Foram realizados estudos sobre o conhecimento indÃgena no tratamento da febre tifoide e infecções de feridas utilizando o extrato de folhas da planta Calotropis procera. As folhas foram arrancadas e secas ao ar até obterem um peso constante, pulverizadas com quatro solventes diferentes: aquoso, n.hexano, etanol e metanol. Duzentos e cinquenta gramas da amostra seca e pulverizada foram pesados para cada extração por solvente e foram obtidos 28,50 1,00 (g), 12,30 1,00 (g), 16,40 1,0 (g) e 22,60 1,00 (g) com peso correspondente de isolados puros fraccionados do extrato obtido por cromatografia em coluna de 13,00 1,00, 7,20 1,00, 8,80 1,00 e 10,30 1,00 (ml). Os resultados da análise fitoquÃmica revelaram os componentes activos mais elevados de taninos, saponinas, alcalóides, flavonóides, glicosÃdeos cardÃacos e terpenóides nos extractos metanólicos, ao passo que o açúcar redutor, o fenol e os flobataninos estavam ausentes. Utilizando métodos de difusão em ágar, os diferentes extractos brutos mostraram um efeito visÃvel nos organismos de teste em comparação com os isolados puros fraccionados dos extractos e o controlo positivo. Observou-se que os extractos metanólicos eram mais potentes do que outros extractos de solventes nas bactérias testadas.
