A biorefining method of processing a lignocellulosic biomass to separate lignin and hemicellulose from cellulose includes the steps of (a) reacting the biomass in an aqueous slurry having a pH less than 7, comprising a transition metal catalyst, hydrogen peroxide; and (b) separating a solid cellulose fraction from dissolved lignin and hemicellulose fractions. The method may also be used to treat cellulose and produce microcrystalline or nanocrystalline cellulose. The transition metal catalyst may be a nanoparticulate catalyst including multivalent iron, iron oxides and iron hydroxides. The nanoparticulate catalyst may be formed by oxidizing a highly reduced solution of iron, such as groundwater that has not been exposed to oxygen.

Novel,saponin pharmaceutical compositions are disclosed. The,saponins are useful as immunological adjuvants to enhance immune responses to a co-administered antigen.

Polygala senega compositions and methods of use

Novel Quinoa saponin pharmaceutical compositions are disclosed. The compositions are useful for enhancing mucosal absorption of a drug administered therewith.

Quinoa saponin compositions and methods of use

Novel Quinoa saponin pharmaceutical compositions are disclosed. The compositions are useful as immunological adjuvants, to stimulate nonspecific immunity, as well as to enhance an immunological response to a selected antigen. The Quinoa saponin compositions can also be used to enhance mucosal absorption of a drug administered therewith.

Compositions and methods for modulating SRIF activity as well as enhancing the reproductive performance and immunological function in vertebrates are disclosed. Compositions containing SRIF-related peptides or antibodies thereto can be administered to animals to modulate endogenous SRIF-like activity. The SRIF-related peptides can be linked to a carrier such as ovalbumin, and administered in an Al(OH).sub.3 adjuvant, to enhance the immunogenicity of the SRIF-related peptides.
