Objective: To investigate the steroidal glycoside constituents of Solanum cumingii.
Methods: The compounds were isolated by silica gel, Sephadex LH-20, RP-C18 column and Pre-HPLC chromatography. Their structures were identified by ESI-MS and NMR.
Results: Six known compounds including torvoside K (1), torvoside J (2), torvoside L (3), khasianine (4), aculeatiside A (5) and solamargine (6) were isolated from Solanum cumingii.
Conclusion: All compounds are isolated from Solanum cumingii for the first time.

To optimize the utilization of the sea star , which has demonstrated potential pharmaceutical properties in Chinese folk medicine, ten glycosides of polyhydroxy steroids, pectiniferosides A-J (-), were isolated and characterized. These compounds possess 3β, 6α, 8, 15α (or β), 16β-pentahydroxycholestane aglycones with sulfated and (or) methylated monosaccharides. The chemical structures of - were determined using NMR spectroscopy and HR-ESI-MS.

Four unreported pyridine alkaloids, curviflorines A-D (1-4), two undescribed iridoids, curviridoids A and B (5 & 6), and one known iridoid glycoside (7), were isolated from the twigs and leaves of Phlogacanthus curviflorus. The structures of these compounds were established by detailed interpretation of MS and NMR data, with the absolute configurations being assigned via comparison of experimental and calculated electronic circular dichroism spectra. Notably, it is the first report of alkaloidal constituents (1-4) from the genus Phlogacanthus.

Xylose, a key constituent of the heterogeneous hemicellulose polymer, occurs in lignocellulosic biomass and forms xylan polymers through β-1,4 glycosidic linkages. The β-1,4-xylosidase enzyme was isolated from Pseudopedobacter saltans (PsGH43) to find an effective enzyme with enhanced activity to depolymerize xylo-oligosaccharides. β-1,4-xylosidase belongs to the GH43 family as classified in the Carbohydrate-Active Enzyme Database (CAZy).
