Abstract

The aim of this study was to identify and evaluate for antimicrobial activity and phytochemical properties of the extracts from some plants belonging to different species such as Piper betle L., Allium cepa L., Allium ascalonium L., Allium Sativum L., Curcuma longa L.; Paederia tomentosa L.; Wedelia chinensis M. and Chromolaena odorata L. These extracts have been prepared and the antimicrobial activities have been examined on some bacteria strains like Escherichia coli T1, Bacillus cereus M1; Salmonella sp. ST; Shigella sp. AT and one fungus strain Aspegillus flavus KN by agar disc diffusion method. Results showed that the extracts from total of 8 plant species have been inhibited the growth of all over the micro-organisms strains used in the test at a different ratio, but the ethanol extracts from Piper betle and Wedelia chinensis M. showed the highest effect. Also, the extracts then were tested for the presence of bioactive compounds. The results showed that there were tannins, flavones, carbohydrates, proteins, and oils in Wedelia chinensis M.extracts. In Piper betle extracts there were many phytochemical compounds including phenols, tannins, saponins, carbohydrates, proteins, resins, and oils.
