Japanese Patent JPH0437802
Kind Code:
B2
Abstract:
PURPOSE:An antibacterial agent consisting of an L-ascorbic acid derivative, and, if necessary, a salt of a divalent transition metal. CONSTITUTION:An ascorbic acid derivative shown by the formula I (X1-3 is H, 2-21C acyl, polyfluoroacyl, or 7-21C aromatic acyl; at least one of it is not H) is used as an antibacterial agent. The acyl group in the formula I is generally shown by the formula II (R is 1-20C alkyl, polyfluoroalkyl, or 6-20C aryl). The antibacterial activity of the ascorbic acid derivative shown by the formula I is raised by the addition of a divalent transition metal (e.g., copper, iron, Mn, etc.). Especially a copper salt such as CuSO4, Cu(NO3)2, CuCl2, etc. is preferable.
