SIERES PEDRAJA, Eneyda; NIETO ACOSTA, Olga Maria  e  SANCHEZ ESPINOSA, Nohary. Assessment of physicochemical properties of Quassia amara and Maytenus ilicifolia tinctures. Rev Cubana Farm [online]. 2009, vol.43, n.4, pp. 85-92. ISSN 1561-2988.

The Quassia amara and Maytenus ilicifolia plants are known by its therapeutical properties on digestive tract. In present paper both plants were researched together by means of mixing of tinctures obtained to potentiate its phytopharmacologic action. Present study summarizes the physical-chemical properties of tinctures obtained by percolation using a 60 %-hydroalcoholic solution and a extraction time of 48 hrs in two variants: 1) mixtures of tinctures obtained from each plant to 20 % at a 10-90 % ratio (QA-MI), which was called C-tincture, the mixture of vegetal material in both plants in the same prior ratios in equipment, to obtain D-tincture. Parameters assessed in both tinctures (pH, relative density, refraction rate, total solids) were statistically compared. It was proved that total solids have significant differences with higher values present in D-tincture, which was selected for stability study. D-extract was studied during three months at different temperatures: refrigeration, room-temperature and at 40 ºC. In refrigeration temperature there are not changes in parameters assessed and in the other temperatures there appear slight changes in pH and alcoholic content.
