Acaricide activity of different extracts from Piper tuberculatum fruits against Rhipicephalus microplus

Parasitology Research, 2013
Rhipicephalus microplus is the main tick that affects cattle. Plant bioactive molecules can be used to control this ectoparasite. The aim of this study was to evaluate the in vitro efficacy of Piper tuberculatum fruit extracts obtained with different solvents on R. microplus larvae and engorged females.

Piplartine, an amide alkaloid from Piper tuberculatum, presents anxiolytic and antidepressant effects in mice

Phytomedicine, 2007
In the present work, we studied the effects of piplartine (PIP), an amide alkaloid isolated from the roots of Piper tuberculatum (Piperaceae), in the elevated plus maze, open field, rota rod, pentylenetetrazole (PTZ)-induced seizures, and forced swimming tests, in mice (Swiss, male, 25 g) to assess anxiolytic, sedative, muscle relaxant, anticonvulsant ...

An endophytic Pseudomonas sp. of Piper tuberculatum promotes growth on Piper nigrum through increase of root biomass production

Physiological and Molecular Plant Pathology, 2019
Abstract Microorganisms that can positively influence plants have emerged as a powerful tool for sustainable agriculture. Previous studies identified a Pseudomonas sp. (Pt13) associated with the roots of Piper tuberculatum, a member of the Piperaceae occurring in the Amazon region with known resistance to infection by Fusarium solani f. sp.

Piplaroxide, an Ant-Repellent Piperidine Epoxide from Piper tuberculatum

Journal of Natural Products, 1996
Investigation of leaves from the shrub Piper tuberculatum for compounds that might serve as repellents to leafcutting ants has led to identification of three cinnamic acid derivatives. One has been characterized as a new piperidine epoxide, piplaroxide (1), while the other two were recognized as the known compounds piplartine (2) and ...
