Title: Process for recovering saponins from agave leaves
IPC: C07J75/00
Filed: 1962-11-08
Abstract: Saponins and sapogenins are recovered from the non-fibrous matter of agave leaves with the simultaneous recovery of non-saponic organic and mineral matter by producing from said non-fibrous matter an extract with an aliphatic alcohol having not more than 6 carbon atoms or a mixture of organic solvents containing at least one such alcohol, recovering at least part of the non-saponic organic and mineral matter from the alcohol extract, and thereafter recovering saponins and sapogenins from the alcoholic extract, for example by further processing hecogenin may be isolated from the extract. The juice expressed from agave leaves may be used as the starting material in which case the juice may be either concentrated to a dry matter content of 50-70% (any precipitated non-saponic organic and mineral matter may be separated) and the remaining syrup is submitted to the above extraction process, or allowed to separate into a slurry and a supernatant clear solution, the latter solution is removed and the former slurry is used with or without further concentration in the above extraction process. The dry matter obtained by drying the juice and/or flesh of the agave leaves may be used in the above extraction process, for example using an azeotropic mixture of benzene and methanol. The removal of at least part of the non-saponic organic and mineral matter from the alcoholic extract may be effected by back extraction of the extract with a non-polar organic solvent such as petroleum ether, benzene and toluene, followed, if desired, by recovery of the non-saponic organic and mineral matter, or by filtration and/or centrifugation. After the recovery of the saponins and sapogenins, non-saponic organic and inorganic mineral matter may be recovered from the alcoholic extract.  The quantity of sapogenins in the final extract depends on whether prior and/or during the extraction.ALSO:Poultry feed additives containing inter alia lipoids various minerals chlorophyll, proteins and carotenoids are obtained as less soluble matter in an extract formed from the non-fibrous matter of agave leaves and an aliphatic alcohol having not more than 6 carbon atoms or a mixture of organic solvents containing at least one such alcohol.  The non-fibrous matter used in the above process may be the juice of the leaves or the material obtained by evaporating the juice to dryness, or the flesh of the leaves, or an aqueous diluate of the juice which may be concentrated for the extraction process in which case the solid material which separates out may be separated and used as a poultry feed additive (having approximately the same constituents detailed above).  The poultry feed additive may also be isolated from the alcohol extract by back extraction with a non-polar solvent such as petroleum ether, benzene and toluene.
