Abstract

After extracting the mori cortex by using three methods of Hot Water Extraction, 70% Ethanol Extraction and Hot Water Extraction after Extracting the Mori Cortex with LM which is a lactobacillus, antioxidant activity increased by 1.9 times in case of fermented mori cortex as a result of measuring antioxidant activity by using DPPH, and changes of SOD-like activity increased according as fermentation progressed as a result of measuring SOD-like activity per specimen 0.2 mL and showed the highest values second day or third day after fermentation. Through this experiment, we decided to use the Mori Cortex after 3 days` fermentation. Also in the measurement of B16-F10 cell viability of the morus alba extracts fermented for 3 days, the cell viability hardly had cytotoxicity as more than 80% also in the treatment concentration of 300
