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.

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.
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:
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.
