  • Patent number: 10314847
    Abstract: The present invention discloses scalarane sesterterpenoids represented by formula (I) and meroditerpenoid represented by formula (II), which are extracted from Carteriospongia sp. sponge: where R1 is —CH3 or —C2H5. The compounds of formula (I) can be used to be an anticancer, act as an inhibitor targeting to topoisomerase II and hsp90 and a pharmaceutical composition for anticancer.

  • Publication number: 20170226150
    Abstract: Disclosed are the isolation, purification and analysis of the triterpenoid compositions (including ergostane and lanostane) in the fruiting body of Antrodia cinnamomea using HPLC and NMR, as well as the stereo structures and the amounts of the triterpenoid compositions. The cytotoxicity of triterpenoids is also revealed. Based on the aforementioned techniques, the presence and amounts of ergostane and lanostane in the drugs, healthcare food or other goods are able to be detected.

  • Patent number: 9241962
    Abstract: A preparation method for a water extract of the fruiting body of Antrodia camphorata (ACW) is provided. The method includes steps of: (a) providing the fruiting body; and (b) boiling the fruiting body in water to obtain the water extract. This polysaccharide-rich water extract from A. camphorata induces the maturation of dendritic cells, enhances T cell proliferation and INF-? production, and polarizes them toward the Th1 pathway. ACW can be effectively applied in cancer immunotherapy.

  • Patent number: 8883167
    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.

  • Patent number: 8716499
    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.
