Abstract

The use of medicinal plants is a very old practice, used by most of the people around the world. Lupinus albus (L. albus), popularly known as white lupine, has been used in popular medicine in form of raw seeds, as a regulator of blood glucose and cholesterol. Although literature describes that their isolated proteins have the this potential, there is no scientific information regarding the efficiency of their raw seeds. The aim of this study was to evaluate the possible genotoxic, antigenotoxic, mutagenic, antimutagenic, anticarcinogenic and carcinogenic effects, and also the immune modulatory potential of aqueous extract of raw seeds of L. albus, by means of bone marrow micronucleus, aberrant crypt foci in colon, leukocyte counting, blood glucose and serum cholesterol levels of mice Mus musculus, as well as to determine and quantify alkaloids and fatty acids of these extracts, by gas chromatography. The effects of concentrations equivalent to 3 seeds/day (as used in popular medicine) and 9 seeds/day were evaluated in mice. Chemical analysis of the extract showed the presence of the alkaloid lupanine and oleic, linoleic, palmitic and stearic fatty acids. However, according to biochemical assays, it was not possible to observe hypoglycemic effects of L. albus in both followed protocols. It was observed that cholesterol levels showed an improvement in the protocol using DMH. No cytotoxic effects were observed in the MN assay in bone marrow, but genotoxic and mutagenic effects were recorded in highest concentration of the tested extract. Antigenotoxic and antimutagenic effects were also observed, demonstrating a preventive action for the two concentrations tested due to the promotion of harm reduction for pre-extract treatment. When the extract of L. albus was administered simultaneously with DMH, a reduction in damage was... (Complete abstract click electronic access below)
