dc.description.abstractPlants are an important source for the discovery of new products of medicinal value and unique sources for food additives, flavors, and other compounds with industrial value Commelina erecta L. (Commelinaceae) is an herbaceous flowering plant, popularly known as “trapoeraba” and “erva-de-santa-luzia”. In folk medicine, C. erecta has been used as antiviral, for the treatment of haemorrhages, skin rashes and sores, and for the treatment of infections [1]. Moreover, it is also used as a wild edible plant in salads, preserves or decorating the dishes [1]. The present study aims at evaluating the bioactive potential, namely, antioxidant, cytotoxicity to tumor and non-tumor cell lines, and anti-inflammatory activities of the stem and flower of C. erecta. Antioxidant activity was evaluated in the hydroethanolic extracts by two in vitro assays measuring inhibition of lipid peroxidation using thiobarbituric acid reactive substances (TBARS) assay and antihaemolytic activity (OxHLIA). The cytotoxicity was tested using four human tumor cell lines: AGS (gastric adenocarcinoma), CaCo (colorectal adenocarcinoma), NCI-H460 (non-small cell lung cancer), MCF-7 (breast carcinoma), as well a non-tumor culture from African green monkey (Vero). Anti inflammatory activity was determined based on the nitric oxide (NO) production by a murine macrophage (RAW 264.7) cell line. Significant differences between the evaluated extracts were observed, the hydroethanolic extract showed the best activity in the TBARS assay for the stem sample, with EC50 value of 0.63±0.01 mg/mL. On the other hand, in the OxHLIA assay, flower hydroethanolic extract present an IC50 of 5.1±0.2 μg/mL, value required to protect half of the erythrocyte population from the hemolytic action caused the used oxidative agent at Δt = 60 min. Stem sample presented effective results in the inhibition of the tested tumor cell lines, namely, AGS, CaCo and MCF-7, while flower is more effective against NCI-H460. Both extracts exhibited toxicity against non-tumoral cell lines, denoting that these extracts have cytotoxicity. The in vitro anti inflammatory potential of extracts was evaluated by measuring NO inhibition and the most effective extract was the flower with an EC50 values of 41±1 μg/mL. These results indicate that stems and flowers of C. erecta might be a potential source of natural biomolecules for pharmaceutical and food applications.pt_PT
