The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.
