We report morphodiagnosis, and phytochemical and antimicrobial investigations of Tabebuia aurea. It was noted that the leaves are compostas with anomocytic stomata only on the lower side; the vascular system is concentric andthe mesophyll arrangement is dorsiventral. From the stem bark eight compounds were isolated, including: lapachol, 3,4',5-trihydroxy-7-methoxyflavone, b-sitosterol, betulinic acid, p-anisic acid, veratric acid, methyl cinnamate and ethyl p-hydroxy-cinnamate. Antimicrobial assays showed growth inhibition the of Gram positive and Gram negative bacteria, alcohol-acid bacterium and fungi.
