영문 초록

This research has been undertaken to increase availiability of native Camellia japonica leaf and flower in Korea as a edible-medicinal resource. Chemical compositions, antioxidant and antimicrobial activities in different parts of camellia were investigated. Crude protein contained the highest in young leaves(14.22%) but less than 10% in different parts. The contents of crude fat and crude ash were 60.48% in seeds and 5.16% in mature leaves, respectively. Methanol extract of young leaf, flower, and flower bud in camellia showed strong antioxidant activity compared with different parts. Also, antioxidant activity of these was higher than that of BHT, but weaker than that of VtC. Antioxidant activity of various parts in camellia were in order of young leaf ＆gt; flower bud ＆gt; flower ＆gt; mature leaf ＆gt; stem ＆gt; bark. Extracts of mature leaf and bark had a remarkable antibacterial activity(0 CFU/㎖) on Bacillus subtilis. The young leaf extract displayed effective growth inhibition against B. subtilis, Candida albicans, and Trichosporon beigelii.
