Cashew apple juice and cajuina (processed juice) are drinks widely consumed in northeast Brazil. In vitro studies have shown that both juices have antimutagenic activity as well as antioxidant effects. These juices contain vitamins, carotenoids, and phenolic compounds. This in vivo study assessed the antigenotoxic and anticlastogenic effects of both drinks against genotoxicity and mutagenicity induced by cyclophosphamide. The comet, micronucleus, and chromosome aberrations tests were used. Male Swiss mice were divided into 6 groups (5 animals per group) and received the following by gavage, 0.15 mL/10 g body weight: group 1, water; group 2, cashew apple juice; group 3, cajuina juice; group 4, cashew apple juice and cyclophosphamide (50 mg/kg); group 5, cajuina juice and cyclophosphamide; group 6: cyclophosphamide. Both drinks significantly reduced DNA damage of peripheral blood cells (P<.001), with modulation percentages of 60.82% (cashew apple juice) and 82.19% (cajuina) when compared with the cyclophosphamide group. Cashew apple juice and cajuina modulated cyclophosphamide-induced micronucleus frequency, with up to 80.0% inhibition. Cashew apple juice and cajuina decreased the average number of cells with chromosome aberrations in bone marrow of mice by 53% and 65%, respectively. These findings demonstrate the high antigenotoxic and anticlastogenic potential of cashew apple juice and cajuina in vivo, which can be related to the antioxidant compounds found in both drinks.

The use of herbal products and/or their derivatives as an alternative or complementary medicine becomes globally popular. To date, various biological activities have been reported in Morinda citrifolia Linn, especially antioxidants, antimicrobial, anti-infammatory and antitumor efects. This study aimed to investigate the genotoxicity and DNA repair capacity of the aqueous fruit extract of M. citrifolia (AEMC). Additionally, we checked the mutagenic capacity of AEMC by the comet assay and micronucleus tests in rats. For this, rats (n=10; 5 males and 5 females) were divided into fve groups as: negative control (distilled water); positive control (25 mg/kg of cyclophosphamide, i.p.); and three groups for AEMC (2.5, 5 and 10 mg/kg, i.p.). The results suggest that, the AEMC induced genotoxicity in white blood cells, but a DNA repair capacity was also observed after 72 h of AEMC exposure. AEMC also showed cytotoxicity and mutagenicity in liver and kidney cells of rats at 5 and 10 mg/kg doses. In conclusion, AEMC exhibited a dose-dependent cytotoxicity, genotoxicity and mutagenicity along with a time-dependent DNA repair capacity in rats. Further studies are necessary regarding the safe use of this medicinal plant for human consumption.
