  • Publication number: 20120052056
    Abstract: The present invention relates a composition containing, as an active ingredient, a post-fermented tea extract obtained by inoculating green tea with yeast as a fermentation strain and fermenting the inoculated green tea for a predetermined time. The composition has an excellent preference while it reduces the serum and liver cholesterol and triglyceride levels and has an excellent ability to relax blood vessels by inhibiting vasoconstriction, thus improving blood circulation. Due to its function to improve blood circulation, these compositions may be used as health foods, medical drugs and the like, which are effective against diseases, including stroke, myocardial infarction, hypertension, hyperlipidemia, diabetes or obesity.

  • Patent number: 7790836
    Abstract: Disclosed herein is a novel functional diamine compound having a dendron structure, polyamic acid which is produced using functional diamine, aromatic cyclic diamine, aliphatic cyclic acid dianhydride, and aromatic cyclic acid dianhydride, polyimide which is produced by imidizing polyamic acid, and an LC alignment film produced using polyimide. Even if the diamine compound is used in a small amount, it is possible to realize a high pretilt angle, thus the pretilt angle is easily controlled. Therefore, it can be used to produce an LC alignment film using a twisted nematic (TN) mode, in which the pretilt angle of liquid crystal is low, and a vertically aligned (VA) mode, which requires a high pretilt angle of about 90°.
