Abstract

Natural grape extraction was extracted from grape component using diethyl ether as a solvent, and we tested various pharmaceutical and chemical characteristics of this extract. Characteristic experiments to use natural grape extract tested antimicrobial experiment using microbe in pharmaceutical material, and tested dye experiment using fiber in chemical material. From the result of characteristics experiment, some conclusions are obtained as follow. From the result of characteristics experiment, it obtained about 7.5%-grape extraction ratio as semi-solid state, and after dried in freezing from grape extract of semi-solid state, it obtained about 10%-grape extraction ratio as solid state of dark purple color. From result of antimicrobial experiment of grape extract, number of staphylococcus aureus (KCMC-01) and aspergillus niger (KCMC-02) in microbe decreased more and more according to time passage. This phenomenon showed that grape extract influences to antimicrobial effect. From the result of dye experiment of grape extract, it appeared in direction of dark purple color after dyed to use cotton and silk with fiber to control in pH 7.5. Specially the result which confirmed dye of fiber with optical electron microscope(OEM), we could know that it appears darker silk than cotton.
