“…We show that this phytoconstituent has antifungal effect. Another study by Kaloustion et al (2008) demonstrated that carvacrol had an MIC of 400 lg/mL for E. coli ATCC 10536, and S. aureus ATCC 65288 by broth dilution method.…”

Background: Cryptococcus neoformans is the etiologic agent of opportunistic systemic fungal infection cryptococcosis, which affects individuals with compromised immune systems. Thus, natural products research has become important, since monoterpenes such as carvacrol, a promising molecule in the search antifungal agents, have shown significant biological activity. Objective: The study aimed to investigate the antifungal activity and mode of action of carvacrol against strains of C. neoformans. Methods: The minimum inhibitory concentration (MIC) was determined by microdilution method. Minimum fungicidal concentration (MFC) was performed by seeding technique on solid media. Studying the mode of action was performed using broth microdilution. Results: The MIC ranged from 25 to 81 lg/mL and the MFC ranged from 25 to 102 lg/mL. Carvacrol bonded to exogenous ergosterol and cholesterol. Discussion: The results suggest that carvacrol has antifungal activity against C. neoformans and its mode of action is related to fungal membrane instability. Conclusions: The phytoconstituent carvacrol may eventually become a drug; however, further studies are needed to elucidate its mechanism.

“…Imelouane et al [33] found for this same species EO MIC values equal to 1.33 mg/mL for the strains E. coli, S. aureus and S. epidermidis. Kaloustian et al [34] found MICs equal to 1 and 2 mg/mL for the strains E. coli and S. aureus respectively, while testing the EOs of T. vulgaris and T. zygis.…”

“…Par ailleurs, ces coumarines sont à même de réduire la multiplication des bactéries pathogènes et ainsi, empêcher la formation de gaz et de métabolites toxiques au niveau intestinal (Harkati, 2011). En effet, le caractère lipophile des coumarines leur permet comme tous autres phénols de se lier aux membranes cellulaires des microorganismes et d'inhiber les échanges d'électrons membranaires lors de la phosphorylation oxydative freinant le métabolisme cellulaire (Teuscher et al, 2005 ;Kaloustian et al, 2008). Les coumarines agissent comme les flavonoïdes, elles ont la capacité de prévenir la peroxydation des lipides membranaires et de capter les radicaux hydroxyles, superoxydes et peroxyles (Caesar, 2007 ;Mpondo et al, 2012).…”

RESUMEObjectif : Une enquête ethnobotanique a été conduite en février 2014 auprès des vendeuses des marchés Est de la ville de Douala concernant les différents usages des plantes à coumarines. Résultats : Au total, 38 espèces végétales à coumarines dont 25 herbacées et 13 ligneuses ont été inventoriées. Parmi ces espèces, 5 sont locales et 33 sont exotiques. Elles comprennent 34 genres repartis dans 21 familles dont la plus représentée est celle des Apiaceae. Le ravitaillement se fait dans les champs, les forêts secondarisées, les jardins de cases, vergers et jachères. Ces espèces sont pour la plupart cultivées et les feuilles, fruits et graines sont généralement utilisés pour la cuisine comme condiments ou comme épices. Parmi les maladies soignées par les plantes à coumarines recensées dans les marchés, les maladies de l'appareil digestif sont plus importantes (33,33 %). Les coumarines ont des propriétés antipyrétique, analgésique, sédative, antioedémateuse et anti convulsivante. Les plantes à coumarines et plus spécifiquement celles de la famille des Apiaceae ont la capacité de favoriser l'expulsion des gaz intestinaux entraînant une diminution des ballonnements et des flatulences. Elles augmentent la production stomacale d'acide contribuant à une bonne désinfection du bol alimentaire. Les coumarines ont la capacité de prévenir la peroxydation des lipides membranaires et de capter les radicaux hydroxyles, superoxydes et peroxyles. Conclusion et application des résultats : Toutes ces propriétés peuvent justifier l'intérêt accordé à ces plantes dans la médecine traditionnelle et leurs utilisations à des fins thérapeutiques, curatives et préventives. Mots clés : Ethnobotanique, coumarines, thérapeutiques, Apiaceae ABSTRACT Objective: An ethnobotanical survey was conducted in February 2014 with the vendors of the Eastern markets of the city of Douala on the different uses of coumarin plants.Results: A total of 38 plant species including 25 coumarin herbaceous and woody 13 were surveyed. Of these, 5 are local and 33 are exotic. They include 34 genera distributed in 21 families most represented is that of Apiaceae. Refueling is done in the fields, secondary forests, orchards and fallow. These species are mostly cultivated and leaves, fruits and seeds are generally used for cooking as a condiment or as spices. Among the diseases treated by coumarin plants identified in the markets, diseases of the digestive system are higher (33.33% analgesic, sedative, and anti convulsant antioedmatous. Coumarins plants and specifically those of the family Apiaceae have the ability to promote the expulsion of intestinal gas resulting in a decrease bloating and flatulence. They increase the production of stomach acid contributing to a good disinfection of the bolus. Coumarins have the ability to prevent the peroxidation of membrane lipids and capture hydroxyl radicals, superoxides and peroxyls. Conclusion and application of the results: All these properties can justify the interest given to these plants in traditional medicine and th...
