It is known that the rice cultivar, Sasanishiki, is susceptible to race 033 of the rice blast fungus, which is reported to produce the anti-fungus material when suffered from the disease. On the other hand, growth of infection hyphae of the same race is inhibited in the invaded cell of the resistant variety as typified by the cultivars, Fukuyuki and Fukunishiki. The present study deals with the defense mechanism of the rice plant against rice blast fungus by isolation of antifungal components from the above mentioned three kinds of rice plants. From the uninfected Fukuyuki were isolated active compounds summarized in the table 3 and 4. It was revealed that the infected Sasanishiki and uninfected Fukunishiki produced active compounds (13-16) in addition to the epoxides and allyl alcohols (1-12) from the active portions. It is reasonably speculated that these active compounds, the oxygenated unsaturated fatty acids, are produced in the Sasanishiki after infection, in the meanwhile the resistant varieties such as Fukuyuki and Fukunishiki produce these active compounds before the infection as defense substances.
