Evaluation of tinospora cordifolia willd. extracts against algal growth

الملخص EN

The present study has been conducted to evaluate the antialgal activities of Tinospora cordifolia leaves extracts, these extracts included Terpens, Alkaloids, and Phenols of that plant against 3 algal isolates: Anabaena circinalis, Scenedsmus quadricauda and Mougeotia scalaris.

The agar well diffusion method was used to evaluate the inhibitory actions of these extracts with 3 concentrations: 5, 10, and 20 mg/ml.

The experiments were conducted and analyzed as factorial experiments with three replications using a completely Randomized Design.

Means were compared according to L.S.D.

value at 5% significant level.

The results showed that Anabaena circinalis was the most sensitive to alkaloid extract and the diameter of inhibition zone was 40 mm in concentration of 20 mg/ml., while this alga was less sensitive to phenol extract and the inhibition zone was 17 mm.

The results also showed that alkaloids extract was the most active against all algae used in this study followed by terpens extracts, while the phenols extracts has the lowest antialgal activity.
