Theextract of the present invention is prepared using supercritical fluid technique, wherein the method includes steps of: (a) drying the leaves of; (b) pulverizing the leaves as particles; and (c) extracting the particles with supercritical carbon dioxide to obtain theextract. This supercriticalextract 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, theextract further is able to be prepared as food supplement and pharmaceuticals.

Extract offrom supercritical fluid extraction for treating diabetes and metabolic disease, the preparation method and the use thereof

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 PPAR&#x3b3; 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 PPAR&#x3b3; ligand (rosiglitazone) to inhibit cell proliferation and the upregulation of cyclin D1, cyclin D3, interleukin-1&#x3b2; (IL-1&#x3b2;) and interleukin-6 (IL-6) induced by oxidized low density lipoprotein (Ox-LDL).

Composition for treating atherosclerosis and a preparation method thereof

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.
