“…In Mato Grosso do Sul, Salmazzo et al [ 14 ] conducted an antiproliferative test and showed that there was no cytotoxicity in the fruit. Its extracts were tested on normal cell lines, in addition to showing promising results against cancer cell lines [ 18 , 29 ].…”

“…Furthermore, considering the use of GF either as a food or raw material for medicinal purposes, it is fundamental to investigate its toxicity. The lethality test against A. salina L. is widely used to evaluate the toxicity levels of several substances, including extracts and phytochemicals isolated from natural products [ 17 , 18 ]. In addition to testing the microcrustacean A. salina , the phytotoxicity of plant extracts in bioassays can be identified using L. sativa (lettuce) via the chemical control method from the inhibitory interference of seed germination and seedling growth upon exposure to the test plant [ 19 ].…”

Gabiroba, a native fruit in Brazil’s Atlantic Forest region, has significant nutritional and therapeutic properties. However, due to its seasonality, consumption by the population is limited. Thus, the development of gabiroba byproducts would add significant value to the food and therapeutic industries. Therefore, it is essential to study and support the lack of toxicity of gabiroba fruit extracts. In the present study, physicochemical analyses of fresh fruits (GF) and dehydrated whole gabiroba flour (WGF) and preliminary toxicity analyses of WGF were performed. The toxicity results showed a microcrustacean LC50 of >1000 mg/mL when exposed to WGF extracts at various concentrations (10–1000 μg/mL; p = 0.062) using the Artemia salina method, with no evidence observed of proliferative activity or toxic metabolic compounds in the WGF extract. The phytotoxicity of WGF using Lactuca sativa L. allowed germination and root growth at various concentrations of WGF extract, with the lowest (100 μg/mL) and highest (1000 μg/mL) concentrations exhibiting 98.3% and 100% seed germination, respectively. In conclusion, these results indicate that the WGF preparation preserved the nutritional and antioxidant potential of gabiroba fruits and that WGF is safe for use as a raw material in the food industry and for therapeutic purposes.
