Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 935-942, July 2026.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

Biotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Proteomic profile of Piper tuberculatum (Piperaceae) [PDF]

Brazilian Journal of Biology, 2017
Abstract Piper tuberculatum (Piperaceae) is a species that accumulates especially amides as secondary metabolites and several biological activities was previously reported. In this article, we report a proteomic study of P. tuberculatum. Bidimensional electrophoresis (2D SDS-PAGE) and mass spectrometry (ESI-Q-TOF) were used in this study.

Molecular Insights and Repellent Efficacy of the Essential Oil and Major Compounds From Piper cyrtopodon (Miq.) C.DC (Piperaceae) Against Aedes aegypti (Linnaeus, 1762) (Culicidae)

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
The essential oil and major compounds from Piper cyrtopodon exhibit potent, long‐lasting repellent activity against Aedes aegypti mosquitoes, combined with low cytotoxicity and favorable molecular docking interactions with odorant‐binding proteins. These findings highlight its potential for the development of alternative products for bite prevention ...

Cytotaxonomy of Piperaceae

CYTOLOGIA, 1976
From a comparison of the chromosome numbers of different species, it appears that 11 is the basic number of Peperomia and 12 of Piper. Variation in the reports of chromosome number of the same species may be due to occurrence of chromosomal biotypes.The trend of evolution in the two genera (Peperomia and Piper) appear different, numerical and ...
