The result shows that: the extraction of petroleum ether, polysaccharide and sodium copper chlorophyllin from banana leaves perform higher spumescence ability and foam stability. The critical concentration form pastern namely CMC and the surface tension in this concentration are 1.0 g/l (34.295 mN/m), 1.0 g/l (42.398 mN/m), 3.0 g/l (40.123 mN/m) respectively, which the value is close or excess the reference samples.
