The antibacterial activity of Eclipta alba against three gram positive and five gram negative bacterial strains was investigated. The fresh whole plants were collected from Chidambaram, Tamil Nadu. Petroleum ether, chloroform, ethyl acetate, acetone, methanol and aqueous extracts at different concentrations (1, 2, 5, 10 mg/ml) were used to investigate the antibacterial activity. NCCL standards were strictly followed to perform antibacterial disc susceptibility test using disc diffusion method. The extracts showed varying degree of inhibitory potential against all the tested bacteria. Methanol extract of the plant had higher inhibitory action against Staphylococcus aureus, Bacillus subtilis, Proteus mirabilis and Pseudomonas fluroescens.

An efficient protocol has been developed for rapid in vitro propagation of Eclipta alba L. (Asteraceae) through axillary bud multiplication. Murashige and Skoog (MS) medium supplemented with BA (10 pM) was found to be most effective in breaking bud dormancy. An average number of 23 ± 0.57 shoots per explant was recorded after 30 days. Culture of node segments on fresh medium with lower concentration of BA (2 pM) enhanced the multiplication rate. A maximum of 79 ± 1.90 mean number of shoots were obtained after three subcultures without any decline in multiplication rate. The regenerated microshoots showed the most efficient rooting on half strength MS medium augmented with 0.5 pM IBA. Plantlets went through a hardening phase prior to ex vitro transfer and established in earthen pots containing garden soil; survival of about 90 %. The established plants were uniform and exhibited morphological characters identical to mother plants.
