摘要： The characteristics of anti-fungal activity to Alternaria alternate of three fractions of water, ethyl acetate, petroleum ether of sunflower discs and stalks have been studied. The fractions of water, ethyl acetate, petroleum ether of sunflower disc and petroleum ether fraction of sunflower stalk have good anti-fungal activity to A. alternate. The best concentrations of anti-fungal activity to A. alternate of water, ethyl acetate, petroleum ether fractions and petroleum ether fraction of sunflower stalk were 320 mg/mL, 240 mg/mL, 160 mg/mL and 160 mg/mL, respectively. The anti-fungal activities to A. alternate of these four kinds of extract are increased with the increase in concentration and arrive at stability after the best concentration of anti-fungal activity to A. alternate. The ethyl acetate fraction and petroleum ether fraction of sunflower stalk had no anti-fungal activity to A. alternate.
