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.

values at 5% significant level.

Results showed that A.

circinalis was the most sensitive to alkaloid extract and the diameterinhibitionzone was 40 mm in 20 mg/ml concentration, while this alga was less sensitive to phenol extract anthe inhibition zone was 17 mm.

also the results showed that alkaloids extract was most active against all algae usedin this study followed by terpens extracts, while the phenols extracts had lower antialgal activity.
