.

ABSTRACT The chemical composition of the leaf oils of Piper arboreum var. latifolium and P. hispidum were analyzed by a combination of GC/MS, 13C-NMR and Kovats indices. The main constituents found in the oil of P. hispidum were γ-cadinene (25.13%), camphene (15.61%), γ-guaiene (11.47%) and γ-elemene (10.88%). The oil of P. arboreum var.
