摘要：

Callus culture of Tridax procumbens has been established on Murashige and Skoog's medium supplemented with NAA and BAP from nodal segments. Free and bound flavonoids were extracted from 2, 4, 6 and 8 weeks old calli by a well-established method. These free flavonoids were then screened against Staphylococcus aureus (bacteria) and Candida albicans (yeast) for their antimicrobial potential. Minimum inhibitory concentration, minimum bactericidal/ fungicidal concentrations and total activity were also evaluated. Apigenin, quercetin and kaempferol were identified from free flavonoids of 4 weeks old callus (most active) through, thin layer chromatography, (TLC) preparative TLC, MP and IR spectral studies.
