摘要:
Disclosed are a composition for preventing and treating atherosclerosis which includes chalcone compound. In particular, the chalcone compound bound with 2-hydroxyl in ring A and 4′-methyoxy in ring B has versatile therapeutic potentials on anti-atherosclerosis by acting as PPARγ inducer, p44/42 MAPK inhibitor and cell cycle blocker and does not show toxicity to human aortic smooth muscle cells (HASMCs). In addition, the chalcone compound exhibits synergistic effect with the PPARγ ligand (rosiglitazone) to inhibit cell proliferation and the upregulation of cyclin D1, cyclin D3, interleukin-1β (IL-1β) and interleukin-6 (IL-6) induced by oxidized low density lipoprotein (Ox-LDL).
摘要:
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.
摘要:
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.
摘要:
An optimal preparation and analytic method for the extraction of Antrodia cinnamomea is disclosed. The important parameters for the extraction efficiency of the extract are analyzed using mathematic and statistical experimental designs, and the extract of A. cinnamomea and its particular triterpenoid compounds are quantified and identified using the quantitative NMR and HPLC-tandem MS. Whether the ergostane and lanostane triterpenoid compounds are contained in one drug, health food or other products and the total amounts and individual amounts therein can be analyzed, determined or quantified using the techniques disclosed herein.
