Open publisher page 1 citations

Abstract

An orthogonal experiment was carried out to confirm the optimum extracting technology for the flavones from the bamboo leaves.The results showed that the optimal conditions were 75% of volume fraction ethanol solution,extraction temperature at 70 ℃ for 1.5 h and liquid-solid ratio of 20∶1.Under this condition,the extracting yield of flavones was the best.Additionally,the anti-microbial testing of the flavones showed that the anti-microbial activity to the bacterium was obvious,but it was not so effective to yeast and mould.
