Avaliação mutagênica de infusões de folhas de Myrciaria floribunda (H.West ex Willd.) O. Berg. E Eugenia uniflora L. por meio do teste de Allium cepa L

Abstract

The empirical and indiscriminate use of medicinal plants to treat diseases can have serious consequences for human health. Despite the new methods available by the drug industries, a large part of the population still uses medicinal plants due to the traditions and habits of generations and communities, which makes it necessary to know and study the characteristics and preparation of these plants. The leaves of the species Myrciaria floribunda (H.West ex Willd.) O.Berg and Eugenia uniflora L, popularly known as cambuizeiro and pitangueira, of the Mirtaceae family, stand out for their medicinal properties. The present work aimed to analyze the mutagenic potential of M. floribunda and E. uniflora L. by the Allium cepa L. test. Four treatments with four replications were performed by infusion of fresh leaves of cambuizeiro and pitangueira: (C-) distilled water (negative control); (C +) acetaminophen 800mg L-1 (positive control); (C1) 150mg L-1 and (C2) 300mg L-1 . The results obtained by Software SAEG 9.1 showed significant difference by Scott-Knott test (p≤0.05). For M. floribunda and E. uniflora in the tested concentrations, there was a difference in relation to the positive control, which presented the highest average of 13.6 and 13.5, respectively. Thus, allowing the consumption due to low mutagenicity.
