Resumo

Portulaca oleracea L., vulgarmente conhecida como beldroega, é uma planta consumida na Europa, Ásia e África, com compostos nutracêuticos e ácidos gordos essenciais cujo conteúdo excede o de vegetais como espinafre e alface. Por outro lado, a adubação orgânica melhora as características físico-químicas do solo e assim promove o crescimento, a fisiologia e o metabolismo secundário, melhorando a composição química da planta. Para avaliar o efeito da adubação orgânica no teor de ácidos graxos e na atividade antidiabética (α-Glucosidase), plantas cultivadas em casa de vegetação foram submetidas a três tratamentos: controle sem adubação adicional, com composto e vermicomposto. Os resultados indicaram que o vermicomposto aumentou significativamente o teor de ácido oleico e linoléico. Entretanto, o teor de ácido palmítico diminuiu, embora outros ácidos graxos saturados, como os ácidos láurico, mirístico e esteárico, não tenham apresentado variações nos diferentes tratamentos. Dos ácidos graxos essenciais poliinsaturados, o ácido linolênico (ômega-3) aumentou no tratamento de controle. Por outro lado, a enzima α-Glucosidase não apresentou diferenças nos diferentes tratamentos de fertilização. Contudo, a sua elevada percentagem de inibição (60 %) posiciona-a como uma espécie com elevado potencial antidiabético.
