Resumo: |
The low cytotoxicity and anti-inflammatory action are interesting features for mouthwashes, toothpastes and dental medication. Therefore, it is necessary to evaluate these properties in plant glycolic extracts which can be ingredients of the formulation of these products. This study evaluated the following biological activities for each of the glycolic extracts of Cynara cardunculus var. scolymus (L.) Fiori (artichoke), Myracrodruon urundeuva Allemão (pepper tree) and Camellia sinensis (L.) Kuntze (green tea) in mouse macrophage cultures (RAW 264.7) by the exposure time of 5 min and 24 h. a) cytotoxicity by MTT method in 11 serial dilutions, the initial concentration of the extracts was 200 mg/mL. b) Anti-inflammatory activity after stimulation with lipopolysaccharide (LPS) of Escherichia coli was performed by immunoenzymatic test (ELISA) using specific antibodies to quantify IL-1 , TNF- and IL-10. The results were subordinated to statistical analyses (ANOVA and Turkey test), with p 0,05. The cytotoxicity of the extracts was dependent on dose and time. At 5 min exposure time, artichoke extract showed cytotoxicity at a concentration of 200 mg/mL. At 24 h exposure time, green tea showed cytotoxicity at the concentrations 50 mg/mL, pepper tree stimulated the proliferation of macrophages in the concentrations of 0,39mg/mL to 12.5 mg/mL and artichoke showed cytotoxicity at the concentrations 12.5 mg/mL. Green tea extract showed anti- inflammatory potential at a concentration of 12.5 mg/mL and was dependent on dose, promoting a decrease production of pro-inflammatory cytokines as IL-1 and TNF- . Pepper tree presented immunopotentiating action at a concentration of 12.5 mg/mL at 24 h of exposure time. Regarding artichoke, there is a need for further studies to identify their immunomodulatory action. |
