Preliminary Data Regarding Pharmaceutical Forms Type Gels Based on Marine Algae Extracts with Antioxidant Activity

Abstract Particularly interest on herbs and plant extracts is due to their content of active principles with remarkable pharmacological properties. Different vegetal species contain natural antioxidants (polyphenols) used for dermatological anti-inflammatory healing activity, justified by action free radicals. The aim this paper was obtain selected phytopharmaceuticals formulations type gels an increased antioxidant potential based a mixture fluid from seaweeds in the phylum Chlorophyta, Cladophora vagabunda (L.) C. Hoek, family Cladophoraceae, Ulva lactuca syn. rigida (L.), Ulvaceae (sea lettuce) Rhodophyta, Ceramium rubrum Agardh, famiy Ceramiaceae, frequently presents along Romanian Black Sea coast. Fluid concentration 10% were obtained using cold maceration extraction method, solvents ethylic alcohol 40% 70%. mixed different ratio analysed physico-chemical properties, total phenols, chlorophylls, cartenoids, flavonoids antioxidative capacity photochemiluminescence method (ACL, Analytik Jena AG procedure). greatest polyphenols activity obtaining pharmaceutical forms which analyzed physical-chemical properties appearance, p H, spredability capacity. Preliminary results emphasized that proposed had appreciable correlated good stability, would represent possible new preparation.
