Diversos estudios sobre la acción inhibitoria de crecimiento del extracto acuoso exento de alcaloides de Erythroxilum novogranatense (Morrys) varo truxillense (Rusby), frente a diversas cepas de bacterias, hongos, bacterias cariogénicas y cepas ATCC, hemos reportado anteriormente.Estudios anteriores sobre Plantago major L -Llantén", reportan componentes quimicos como: glicósidos, aucubinas, flavonoides, terpenos, taninos, resinas, ácidos orgánicos, minerales, vitaminas y otros elementos.Se realizó las determinaciones fitoquimicas en muestras de ambas especies, los extractos acuosos fueron esterilizados separadamente mediante filtros de Millipore, para realizar las determinaciones de acción inhibitoria de crecimiento frente a bacterias y hongos.La proporción de la asociación de los dos extractos acuosos empleados fue de 50/50, como óptimo para nuestro estudio.Se emplearon 63 ce...

In the present investigation a phitochemical study of Prezia multiflora(H et B) lees Escorsonera was accomplished in order to determine the presence of secondary metabolites. A botanic study of this specie has been made to indicate its systematic location and morfhological description.A chemical and pharmacological review of the mayor components, as flavonoids and alcaloids; has also been performed. TLC and preparative chromatography were done, ending with the separation of two flavonoids. The identification of the flavonoid (flavonone type) as 7-O-RHAMNOGLUCOSIDE-3',5- DIHYDROXY -4'METOXYFLAVANONE, was done by UV spectroscopy. The other one probably would be: 3',5,7-TRIDIHYDROXY -4' -METOXYFLAVANONE. Two alcaloids were also identified and their probable structure would be: 1,4-(1,3-PIPERIDIL-DIENO)-2,5-0XO-6-HYDROXY-2H,3H-INDOL-ETENO and 1,4-(1,3-PIPERIDIL-DIENO)-2,5-0XO-6-0-GLUCOSYL-2H...

The presence of secondary metabolites and of chromium element in seven medicinal plants empirically used for their hypoglycemic action by a phytochemical screening and a qualitative method and other one that is quantitative by Atomic Absorptioli. Spectroscopy for detelmining trivalent chromium has been researched. The studied species are: Phyllantus niruri L. (Chancapiedra), Geranium dielsianum Knut (Pasuchaca), GentianeIla alborosea G. (Hercampure), Otholobium pubescells (Culén), Smallantus sonchifolia (Yacón), Chloraphora tincoria (Mora) y Taraxacum officinalis W (Diente de león). It was phytochemically determined the presence of the following secondary metabolites: alkaloids, flavonoids , tannins, saponins and glycosides, by means of color and precipitation reagents. The determination of chromium element was carried out by qualitative and quantitative via. The accomplished study co...
