Biological Activity and Chemical Constituents of Red and Brown Algae from the Persian Gulf
Different solvent extracts of a red algae, Hypnea flagelliformis,and two brown algae, Cystoseira myrica and Sargassum boveanum, collected from the Persian Gulf coast were subjected to different bioassays including: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (TLC)-bioautography, agar disc diffusion (ADD) ...

متن کاملChemical composition and biological activity of propolis from Brazilian meliponinae.
Twenty-one propolis samples produced by 12 different Meliponinae species were analyzed by GC-MS. Several chemical types of stingless bees' propolis could be grouped, according to the prevailing type of compounds like: 'gallic acid", "diterpenic" and "triterpenic" types. The results confirm that neither the bee species nor the geographical location determine the chemical composition of Meliponin...
متن کاملAntioxidant Activity of Otostegia persica (Labiatae) and its Constituents
The antioxidant activity of the different extracts and fractions of aerial parts of Otostegia persica (Burm.) Boiss. were evaluated using beta-carotene bleaching and lipid peroxidation methods. The inhibitory activity of the plant extracts on the peroxidation of linoleic acid were measured by ferric thiocyanate method in comparison to methanolic extracts of Green tee, Ginkgo biloba, Vit.E and ...
