The antibacterial activity of waltherione-A, isolated from Waltheria douradinha (Sterculiaceae) (Table IX) and its O-methylated derivative were evaluated by means of direct bioautography in a TLC bioassay. The former alkaloid was not active against all bacteria tested (S. aureus. Streptococcus epidermidis. Micrococcus luteus, Klebsiella pneumoniae. Salmonella setubal, and E. coli), while its O-methyl derivative was active against all of them. The detection limits were 25.0, 3.5, 6.5, 12.5, 12.5, and 6.5 pg, respectively (170). [Pg.191]
