	abstract = {<p>Turmeric is the processed underground rhizome used as spice, herbal medicines, dying agent and cosmetics. The leaves and rhizomes of this plant were collected at periodic intervals. These samples were air dried, powdered and extracted with MeOH and EtOH. Antibacterial activity of these extracts was determined against three different index microbes, gram-positive cocci, gram-negative rod and cocci using well diffusion method with appropriate controls. Antimicrobial activity of the 4-month-old leaves was found to be the maximum while that of mature and fresh rhizomes was the maximum against both gram-positive and Gram-negative bacteria.</p>},

	abstract = {<p>The antibacterial activity of Linolenic SL mixture (containing 80\% lactone) and its methyl ester derivative against Gram positive (B. subtilis) and Gram negative (E. coli and P. aeruginosa) bacteria is reported here. Bacterial cultures were treated with increasing concentrations of Linolenic SL mixture and its methyl ester derivative and antibacterial activity was checked at different time-intervals (2, 4 and 6 hrs) using standard dilution micromethod and spread plate method. Decrease in bacterial colonies was observed with increase in concentrations of compounds as well as incubation time but the level of effectiveness varies with the compound and bacteria. The minimum inhibitory concentrations (MIC) of Linolenic SL mixture (LNNSL, containing 80\% lactone) against B. subtilis, E. coli and P. aeruginosa were found to be 20, 10 and 10 mu g ml(-1) respectively. The MIC values of methyl ester form (LNNSLME) against B. subtilis, E. coli and P. aeruginosa were determined to be \&gt;20, 20 and 20 mu g ml(-1) respectively. The results suggest that Linolenic SL mixture (containing 80\% lactone) as compared to its methyl ester derivative showed good antibacterial activity towards both the Gram positive and Gram negative bacteria and were found to be more potent against Gram negative bacteria.</p>},
