Biological activities of the red algae and butters.

The biological activities; antimicrobial, antioxidant and anticancer, of the red algae and were determined. The total ethanol, lipoidal matters, chloroform, n-butanol, aqueous extracts and powder of both algae showed and bacterial and antifungal activities. However, the chloroform extract of showed antibacterial activity against (24 mm, 0.15 mg/ml) higher than gentamycin (23 mm, 0.49 mg/ml). Moreover, the total ethanol, lipoidal matter and chloroform extracts showed antifungal activity (21, 22 and 25 mm, 1.25, 0.312 and 0.156 mg/ml) similar to the antibiotic Ketoconazole activity (23, 24 and 27 mm, 1.25, 0.312 and 0.156 mg/ml) against , and , respectively. A good antioxidant activity (80.96%, IC = 27.8 µg/ml) was provided by . The anticancer activity results revealed that the lipoidal matters of and possessed antitumor activity (IC = 15 ± 1.7 and 21.2 ± 1.6, respectively) against lung carcinoma (A-549) better than vinblastine sulfate (IC = 24.6 ± 0.7). Although, the lipoidal matters of and antitumor activity against cervical carcinoma (HeLa) and intestinal carcinoma (CACO-2) (IC = 10.2 ± 0.6 and 12.2 ± 0.6, respectively) preferable than vinblastine sulfate (IC = 59.7 ± 2.1 and 30.3 ± 1.4, respectively).
