AIM OF THE STUDY The aim of this study is to explore the anti-inflammatory properties of Cymbopogon citratus leaves and their(More)
Dendritic cells (DC) are professional antigen-presenting cells with a unique capacity to initiate and modulate immune responses by their ability to prime naïve T-cells. Upon stimuli, DC experience several morphologic, phenotypic and functional changes in a process referred to as maturation. This process is crucial to the biological functions of DC since(More)

Agrimonia eupatoria L. (agrimony) is a medicinal plant largely used in traditional medicine. Recently, phytochemical studies on an agrimony hydro-alcoholic extract and a polyphenol-enriched fraction obtained from it were carried out. The fraction was found to possess a high concentration of flavan-3-ols, flavonols, flavones and phenolic acids. So, the main(More)
Liquid chromatography coupled to diode array and electrospray ionization mass spectrometry detection was used to establish the polyphenolic profile of an ethyl acetate fraction from Agrimonia eupatoria L. aqueous-alcoholic extract. Additionally, an HPLC technique with post-column derivatization by p-dimethylaminocinnamaldehyde was employed for the selective(More)
Passiflora edulis Sims together with several other plants of the genus Passiflora have been reported to possess anxiolytic properties. It has been suggested recently that flavonoids may be partly responsible for the neuropharmacological activity of these plants but there are still few data reporting the relation between the constituents of these plants and(More)
Decoctions prepared from the bark of Uncaria tomentosa (cat's claw) are widely used in the traditional Peruvian medicine for the treatment of several diseases, in particular as a potent anti-inflammatory agent. Therefore, the main purpose of this study was to determine if the well-known anti-inflammatory activity of cat's claw decoction was related with its(More)
