Results showed that two analogs,6 formyl 7 methoxyl 2,2 dimethy1 2H benzopyran and 7 hydroxyl 6 formyl 3,4 dihydro 2,2 dimethyl 2H benzopyran had higher inhibitory effects on two plants:radish and ryegrass than that of ageratochromene at concentration of 100mg/l,especially inhibited the root growth of plants significantly.They also possessed stronger antimicrobial activity and the inhibitory rates for two fungi( Rhizoctonia solani and Phytophthora capsici) were 100% at concentration of 400mg/l,moreover,7 hydroxyl 6 formyl 3,4 dihydro 2,2 dimethyl 2H benzopyran inhibited two bacteria species significantly: Xanthomonas oryzae pv. oryzae and Erwinia chrysanthemi at concentration of 2000mg/l.Researches revealed that 2,2 dimethyl 2H benzopyran,the basic structure of constituting ageratochromene was not correlated with its allelopathic and antimicrobial effecs.However,as there were active substituents at its 6 or 7 position,both effects were strengthen significantly. %K ageratochromene %K synthesis %K structural analog %K antimicrobial activity %K allelopathy
