It is commonly known as false daisy. The plant is used in Ayurvedic medicine for skin infections and some non-communicable diseases. Aqueous extraction of plant material such as leaf and whole plant were investigated for anti-microbial activity without changing concentration. Results of study revealed that all extracts had inhibitory activity against E.coli with the clear zone of 1.3cm, which is similar to streptomycin control. Antifungal activity of leaf and whole plant extract of Eclipta prostrata against Aspergillus and Rhizopus showed the inhibitory growth ranged from 23.5 % to 33.30% whereas the leaf extract showed high inhibition than whole plant extract. The findings exhibit that leaf and whole plant aqueous extracts have narrow spectrum activity and there is a possibility in treatment of infectious diseases.

Abstract: This study analyzed the flora, life form, and vegetation of the Nakdong River wetland. Vegetation analysis was performed on 37 plots using the phytosociological method of the Zürich- Montpellier School. PCA analysis was conducted by using the vegetation data (ground cover of class; 1~9) of 37 plots surveyed by phytosociological method. PCA (Principal Component Analysis) was used to statistically analyze the objectivity of the community classification and the character species. The traditional classification and mathematical statistic methods were used. A total of 82 taxa belonging to 28 families, 65 genera, 72 species, 2 subspecies, and 8 varieties were present in the vegetation of the survey area. The life form was analyzed to be the Th-R5-D4-e type.

Medit. 28: 145-153. 2018. — ISSN: 1120-4052 printed, 2240-4538 online. Floristic and phytosociological surveys in NE-Tunisia allowed to discover Eclipta prostrata (Asteraceae) which represents the first record at national level. A description of the species, notes on its ecology and phytosociological remarks are provided. We also stated, for the first time in Tunisia, the status of naturalization of three species (Erigeron bonariensis, Symphyotrichum squamatum, and Lepidium didymum) which does not appear still published until now. Key words: Alien species, Naturalization, North Africa. Introduction Invasions by non-indigenous plant species has become an important component of glob- al environmental change (e.g., Mack & al. 2000). Ruderal environments as well as coastal and riverine habitats have often been reported to harbor many neophytes (Sobrino & al. 2002; Bruno & al. 2004; Dark 2004; Von Holle & Motzkin 2007; Chytrý & al. 2007). Several studies of the coastal region of the Mediterranean Basin have shown a high degree of naturalization of introduced species (see e.g., Badano & Pugnaire 2004; Campos & al. 2004).
