Background: Marine sponges provided a great source of natural products with promising biological activity. This study was aimed to investigate the chemical constituents of methanol extracts of selected Indonesian marine sponges (Callyspongia sp., Clathria sp., Melophlus sarasinorum, and Xestospongia sp.), collected from the Saponda Islands, Southeast Sulawesi, Indonesia as well as to evaluate their antimicrobial and antioxidant activities. Methods: LCMS/MS analysis used to identify the compounds. Agar well diffusion and DPPH assays were used to evaluate the antimicrobial and antioxidant activities. Results: Chemical screening reported alkaloids, terpenoids, steroids, and saponins from all investigated sponges. The LC-MS/MS analysis identified various compounds which mainly contained steroids. Antimicrobial activity (against Bacillus subtilis, Escherichia coli, Salmonella enterica, and Candida albicans) was only shown by the Xestospongia sp. extract. Meanwhile, extracts of M. sarasinorum, Xestospongia sp., and Callyspongia sp. exhibited potent radical scavenging activity. Conclusion: The study concluded that the selected sponges could provide various groups of compounds. Methanol extracts of these sponges could be used as sources of antimicrobial and antioxidant agents.

A new megastigmane-type norsesquiterpenoid glycoside, chaemeloside (1), was isolated from the twigs of Chaenomeles sinensis together with 11 known phytochemicals through chromatographic methods. The chemical structure of the new isolate 1 was determined by conventional 1D and 2D NMR data analysis, ECD experiment, hydrolysis followed by a modified Mosher’s method, and LC–MS analysis. The characterized compounds’ biological effects including cytotoxicity against cancer cell lines, antineuroinflammatory activity, and potential neurotrophic effect were evaluated.

Around 3000 species of Saussurea are known, however Saussurea lappa Clarke which is perennial herb and has been traditionally used as anticancer, anti-inflammatory, antiviral, medicine without many adverse effects. Phytochemistry of Saussurea lappa after thorough literature survey revealed various varied and copious metabolites such as sesquiterpenes, flavonoids, phytosterols, lignans, terpenes. Many of these compounds have been found to possess a wide range of biological activity such as anticancer, anti-inflammatory, anti-hepatotoxic, anti-viral, etc. Among sesquiterpenes particularly Dehydrocostuslactone, dihydrocostunolide, costunolide Lappadilactone, have been isolated as the main chemical constituents. This review aims to cover published work from public databases (e.g. PubMed, Google Scholar, ResearchGate) and Non-English, Ph.D./MS thesis databases (e.g. CKNIChina, Jairo-Japan, Myto-Malaysia, Shodhganga-India) with a particular focus on phytochemistry and therapeutic uses of different fractions as well as isolated compounds from Saussurea lappa.
