Análisis fitoquímico y evaluación de las actividades antimicrobiana e hipolipemiante de Bidens odorata Cav. y Dodonaea viscosa Jacq

Se calcula que aproximadamente en el mundo existen 250,000 plantas superiores agrupadas en 41 familias, de las cuales, solo del 5-­‐15% han sido sometidas a estudio fitoquímico para obtener un potencial valor terapéutico. De éste pequeño porcentaje, la información etnobotánica indica que aproximadamente 800 plantas son usadas como remedio tradicional en el tratamiento de patologías como diabetes, hipertrigliceridemia, hipercolesterolemia, etc. Dentro de estas familias, se encuentran la familia Compositae (Asteraceae) y la Sapindaceae. La realización de este trabajo de investigación tiene como propósito efectuar el estudio fitoquímico, antimicrobiano e hipolipemiante de extractos vegetales de diferente polaridad de las especies Bidens odorata Cav. y Dodonaea viscosa Jacq. procedentes de los estados de Tlaxcala y Durango. La selección de Bidens odorata se hizo con base en sus propiedades antipiréticas, por su actividad hipoglucemiante, su efecto gastroprotector, antidiarreíco, diurético. Por su parte, Dodonaea viscosa fue elegida debido a su efecto hipolipemiante y antioxidante, hepatoprotector, antiinflamatorio, antitumoral, antidiabética, entre otros, todas estas descritas en la medicina tradicional

Comparative Study of Heavy Metals in Selected Medicinal Plants and Extracts, Using Energy Dispersive X-ray Fluorescence

The use of plants has grown constantly worldwide, being a rich source of compounds that serve as established treatments for various diseases and conditions. This paper discusses the elemental composition and the level of environmental risk of heavy metals of selected medicinal plants. The extracts are investigated by energy dispersive X-ray fluorescence, a non-destructive, fast, multi-element, highly accurate and environmentally friendly analysis compared to other elementary detection methods. The studied plants Croton dioicus and Phoradendron villosum are native to Mexico. Both showed high levels of Cu and Ni, while their extracts present levels within the permissible range

Antifungal Activity of Mexican Propolis on Clinical Isolates of <i>Candida</i> Species

Infections caused by micro-organisms of the genus Candida are becoming a growing health problem worldwide. These fungi are opportunistic commensals that can produce infections—clinically known as candidiasis—in immunocompromised individuals. The indiscriminate use of different anti-fungal treatments has triggered the resistance of Candida species to currently used therapies. In this sense, propolis has been shown to have potent antimicrobial properties and thus can be used as an approach for the inhibition of Candida species. Therefore, this work aims to evaluate the anti-Candida effects of a propolis extract obtained from the north of Mexico on clinical isolates of Candida species. Candida species were specifically identified from oral lesions, and both the qualitative and quantitative anti-Candida effects of the Mexican propolis were evaluated, as well as its inhibitory effect on C. albicans isolate’s germ tube growth and chemical composition. Three Candida species were identified, and our results indicated that the inhibition halos of the propolis ranged from 7.6 to 21.43 mm, while that of the MFC and FC50 ranged from 0.312 to 1.25 and 0.014 to 0.244 mg/mL, respectively. Moreover, the propolis was found to inhibit germ tube formation (IC50 ranging from 0.030 to 1.291 mg/mL). Chemical composition analysis indicated the presence of flavonoids, including pinocembrin, baicalein, pinobanksin chalcone, rhamnetin, and biochanin A, in the Mexican propolis extract. In summary, our work shows that Mexican propolis presents significant anti-Candida effects related to its chemical composition, and also inhibits germ tube growth. Other Candida species virulence factors should be investigated in future research in order to determine the mechanisms associated with antifungal effects against them
