  • Patent number: 9259396
    Abstract: The present invention relates to a method of preparing a solid form of soy isoflavone (e.g. genistein). In particular, the present invention relates to a method of preparing a solid form of soy isoflavone by precipitation with compressed antisolvent using a supercritical fluid to produce nano-sized particles of soy isoflavone with an improved dissolution rate and bioavailability. An oral composition or aerosolized formulation comprising the nanoparticles of the soy isoflavone prepared by the method of the present invention is also disclosed herein. The dissolution rate and bioavailability of the nanoparticles of the soy isoflavone prepared by the method of the present invention have a 2-fold increase and a 2.6-fold increase respectively as compared to those of the raw soy isoflavone.

  • Patent number: 8916369
    Abstract: A maltogenic a-amylase from Trichoderma reesei (TrAA) and variants thereof are useful in the production of high-maltose syrups from liquefied starch. Particularly high maltose concentrations are achieved when TrAA is used in the presence of a pullulanase. Expression hosts and encoding nucleic acids useful for producing TrAA and its variants also are provided.

  • Patent number: 8765439
    Abstract: A maltogenic ?-amylase from Trichoderma reesei (TrAA) and variants thereof in the presence of a glucoamylase are useful in the production of high-glucose syrups from liquefied starch, where the high-glucose syrups produced thereby contain at least about 97% glucose. In this process, TrAA advantageously suppresses the reversion of glucose to malto-oligosaccharides. Expression hosts and encoding nucleic acids useful for producing TrAA and its variants also are provided.

  • Publication number: 20130280774
    Abstract: Provided herein are compositions and methods related to the direct conversion of the starch in a ground or fractionated grain into a fermentable sugar feedstock capable of serving as a carbon source for the industrial production of one or more products by a fermenting organism, such as isoprene, isoprenoid precursor molecules, and/or isoprenoids. Such conversions may be performed at temperatures at or below the initial gelatinization temperature of the starch present in the grain and may utilize one or more isolatable endogenous enzymes present in certain unrefined grains.

  • Publication number: 20110301236
    Abstract: A novel compound isolated from the plant Garcinia paucinervis. The compound's structure is as follows: The compound possesses a potent ability to activate caspase-3 in HeLa-C3 cells within 72 h at a low concentration of 25 ?M. The IC50 on HeLa cells for this compound was measured to be below 10 ?M, indicating a strong HeLa cell growth inhibitory effect.

  • Publication number: 20110301233
    Abstract: Novel polyisoprenylated benzophenone derivatives isolated from the plant Garcinia paucinervis. Among these new compounds, paucinones A-C (Compounds 1-3) contains an unexpected cyclohexane-spiro-tetrahydrofuran moiety. A 1-methylene-3,3-dimethylcyclohexane group never reported before was found in the structure of paucinone D (Compound 4). Structures of these compounds were elucidated with spectroscopic evidence. The relative stereochemistry of 1-4 was determined by NOESY correlations. These compounds a potent ability to activate caspase-3 in HeLa-C3 cells within 72 hours at a low concentration and significant cytotoxicity against HeLa-C3 cells.
