Trypanocidal activity of Piper arboreum and Piper tuberculatum (Piperaceae) [PDF]

Revista Brasileira de Farmacognosia, 2009
In the scope of our ongoing research on bioactive agents from Brazilian flora, twenty-four extracts and fractions obtained from Piper arboreum Aub. and Piper tuberculatum Jacq. (Piperaceae) were screened for trypanocidal activity by using MTT colorimetric assay. The strongest activity was found in hexane fractions from the leaves of P.

Rationalising the retro‐Diels‐Alder fragmentation pattern of viscutins using electrospray interface‐tandem mass spectrometry coupled to theoretical modelling

Rapid Communications in Mass Spectrometry, Volume 37, Issue 15, 15 August 2023., 2023
Rationale Although mass spectrometry (MS) is a powerful tool in structural elucidation of unknown flavonoids based on their unique fragmentation patterns, proposing the correct fragmentation mechanism is still a challenge from tandem mass spectrometry data only.

Fruit secondary metabolites alter the quantity and quality of a seed dispersal mutualism

Ecology, Volume 104, Issue 5, May 2023., 2023
Abstract Plant secondary metabolites are key mechanistic drivers of species interactions. These metabolites have primarily been studied for their role in defense, but they can also have important consequences for mutualisms, including seed dispersal.

Antischistosomal Activity of Origanum majorana, Ziziphus spina-christi, and Salvia fruticosa Plant Extracts on Hamster Infected with Schistosoma haematobium

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
World Health Organization (WHO) has approved only one treatment for schistosomiasis, praziquantel (PZQ), but some poor efficacy was noticed in patients during the early stage of infection. Therefore, researchers have intensified their efforts to research new alternative medicines to treat schistosomiasis.
