Abstract

|
For the physiological and antibacterial activity test, bamboo(Pseudosasa japonica Makaino) leaves were extracted with 70% ethanol at 80±2℃ and fractionated it with 4 solvents which had a different polarity. Seventy percent ethanol extract from bamboo leaves showed strong antioxidative activities toward the linoleic acid methyl ester substrate. In each fraction obtained from 70% ethanol extract, inhibition activities against lipid peroxide and malonaldehyde formation were increased in the order of aqueous fraction ＜ n-butanol fraction ＜ petroleum ether fraction ≤ diethyl ether fraction ≤ ethyl acetate fraction. The electron donating abilities, nitrite-scavenging abilities and anti-complementary activities of n-butanol fraction were the strongest of all the fractions. The 70% ethanol extract showed relatively high electron donating abilities, nitrite-scavenging abilities and anti-complementary activities. Furthermore, the 70% ethanol extract showed strong antibacterial activities against microorganisms related to food hygiene such as Vibrio parahaemolyticus, Pseudomonas aeruginosa, Salmonella typhimurium, Enterobacter aerogenes and Staphylococcus aureus.
