The study of ethno botanical was carried out along with the ethnic groups (Villupuram district) in the South Western Ghats of India. In the present study, 46 plant species belonging to 31 families were included. In this assertion, the information collected from the traditional healers was used to compare with the already accessible literature on the ethnobotany of India. The conventional ethno medicinal plants were mostly used for fever, dysentery, skin diseases, poison bites, wounds, piles and rheumatism. The medicinal plants used by traditional users of Villupuram district are arranged alphabetically followed by botanical name, family name, local name and major chemical constituents, parts used, mode of preparation and medicinal uses.   Key words: Medicinal plants, traditional healers, chemical constituents

The aim of the present study was to identify the bioactive compounds and to investigate the antibacterial activity from the leaves of Tridax procumbens. The antibacterial activity of T. procumbens phytochemical extracts was determined by agar disc diffusion and minimum inhibitory concentration (MIC) against Staphylococcus aureus, Escherichia coli, Proteus mirabilis, and Vibrio cholerae. The phytochemicals of the plant extract were analysed by thin layer chromatography (TLC) and antibacterial compounds were determined by TLC-bioautography. Furthermore, the structural elucidation of the antibacterial compound was confirmed by IR, Mass spectrum and NMR. Significant inhibitory activity was observed with terpenoid extract of the plant against the test bacteria while less antibacterial activity was observed in alkaloid, flavonoid and glycoside extracts. Terpenoid compound treated microbes resulted in the leakage of reducing sugars and proteins through the membrane. It also induced the act...
