FTIR identified the carbonyl C = O functional group of the anthraquinone derivatives in aqueous macerated and alcoholics purges as aloe plants (Aloe vera L. , Aloe barbadensis Miller ) , senna ( Cassia spp . ) , Rhubarb ( Rheum palmatum) and shell sagrada (Rhamnus Pursiana ) without prior separation of the components by chromatographic methods or other physical and chemical methods . We show that the absorption maxima for the C = O carbonyl group of the anthraquinone derivatives in aqueous and alcoholic macerated Aloe vera and Aloe barbadensis L. Miller- interact with inorganic salts - for a week , as time passes, these maxima moving to higher-frequency areas . This procedure can be recommended for detection of anthraquinone derivatives in encapsulated pharmaceutical preparations and extracts of the plants mentioned purgatives

Por FTIR se identifica al grupo funcional carbonilo C=O de los derivados antraquinónicos en macerados acuosos y alcohólicos de plantas purgantes como aloes (Aloe vera L., Aloe barbadensis Miller), sen (Cassia sp.), ruibarbo (Rheum palmatum) y cáscara sagrada (Rhamnus pursiana), sin separación previa de los componentes por métodos cromatográficos u otros métodos físico químicos. Se demuestra que los máximos de absorción para el grupo carbonilo C=O de los derivados antraquinónicos en macerados acuosos y alcohólicos de Aloe vera L. y Aloe barbadensis Miller -interactúan con sales inorgánicas durante una semana-, conforme transcurre el tiempo, estos máximos se desplazan a zonas de mayor frecuencia. Este procedimiento puede recomendarse para la detección de los derivados antraquinónicos en extractos y preparados galénicos encapsulados de las plantas purgantes mencionadas

Seeds of chirimoya and guanabana from the communities of Cumbe and Callahuanca - Yauyos, Lima were analyzed. The extraction of natural toxic was realized using ethanol as the optimal solvent, after several solvent tests, phytochemicals analysis identified :saponins, coumarins, tannins, quinones and essential oils, mostly castor oil which was confirmed by FTIR spectra. Qualitative analysis results identified: PO4(3-), AsO4(3-) and others. Toxicological tests extracts applied on larvae and fruit flies finding levels of mortality as 88% to 94% on chirimoyas and guanabanas respectively.

Aqueous extractions were performed controlling the pH with CaCO3 and Ca(OH)2, using as clarifiers activated coal and activated clays in cold and warm solutions to obtain best results with cold bentonite, warm activated clay and warm activated coal. Analytical results were compared with a commercial sample of stevia.
