  • Publication number: 20120178945
    Abstract: Disclosed are a method for preparing an n-hexane extract of the fruiting body of Antrodia cinnamomea (AC), wherein the fruiting body of AC is sequentially extracted with the ethanol solution and the n-hexane solution to obtain the n-hexane extract containing at least one benzenoid compound. The amounts of 4,7-dimethoxy-5-(3-methylbut-3-en-1-ynyl)-6-methyl-1,3-benzodioxole, 4,7-dimethoxy-5-methyl-1,3-benzodioxole, antrocamphine A and the combination thereof in the at least one benzenoid compound are determined using chromatography, NMR and HPLC. In addition, the present invention is applicable on detecting the amounts of benzenoid compounds in the AC healthcare food/drug or the fruiting body of AC, and thus owns the industrial values.

  • Publication number: 20120141524
    Abstract: A preparation method for an ethanol extract of the fruiting body of Antrodia camphorata (EEAC) is provided. The preparation method includes steps of: (a) providing the fruiting body of A. camphorata (AC); (b) extracting the fruiting bodies with a first ethanol solution; and (c) obtaining EEAC. EEAC further can be sequentially extracted or fractioned by n-hexane, ethyl acetate and ethanol, and an n-hexane fraction (FC), an ethyl acetate fraction (FA) and an ethanol fraction (FB) respectively are generated. The growth inhibition and apoptosis induction of leukemia cell line HL 60 are effectively mediated by FA product, in which zhankuic acid A is the bioactive marker. The amount of triterpenoid in the fruiting body of AC can be determined by NMR and HPLC analysis.

  • Publication number: 20110159127
    Abstract: The Toona sinensis extract of the present invention is prepared using supercritical fluid technique, wherein the method includes steps of: (a) drying the leaves of T. sinensis; (b) pulverizing the leaves as particles; and (c) extracting the particles with supercritical carbon dioxide to obtain the T. sinensis extract. This supercritical T. sinensis extract not only can decrease blood sugar level, but also promotes lipid degradation, inhibits the formation of huge lipid droplet and improves the metabolic symptoms. Accordingly, the T. sinensis extract further is able to be prepared as food supplement and pharmaceuticals.
