Investigating the phenolic profiles of the pulp and peel of nine plantain cultivars and compared them to those of two dessert bananas of commercial interest, alongside a newly created hybrid, resistant to black sigatoka disease, revealed that plantain pulps and peels appeared as good sources of phenolics.

Anti-inflammatory effects of pomegranate (Punica granatum L.) husk ellagitannins in Caco-2 cells, an in vitro model of human intestine.
The punicalagin-rich PomH extract tested showed anti-inflammatory properties in the Caco-2 in vitro intestinal model, acting both on the pro-inflammatory gene transcription and protein levels, suggesting that pomegranate husk could be an interesting natural source contributing to prevent intestinal chronic inflammation.

Affinities of nutty and green-smelling pyrazines and thiazoles to odorant-binding proteins, in relation with their lipophilicity.
Lipophilicity appears as an interesting discriminating physicochemical parameter, predictive of the affinity for OBPs and of the related odour profile. Expand
Piceatannol, a potent bioactive stilbene, as major phenolic component in Rhodomyrtus tomentosa.
Findings highlight the potential of sim, an under-utilised plant species from South-East Asia, as a source of health-promoting fruits. Expand
Antitrypanosomal compounds from the essential oil and extracts of Keetia leucantha leaves with inhibitor activity on Trypanosoma brucei glyceraldehyde-3-phosphate dehydrogenase.

Several of its constituents and three triterpenic acids present in the dichloromethane leaves extract showed a higher antitrypanosomal activity on bloodstream forms of Tbb as compared to procyclic forms, namely geranyl acetone, phytol, α-ion one, β-ionone, ursolic acid, oleanolic acid and betulinic acid.

A more complete structural characterization of polar organosulfates that originate from isoprene secondary organic aerosol was achieved, and an important atmospheric finding is the presence of anorganosulfate that is related to methyl vinyl ketone, a major gas-phase oxidation product ofIsoprene.

The in vitro antitrypanosomal and antileishmanial activity of crude extracts of 10 plant species traditionally used in Benin to treat parasitic infections are evaluated to give some justification for antiparasitic activity of some investigated plants. Expand
Antitrypanosomal compounds from the leaf essential oil of Strychnos spinosa.
The essential oil was active on the parasites without a great selectivity, but (E)-Nerolidol, a minor component of the hydrodistillate, as well as linalool, were shown to have a more potent and selective effect on the trypanosomes. Expand
HPLC-high resolution mass spectrometry in clinical laboratory?
Current high resolution mass spectrometric systems which could be useful for clinical applications are presented and illustrated with several applications, including the Time-of-Flight (TOF) and Orbitrap instruments. Expand
