L. root and root callus extracts of different
solvents viz., petroleum ether, chloroform, ethyl
acetate and ethanol were tested against both Gram positive
and Gram negative bacteria and also against Fusarium
spp. Root callus extract of chloroform and ethanol showed
significant activity against Bacillus subtilis, B.
cereus. Staphylococcus aureus, Staph.
epidermis and also against the other spp. of Gram
negative bacteria viz., Pseudomonas aeruginosa,
Klebseilla pneumonia, Alcaligens faecalis, Proteus vulgaris
Salmonella tyhimurium, Salmonella paratyphi A and Salmonella
subsp. enterica with a MIC of 3.12 to 12.50 μg/ml
when compared to root extract of chloroform, ethyl acetate
and ethanol of Trianthema decandra. Root callus
extract of chloroform, ethyl acetate and ethanol showed
activity against Fusarium verticilliodes, F. anthophilum,
F. oxysporum and F. proliferatum with a lowest
MIC of 3.12 μg/ml when compared to root extract of
Trianthema decandra. The result shows that antibacterial and
antifungal activity was more in root callus extract than
root callus extracts.
