毛竹叶抑菌活性成分提取工艺研究

Abstract

Abstract: Extraction of active components from moso bamboo (Phyllostachys pubescens Mazel ex H. de Lehaie) leaves and their anti-microbial actives were studied. The minimum inhibitory concentration (MIC) of the active components from P. pubescens leaves against Staphylococcus aureus and Escherichia coli was determined by serial liquid dilution method. The results showed that anti-microbial effect of extracts from P. pubescens leaves against S. aureus and E. coli was optimum with the extraction condition: 60℃, 60% (volume fraction)ethanol, ratio of liquid to solid 20:1, 2h. The MIC of the extracts from P. pubescens leaves was 3.125g/L against S. aureus, and 6.25g/L against E. coli.

Key words: Phyllostachys pubescens Mazel ex H. de Lehaie leaves, extraction, anti-microbial activity, minimum inhibitory concentration
