Constituintes químicos de Lippia sidoides (Cham.) Verbenaceae

Thirteen compounds, 3-O-acetyloleanolic acid (1), methyl 3,4-dihydroxy benzoate (2), lapachenol (3), tecomaquinone (4), tectoquinone (5), tectol (6), acetilated tectol (7), quercetin (8), luteolin (9), glucoluteolin (10), lippisidoquinone (11), taxifolin (12) and isolariciresinol (13), were isolated from ethanol extract of Lippia sidoides. Their structures were assigned unambiguously by a combination of 1D and 2D NMR, IR and EIMS spectral data analysis and comparison with the published data for structurally related compounds. In brazilian traditional medicine the aerial parts of this specie are used as anti-infective agent, particularly as antiseptic.
