Abstract: Using micocalorimetric method. we stueide the fundamental growth thermograms of two bacteria with the extractions of glossy ganoderm, beet tea,and epigallocotchin-3-gullate existed. respectively. Frompictorial graph, we can clearly see these extractions have good antifungal activity. So it is certain that these natural activating ingredient are very useful an antifungal and natural food preservatives．
