The present invention relates to salts of (R)-3-(6-(4-methylphenyl)-pyridin-3-yloxy)-1-aza-bicyclo[2.2.2]octane, to methods for making them or their precursors, to pharmaceutical compositions comprising them, and to their use as medicaments.

Provided are methods or processes for producing ferulic acid from a plant material, for example, a rice bran or its derivatives. Provided are methods comprising an ion swapping and solvent extraction process followed by a chromatographic separation operations that are coupled into a process which functions to recover a fraction rich in gamma-oryzanol, thus enabling the subsequent production of a high purity ferulic acid. Provided are methods comprising an ion swapping and solvent extraction process followed by a process which functions to recover a fraction rich in gamma-oryzanol, or a mixture of ferulic acid esters of phytosterols and triterpenoids, optionally comprising cycloartenyl ferulate, 24-methylenecycloartanyl ferulate, and/or campesteryl ferulate, to enable the production of a high purity ferulic acid. Provided are methods comprising a saponification and solvent extraction process followed by recovering a fraction rich in gamma-oryzanol to enable the production of a high purity ferulic acid.

According to this method, a fatty acid of CnH.sub.2nO.sub.2 (n=5 to 14) is mixed with a plurality of metal sources selected from Zn, In, Sn, Sb, and Al, thereby fatty acid metal salts are obtained, subsequently the fatty acid metal salts are heated at 130° C. to 250° C., and a metal soap that is a precursor is obtained. This precursor is heated at 200° C. to 350° C., and metal oxide primary particles are dispersed in the precursor melt. To this dispersion liquid, a washing solvent having a δP value higher by 5 to 12 than the δP value of the Hansen solubility parameter of the final dispersing solvent is added, thereby the metal oxide primary particles are washed and agglomerated, metal oxide secondary particles are obtained, and then washing is repeated.
