Abstract:
PURPOSE: A nonallergenic urushiol derivative is provided to maintain a structural basic skeleton of amphiphilic urushiol having a catechol structure that is a strong antioxidation active site and an oil soluble long side chain in the same molecule. CONSTITUTION: A nonallergenic urushiol derivative is a catechol type urushiol derivative represented by chemical formula 1. A veratro urushiol derivative is used in synthesis of the nonallergenic urushiol derivative and has a structure represented by chemical formula 2. In chemical formulas, R is CnH2n+1, wherein n is 6-9 or 16-19 chain type saturated hydrocarbon.
Abstract:
A method for preparing veratrol type and catechol type urushiol derivatives, and the their uses are provided to obtain an excellent antioxidizing activity. The veratrol type and catechol type urushiol derivatives prepared do not induce allergy with maintaining the structural basic frame of urushiol. Preferably the urushiol derivatives have a side chain comprising a saturated hydrocarbon.
Abstract:
The present invention relates to a malaxinic acid and a method for purifying the same and, more specifically, to a method for purifying a malaxinic acid containing an unripe pear characterized by being purified from an unripe pear, and to a malaxinic acid containing an unripe pear purified by the purifying method. The unripe pear contains plenty of malaxinic acid compared to a ripe pear. It is confirmed that the unripe pear is the optimal ingredient for purifying malaxinic acid by confirming that the content of malaxinic acid is reduced in an overripe pear.
