Abstract
Background: Since the dawn of civilization, humans have utilized herbs for their medicinal value which are used as a traditional medicine that has stood up to the test of time and for the production of many novel prototypes. Objectives: The study aims to the exploration of medicinal weeds in the agroecosystem of Savandapur village in Gobichettipalayam, Erode District, Tamil Nadu and to investigate the phytochemical compounds and antimicrobial activity of the selected study plant. Materials and Methods: The documentation of medicinal weeds was carried out with the help of traditional local healers in the paddy fields of Savandapur village. Pharmacognostical studies of selected study plant were followed by standard procedures and antibacterial assay has been done by well diffusion method. Results: A total of 22 species of common weeds distributed across 21 genera and 13 families were identified. Among these, due to its high therapeutic value, Ammannia baccifera L. is evaluated for its potentiality. The aerial plant part contains the phytoconstituents such as carbohydrate, alkaloid, flavonoid, phenol, tannin, glycoside, terpenoid, saponin, coumarin and fixed oils. T.S of stem shows the calcium crystals and oil globules. The petroleum ether and methanolic extracts were active against the tested microorganisms Staphylococcus aureus (gram-positive) and Pseudomonas aeruginosa (gram-negative) and also aqueous extract has no antibacterial activity. The methanolic extract has a high degree of potentiality which is more relevant to the antibiotic Kanamycin. Conclusion: The investigation reveals the importance of weeds in the paddy field ecosystem. Further, the evaluation of the antibacterial properties of these extracts and isolation of the compounds responsible for the antibacterial activity is required.
