Abstract

Malária é uma doença que preocupa as entidades de saúde nos países tropicais pelo número crescente de casos e pela resistência parasitária do protozoário infectante e do mosquito transmissor a inseticidas. Senna occidentalis e S. reticulada são utilizadas no tratamento e profilaxia da malária e o objetivo desse trabalho foi identificar substâncias quimicamente ativas em células e/ou tecidos dessas espécies. Análises anatômicas, histoquímicas e fitoquímicas foram feitas segundo metodologias usuais. As folhas de S. occidentalis e S. reticulata são semelhantes em relação à estrutura anatômica, diferenciando-se na presença de tricomas glandulares em S. occidentalis, papilas na epiderme de S. reticulata, e na composição histoquímica. As raízes das duas espécies analisadas também se assemelham, destacando-se a presença de fibras gelatinosas, cristais prismásticos e drusas. A prospecção fitoquímica revelou cumarinas, flavanonas, catequinas, esteroides livres, saponinas e bases quaternárias.
