摘要:
Disclosed are a method for analyzing chemical profiles of components from a herbal medicine product. Components may include quinone (including rhein, sennoside A and/or aloe-emodin), stilbene containing resveratroloside, flavone including baicalin, and/or alkaloid including berberine and/or palmatine. The method includes steps of: (a) respectively chromatographing a methanol extract of product and standard(s) corresponding to the component(s) using HPLC; (b) comparing HPLC chromatogram of extract and standard(s); and (c) analyzing the chemical profiles of the product from the comparison results.
摘要:
Disclosed is a chalcone composition for treating diabetes and metabolic syndromes. In particular, the chalcone compound bound with 2-halogen in ring A significantly decreases the blood glucose level in the in vitro anti-diabetic effect experiment. In the in vivo animal model, the leading chalcone compound can prevent the progression of diabetes and control the blood glucose level, and there is no significant difference in the gains in body weight. Throughout the seven-week administration, there are no hepatic or renal toxicity observed.
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:
An optical disk player includes a chassis, an optical pick-up head including a support member defining a guiding slot, and a guiding member molded integrally with the chassis, wherein the guiding member is received in the guiding slot and the optical pick-up head is slidably supported on the guiding member.
摘要:
A composition for treating cancer cells and a preparation method therefor are provided. The novel flavonoid compounds are obtained from natural plants, and more particularly the compounds have a cytotoxicity on cancer cells.
摘要:
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-γ production, and polarizes them toward the Th1 pathway. ACW can be effectively applied in cancer immunotherapy.
摘要:
A pharmaceutical composition, composed of protoapigenone (formula I), for treating gynecological cancers, prostate cancer, urinary bladder cancer and hepatocarcinoma is provided. Protoapigenone has cytotoxicity on these cancers, and arrests the cell cycle at S and G2/M phases. In addition, protoapigenone regulates cell signaling pathways, such as caspase-3, PARP, p-38 MAPK and JNK½, to induce apoptosis. Protoapigenone significantly inhibits the xenograft tumor growth on nude mice, without major side effects. Co-treatment o protoapigenone of protoapigenone and cisplatin shows synergistic cytotoxicity of MDAH-2774 ovarian cancer cells.
摘要:
New pharmaceutical compositions extracted from Ferula assa-foetida are confirmed to effectively treat influenza A (H1N1) virus. The extraction method of the new pharmaceutical compositions mainly includes steps of (a) extracting F. assa-foetida with methanol to obtain a crude extract; (b) fractioning the crude extract with n-hexane-methanol to obtain a methanol extract; (c) fractioning the methanol extract with chloroform-water to obtain a chloroform extract; and (d) chromatographing the chloroform extract to obtain the pharmaceutical compositions, which can be further fractioned and chromatographed to obtain various sesquiterpene coumarins.
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).
