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...

It was carried out the comparative evaluation of three synthetic drugs used as oral hypoglycemiants, against the aqueous obtained by infusion of leaves from Smallantus sonchifolius (Poepp) Rob. Yacon , using a experimental biomodel by hypoglycemia in normoglycemic rats of species Rattus norvegicus Var. Albine. The object of the research was to observe the 10 % aqueous extract effect of Smallantus sonchifolius (Poepp) Rob. Yacon in the decay of glycemia against glibenclamide, c1orprofamide and metformine drugs that have great usage in the treatment of type 2 diabetes mellitus (DM2). The vegetal material was collected in the Huancabamba district, province of Oxapampa in Cerro de Pasco department. The pharmaeological assay was taken with 36 female albine rats of Holtzman strain , with a average weight of 240g that were fed by a controlled foad and water ad libitum until the moment of experi...

Se realizó 1a evaluación comparativa de tres fármacos de síntesis utilizados como hipoglicemiantes orales con el extracto acuoso obtenido por infusión de las hojas de Smallanthus sochifolíuS (Poepp) Rob. "yacón", utilizando un biomodelo experimental por hiperglicemia en ratas normoglucémicas de la especie Rattus norvegicus var. Albina. El objetivo de la investigación fue observar el efecto del extracto acuoso al 10% de las hojas de "yacón" en el descenso de la glicemia frente a la glibenclamida, clorpropamida y metformina, que tienen amplio uso en el tratamiento de la diabetes mellitus tipo 2 (DM2). El material vegetal fue colectado en el distrito de Huancabamba provincia de Oxapampa del departamento de Cerro de Pasco. El ensayo farmacológico se realizó con 36 ratas albinas hembras, cepa Holtzman con un peso promedio de 240 g, que estuvieron sometidas a una alimentación cont...

A study of the essential oil extracted from the leaves and flowers of the Thymus vulgris L. ''Tomillo'' by stearn distillation method was carried out. Samples were determined by physico-chemical analyses and chemical composition was obtained by GC/MS mass spectrophotometer coupled to gaschromatographer, determining the following hydrocarbonated compounds like: Thujene; 1,3,6 Octatriene,3,7-Dimethyl; Camphene; Beta Myrcene; Delta 4 Carena; Beta Selinene; Delta Cadinene; Benzene 1 methyl, 4 (l-methyl ethyl); Gama Terpinene; Trans Caryophyllene; Germacrene D.; Trans Caryophyllene; Beta Bisabolene y compuesto oxigenados como: 7 octen, 401 (CAS); l.6 octadien, 3 0l, 3,7 Dimethyl Acetate; Linalool; Isoborneol; carvacrol; Thymol; Farnesyl acetate 2.At the same time, antimicrobial activity was determined against pathogenic strains from clinical samples and from ATCC (American Typical Cultivate C...

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).
