AbstractDespite the richness and biodiversity of invertebrates and algae in the Mediterranean Sea, these organisms are still poorly studied. The objective of our research is the discovery of bioactive lead compounds from the Mediterranean Sea sponge Hemimycale Collumella (HC). HC sponge (189.0 g) was collected from Mdiq costs on the Mediterranean Sea and extracted with methanol to yield (10 g) which was then subjected to fractionation. A bio-guided protocol was applied through evaluation of 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging and Oxygen Radical Absorbance Capacity (ORAC), α-amylase, β-glucosidase, pancreatic lipase inhibition as well as anti-collagenase, anti-elastase, antityrosinase and cytotoxic activity. 2,3-O-Hexahydroxydiphenoyl-(α/β)-glucose (1) and gentisic acid 2-O-β-glucoside (2) were isolated from the water fraction, quercetin-3-O-β-glucopyranoside (3), kaempferol 3-O-β-glucopyranoside (4) and isorhamnetin 3-O-β-glucopyranoside (5) from n-butanol fraction, gallic acid (6) from ethyl acetate fraction and gallic acid-3-methyl ether (7) from methylene chloride fraction. Compound 5 had the highest DPPH and ORAC activity. Compounds 1–5 had promising lipase inhibition activities which exceeded that of the standard Orlistat, while compounds 1–7 showed anti-tyrosinase activity higher than that of the standard Hydroquinone monomethyl ether. This is the first report for evaluation of the biological activities of 2, 3-O-hexahydroxydiphenoyl-(α/β)-glucose (1), gentisic acid 2-O-β-glucoside (2) and gallic acid-3-methyl ether (7).

Munronia is a genus in the Meliaceae family, which consists of over 17 species that are distributed in the subtropical and tropical area of Asia, including southern China, Vietnam, Myanmar, Sri Lanka, India, Indonesia, and the Philippines. It is known that these plants contain valuable bioactive compounds. Since the first isolation of new stigmastane steroid was reported in 2003, researchers have been able to study the chemical composition of these plants, especially the largest secondary metabolite obtained, limonoid. About 97 compounds were isolated successfully and characterized. The reported compounds showed various biological activities, such as antifeedant, antimicrobial, antiangiogenic, cytotoxic against several cancer cell lines, inducing apoptosis, and anti-tobacco mosaic virus activities. Therefore, the results suggest that the use of this plant as a source of bioactive compounds is promising for the medicinal chemistry field.

Elbamycellaroseasp. nov., introduced in the new genus Elbamycella, was collected in the Mediterranean Sea in association with the seagrass Posidoniaoceanica and with the brown alga Padinapavonica. The affiliation of the new taxon to the family Juncigenaceae is supported by both morphology and phylogenetic inference based on a combined nrSSU and nrLSU sequence dataset. Maximum-likelihood and Bayesian phylogeny proved Elbamycellagen. nov. as a distinct genus within Juncigenaceae. The new genus has been compared with closely related genera and is characterised by a unique suite of characters, such as ascospores with polar appendages and peculiar shape and dimension of ascomata and asci.

Abstract The composition of sterols, volatiles and some polar compounds from three Corallina samples (C. granifera and C. mediterranea from the Black Sea and C. mediterranea from the Mediterranean Sea) was established. The sterol composition of the Black Sea samples was similar but it differs from that of the Mediterranean sample. The composition of the volatiles was very complex. The main groups of constituent were hydrocarbons, alcohols, carbonyl compounds, acids and their esters, terpenes. The composition of the polar components, soluble in n-butanol, was also established. There were some differences in the chemical composition of the two Black Sea species, which may be due to the biodiversity between them, while the differences in the composition of the two C. mediterranea samples could be due to the differences in the environment (salinity, temperature, pollution, etc.).
