Coleus blumei Benth (Lamiaceae), popularly known in Brazil as heart-hurt or coleus-of-Java is an ornamental plant widely used due to the color of its leaves. Several species of the genus Coleus present compounds with antioxidant, antimicrobial and allopathic activities due to the presence of chemicals such coleonol, forskolin and rosmarinic acid. Therefore, this study aimed to carry out phytochemical study and biological tests to evaluate the antibacterial, antioxidant and allopathic activities of the 70% ethanol extract and its fractions ethyl acetate, dichloromethane and end aqueous fraction leaf of Coleus blumei Benth. The plant extract was prepared by turbolisis from the powder of dried leaves, as a solvent for extraction using 70% ethanol. The ethanol extract was fractionated with solvents dichloromethane and ethyl acetate. The phytochemical study identified the presence of saponins, free anthraquinones, flavonoids and anthocyanidins. In evaluating the antibacterial dichloromethane fraction showed activity against all microorganisms tested both in agar diffusion test and microdilution test. The 70% ethanol extract showed activity against the micro-organisms S. aureus and S. epidermidis in agar diffusion test and against all microorganisms tested in microdilution test. The ethyl acetate fraction showed activity against the micro-organism S. aureus in the agar diffusion test and against all microorganisms tested in microdilution test. The end aqueous fraction showed no activity against any micro-organism tested. In the test of evaluation activity allopathic dichloromethane fraction showed greater inhibition of seed germination and growth of tomato (Lycopersicon esculentum Mill), followed by 70% ethanolic extract, the ethyl acetate fraction and the end aqueous fraction. In testing the antioxidant activity with DPPH ethyl acetate fraction showed higher antioxidant activity followed... (Complete abstract click electronic access below)
