Morfoanatomia comparativa das folhas de Piper arboreum Aubl. e Piper tuberculatum Jacq.

Antimicrobial activity of Piper arboreum and Piper tuberculatum (Piperaceae) against opportunistic yeasts

Proteomic profile of Piper tuberculatum (Piperaceae).

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. Over a hundred spots and various peptides were identified in this...

Antiparasitic Activity and Essential Oil Chemical Analysis of the Piper Tuberculatum Jacq Fruit

With the increase of neglected diseases such as leishmaniasis and Chagas disease, there wasa need for the search for new therapeutic alternatives that reduce the harm caused by medicineavailable for treatment. Thus, this study was performed to investigate the antiparasitic activityof the essential oil from the fruits of Piper tuberculatum Jacq, against lines of Leishmaniabraziliensis (MHOM/CO/8...

Hydrolysis of Methyl Benzoate from Piper arboreum by Naupactus bipes Beetle

O 3-geranil-4-hidroxibenzoato de metila (1), um novo produto natural, foi isolado das folhas de Piper arboreum (Piperaceae). O metabolismo das folhas de P. arboreum pelo besouro Naupactus bipes (Germar, 1824 Coleoptera: Curculionidae) resultou na biotransformação de 1 para o ácido 3-geranil-4-hidroxibenzoico (2). As estruturas dos metabólitos 1 e 2 foram determinadas com base na interpretação d...
