English Abstract
This study includes isolation, purification, and identification of algae from different aquatic environments in Baghdad city.
Nine unialgal cultures were obtained.
These algal cultures included 6 species of blue-green algae (Microcystis aeruginosa, Microcystis flos-aquae, Oscillatoria limnetica, Nostoc carneum, Westillopesis prolifica, Mastigocluds lamiosus), and 3 species of green algae (Mougeotia sclaris, Scenedesmus dimorphus and Chlorella vulgaris).
In addition, aerial parts of 3 plant species belonging to different families were collected (Convolvulus arvensis L, Plantago lanceolata L and Euphorbia granulata F).
Terpens, alkaloids, phenols were extracted from mentioned plants aerial parts.
The antialgal activity of the extracts were evaluated in 3 concentration (5, 10, and 20 mg/ml) by agar wells diffused method .
Results showed that phenols extracts from all mentioned plants were the most effective against isolated algae than other extracts, and terpens extractes were less effective.
O.
limentica was the most sensitive to attack by extracts than other algae, N.
carneum was less sensitive.
W.
prolifica, M.
lamiosus were the most resistance to attack by C.
arvensis and P.
lanceolata extracts.
Results showed that the algae W .prolifica, M.
sclaris were the most resistance to attack by the E.granulata.
The compounds which isolated from C.arvensis were the most effective against algae.
But the isolated compounds from P.
lanceolata were less effective.
Chemical composition of phenols and alkaloids were analyzed by High Performance Liquid Chromatography (HPLC) and showed that 10 phenolic compounds, 8 alkaloid compounds in C.arvensis were present, 7 phenolic compounds, 3 alkaloid compounds in P.
lanceolata, 8 phenolic compounds, 5 alkaloid compounds in E.
granulata.
Finally, results showed that C.
arvensis contain the highest amount of phenols and alkaloids from other plants, while P.
lanceolata contained lower amount.
All the active isolated compounds were not recommended to control algae due to the ability of these compounds to lyse algal cell wall and make release toxins to surround water is possible
