Constituintes químicos e atividade antimicrobiana dos extratos de Dilodendron bipinnatum (sapindaceae)

The phytochemical investigation of ethanolic extracts from leaves, branches and stems of D. bipinnatum afforded the steroids β-sitosterol, stigmasterol, campesterol, sitostenone and sitosterol-3-O-β-D-glycopyranoside, along with two cycloartane triterpenes: cycloeucalenol and 24-methylenecycloartenol. The antimicrobial activity of the extracts was evaluated against Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922), Bacillus subtilis (ATCC 6623), Pseudomonas aeruginosa (ATCC 15442), Micrococcus luteus (ATCC 9341) and Candida albicans (ATCC 10231). The extracts of the leaves and branches showed moderate activity against Candida albicans. The extract of the branches was active against Micrococcus luteus. This is the first report on the phytochemical study of D. bipinnatum.
