Abstract
The objective is to test the antifungal activity of extracts from Myrica rubra leaves and myricetin.Based on a preliminary test for inhibition of acetone extracts from leaves of Myrica rubra,the fungi Rhizoc-tonia solani,Sclerotinia sclerotiorum,Botrytis cinerea,Fusarium graminerum,Valsa mali and Fusarium oxysporum f.vasinfectum were selected and their mycelium growth rate were tested in five concentrations(among 5,10,20,30,40,50,and 60 g.L-1).Antifungal activity was also tested with pure myricetin acetone solution in five concentrations(among 0.30,0.40,0.50,0.60,0.70,and 0.80 g·L-1).Results showed that when restraining effect were 50%,concentrations of extracts from leaves of M.rubra were(in g.L-1) R.solani(23.08),S.sclerotiorum(19.85),B.cinerea(25.86),F.graminerum(22.07),V.mali(23.18),and F.oxysporum f.vasinfectum(22.86).Meanwhile,when inhibition was 50%,concentrations with pure myricetin acetone solution for the same fungi were 0.32,0.33,1.09,0.69,0.34 and 2.09 g·L-1 respec-tively.A stronger effect of 10 times the diluent from leaves of M.rubra showed a therapeutic action 42.3% and a protective function 45.6% on tomato.
