Este estudio reveló hallazgos muy importantes sobre el perfil de toxicidad agudo y subagudo del extracto etanólico de Tanacetum parthenium, que son de utilidad para el estudio clínico de esta planta. La toxicidad del extracto fue evaluada observando sus efectos en ratas y ratones. Se evaluó los cambios hematológicos, de parámetros bioquímicos y también observando los cambios histopatológicos del hígado. Los resultados del estudio de toxicidad subaguda indican que la administración oral de Tanacetum parthenium en dosis altas tiene efectos tóxicos en los tejidos del hígado. En conclusión, se confirma que el uso de Tanacetum parthenium es seguro para el consumo humano en dosis menores a 500 mg. por Kg.

El presente estudio realizado en zonas urbano marginales de la ciudad de Ayacucho tuvo como objetivo detectar prácticas inadecuadas de uso de medicamentos, corregirla mediante intervención educativa y determinar la eficacia de esta. La metodología utilizada fue la encuesta domiciliaria, para investigar las características de uso de medicamentos, en el tratamiento de las afecciones más comunes. El muestreo empleado fue aleatorio simple para escoger los domicilios a encuestar, que se dividieron en grupo intervenido y grupo control, donde los participantes fueron personas voluntarias. En una primera encuesta se encontró que las afecciones más frecuentes fueron el resfriado común y las enfermedades diarreicas agudas y que a menudo su manejo consistía en el uso inadecuado de medicamentos. Se llevaron a cabo intervenciones educativas de dos semanas por asentamiento humano, y posterior...

The anti-inflammatory and antioxidant activity of the hydroalcoholic extract of the fruit of the orange, purple and white varieties of Opuntia ficus-indica was determined. The methods were: total phenols by Folin-Ciocalteu, flavonoids by aluminum chloride and antioxidant activity by DPPH, ABTS and FRAP; the anti-inflammatory activity in vitro by the red blood cell membrane stabilization method. The total phenolic content for the orange, white and purple varieties were 4.08, 3.87 and 3.69 mg GAE/g (p> 0.05). The flavonoid content was higher in the orange variety with 2.36 mg QE/g, followed by the purple and white varietywith 2.29 and 2.0 mg QE/g (p <0.05). In the free radical scavenger for DPPH the orange variety presents a higher activity of 6.20 μmol TE/g (p <0.05), for ABTS the purple variety presents 25.35 μmol ET/g (p<0.05) and for the ferric reducing activity potential...

Objective: To evaluate the gastroprotective effect of mucilage extracted from Aloe vera (A. vera) leaves in albino rats. Materials and methods: The technique used was observation, and the method was based on inducing gastric ulcers with 96 % ethanol. The animals were divided into seven treatment groups: (I) control group, which received normal saline (4 mL/kg); (II)group administered 96 % ethanol (1 mL/animal); (III) group treated with ranitidine (100 mg/kg); (IV) group administered sucralfate (50 mg/kg); and (V–VII) groups treated with mucilage at doses of 25, 50, and 100 mg/kg, respectively. Results: The mean volumes of gastric content in animals treated with mucilage at doses of 50 and 100 mg/kg were statistically comparable to those in the ranitidine and sucralfate groups. The percentage efficiency in increasing gastric pH of the experimental animals was highest with ranitidine, fo...

Aims: Cancer is the first cause of death in the Peruvian population; searching alternative treatments of medicinal plants constitute a promissory field to find new anticancer drugs. The main objective in this study was to evaluate the phytochemical screening, total phenolic content, antioxidant and cytotoxic activity of ethanol extract of Chromolaena laevigata (C. laevigata) on human tumor cell lines. Study Design: The fresh leaves of C. laevigata were soaked with ethanol followed by phytochemical screening using standard methods. Place and Duration of Study: Laboratory of Applied Chemistry, Faculty of Pharmacy and Biochemistry, Universidad Nacional San Luis Gonzaga de Ica, Ica, Peru; Laboratory “Abraham Vaisberg Wolach”, Universidad Peruana Cayetano Heredia, Lima, Peru. Methodology: Phytochemical screening was assessed by using chemical reactives. Total phenolic content (TPC) was de...

Neem has become valuable plant in the world which shows the solutions for hundreds to thousands problems. Azadirachta indica (Neem) is a rapidly growing evergreen well known tree found Pada generally in various regions of world like America, Africa and India. It has been widely used in Chinese, Ayurveda and Unani medicines across the world especially in Asians countries for the prevention and treatment of diseases. The different parts of neem plant contain biological compounds responsible for antibacterial, antiviral and antifungal activities. It is considered as safe medicinal plants and modulates the numerous biological processes without any adverse effect. Neem tree produces some active compounds which contain biological activities, parts of neem tree such as Root, bark, leaf, flower, seed and fruit together possesses biological activities. Various compounds have been obtained from va...

Schinus molle is a medicinal plant used as an anti-inflammatory and for rheumatic pain in the traditional medicine of Peru. On the other hand, Aedes aegypti is the main vector of several tropical diseases and the transmitter of yellow fever, chikungunya, malaria, dengue, and Zika virus. In this study, the aim was to investigate the antioxidant activity in vitro and the insecticidal activity in silico, in the presence of the mosquito juvenile hormone-binding protein (mJHBP) from Aedes aegypti, of the essential oil from S. molle leaves. The volatile phytochemicals were analyzed by gas chromatography-mass spectrometry (GC-MS), and the profile antioxidants were examined by DPPH, ABTS, and FRAP assays. The evaluation in silico was carried out on mJHBP (PDB: 5V13) with an insecticidal approach. The results revealed that EO presented as the main volatile components to alpha-phellandrene (32.68%...
