Processes for making caralluma extracts and uses

摘要

Abstract This invention provides Caralluma extract products that are standardised, representative of the caralluma plant material from which they are derived, are reproducible and which form suitable starting materials (intermediates) for the medicinal, nutraceutical and food products of caralluma and which are, furthermore, suitable for direct administration to subjects. The invention also provides a process for making a composition for medicinal, nutraceutical and food applications, that chiefly comprises one or more pregnane glycosides, from plant matter wherein the nature of the solvent/solvent mixture for extraction and the conditions of extraction and of concentration of the extract are selected such as to prevent/minimise the decomposition of said glycosides and the simultaneous extraction of non-glycoside matter such as pectins, tannins and the resinous matter contained in said plant matter.
