Abstract: A process for concentrating and recovering water soluble glycosides from aqueous solution by foaming the solution, collecting the foam as a concentrated-in-glycoside product.
Abstract: Steryl-6-O-palnitoyl and -2,3,4,6-O-tetrapalmitoyl-.beta.-D-glucosides are anti-inflammatory agents. The compounds, of which .beta.-sitosteryl-2,3,4,6-O-tetrapalmitoyl-.beta.-D-glucoside is a representative embodiment, are prepared through the reaction of a steryl-.beta.-D-glucoside with a lower alkyl ester of palmitic acid in the presence of a basic catalyst.
