Abstract: Provided is a method for coupling flavonoid-containing compounds to provide flavonoid dimers, trimers and oligomers. The method comprises contacting a flavonoid-containing compound with base in the presence of air. Flavonoid dimers, trimers and oligomers may also be useful in the treatment of diseases, such as fungal infections and diseases associated with starch hydrolase.

Abstract: The present invention relates, in general terms, to a method of extracting resin glycoside from a plant selected from the Convolvulaceae family. The resin glycosides can be extracted from Ipomoea batatas and/or Ipomoea aquatica.

Abstract: The present invention provides a novel catalytic system comprising catalysts immobilized on ultra-large mesoporous compositions, and particularly compositions having a large percentage of pores with a mean diameter of at least about 50 Å. Catalysts, such as organometallic complexes can reside in these pores to effect catalytic reactions. Such compositions include silicates covalently bound to a ligand that in turn can covalently bind an organometallic fragment. For asymmetric organometallic catalysts, the catalyst is bound to the mesoporous composition via an achiral ligand. The catalytic reactions include hydrogenation, hydroformylation, carbonylation and carbon-carbon coupling reactions, such as Heck or Suzuki reactions. The present invention provides catalyst for performing asymmetric reactions to achieve products of high stereoselectivities. The present invention also relates to ionically immobilized catalysts.
