초록

This study was conducted to examine the chemical composition of kiwifruit skin, and to est its anti-microbial activities and cytotoxicities, thus, exploring ways for the economic utilization of kiwifruit skin. Four varieties of kiwifruit were examined: Daeheung, Bidan, Haegeum No.1 and Hayward. Vitamin C content in the fruit skins of Bidan, Daeheung, Haegeum No.1 and Hayward were 72.44, 67.22, 62.51 and 61.44mg/100g, respectively. Total amino acids content in the fruit skins of Bidan, Haegeum No.1, Hayward and Daeheung ere 808.31, 706.02, 629.07 and 464.83mg/100g dry weight, respectively. K and Ca content ere $17.20-45.70{\mu}g/mL$ and $4.58-10.15{\mu}g/mL$. While, other inorganic matter contents were below $4.89{\mu}g/mL$. Anti-microbial activity of kiwifruit skin extracts, in terms of the diameter of inhibition zone when tested against five gram positive and three gram negative microbial trains (even in the concentration of 2,000mg/L), was less than 14.1mm. The hyperplasia inhibition of lung cancer cells by methanol extracts from Bidan and Haegeum No.1 using concentrations of 800mg/L were 27.7% and 14.5%, however, those from Daeheung and Hayward were below 3% Consequently, it will be useful to know that kiwifruit skin can be added to processed goods which demand for higher concentrations of vitamin C, amino acids, K and Ca.
