Abstract:

In the present work, the pharmacognostic and preliminary phytochemical analysis of the species Mansoa hymenaea (DC.) A.H. Gentry that is located in the Peripa commune in Santo Domingo de los Tsáchilas. The phytochemical and pharmacognostic composition of the stem and leaves was analyzed by phytochemical screening techniques identifying their chemical groups. The extraction of its essential oils was also carried out analyzing them by means of instrumental methods such as GC-MS. The results in the phytochemical screening indicated that they have abundant groups such as alkaloids, lactones and coumarins and the presence of mucilages, saponins, reducing sugars, etc. Regarding the physicochemical parameters, they showed that the values of the leaves are high in comparison with those of the stem, according to the ranges established by the WHO. Finally, the GC-MS analysis identified different sulfur compounds.
