Two new prenylated quinones, piperogalone (1) and galopiperone (2), and a new prenylated dihydroquinone, hydropiperone (3), were isolated from Peperomia galioides H.B.K (Piperaceae). Hydropiperone exhibited potent antiparasitic activity against three species of Leishmania.

the extracts of piper sarmentosum, a medicinal plant, are being used to prepare phytopharmaceuticals while the information about chemical kinetics of constituents of the extract is unavailable to assign precise shelf life (t90) and find optimum storage conditions of the product for patient safety, and to avoid economic repercussions of launching an unstable product. the extract was exposed to t...

Crude extracts of kava (Piper methysticum G. Forster, Piperaceae) showed good activity against ovarian tumour and leukaemia cancer cell lines. Bioassay-guided isolation resulted in the isolation of six known kava lactones and two flavokavains. The structure of the compounds were elucidated by spectroscopic techniques and by comparison with data in the literature.

Piper is a large genus in the Piperaceae family, with subgenus Ottonia having about 30 species distributed Neotropics, most of which occur Brazil (26 species). characterized by flower densely papillate, pedicellate or sessile, four stigmas, stamens and 4-ribbed fruits persistent stigmas. The recent global studies propose that all should be considered Piper. Beacause doesn’t have revisionary stu...

Background: Pepper plants belong to the Piperaceae family with many pharmacological activities. The fruits of these have been widely used traditionally for various therapies, one which is an aphrodisiac. Objective: purpose this study was determine aphrodisiac activity three pepper plants, Piper nigrum, retrofractum, and cubeba prove their traditional use. Methods: level piperin, active compound...

Unsaturated aliphatic isobutylamides from Asteraceae, Rutaceae and Piperaceae are potential agents to control schistosomiasis. Affinin (N-isobutyl-2,6,8_decatrienamide) from Heliopsis longipes has strong molluscicidal activity against Physa occidentalis (LD5e ca 100 PM) and the cercariae of the fluke. The amide has also been shown to be present in Wedelia parviceps flowers.
