Research articles on Tagetes erecta:
Anti- bacterial action: Antibacterial activity of different part of ethenolic extract of Tagetes erecta was evaluated using disc diffusion method against gram positive and gram-negative bacterial strains. Streptomycin (Standard) was used for antibacterial activity. The aim of this study was to evaluate the antibacterial activity of extract from this plant parts against 5 bacterial by using Disc Diffusion Method. The result indicates that the leaf and flower of this plant part showed a broad spectrum of anti-bacterial activity.
Anti- microbial activity: The aim of the present study was to extract active constituents of T. erecta flowers and evaluate their antimicrobial potential. The dried powder of the flower petals was extracted individually by the cold percolation method using different organic solvents like hexane, toluene, ethyl acetate, acetone, methanol and water. Out of the 8 Gram positive and 8 Gram negative strains studied, B. cereus and K. pneumonia were inhibited by all the solvent extracts except aqueous extract. Amongst Gram positive bacteria, highest antibacterial activity was seen against B. cereus followed by S. aureus and L. monocytogenes; while amongst Gram negative strains, highest antibacterial activity was seen against K. pneumoniae followed by P. pseudoalcaligenes.
Blood coagulation property: Blood clotting activity of leaf extract was examined using prothrombin time (PT) test by Owren method. Experiments showed that there was decrease in coagulation time with increase in extract concentration. Marigold leaves extract has shown very good blood coagulation property in lesser quantity i.e., in the range of ?l. Antifungal, antibacterial and antioxidant activity are also analyzed. From the above findings, it can be concluded that along with antibacterial, antifungal and antioxidant properties, marigold leave extracts are also having very good coagulation property.
Hepato- protective action: Current study focus on hepato protective activity of the roots in ethanol extract by ethanol induced hepato-toxicity model. Physical parameters, liver functioning, antioxidant levels and histo- pathological study of the liver were studied to find out hepato protective action of Tagetes erecta. Treatment with Tagetes erecta root extracts has protected liver from induced hepatotoxicity.
