3-Methoxy-4-hydroxy cinnamic acid, 3,4-Dimethoxy cinnamic acid, 2,4-Dichloro cinnamic acid, 2,4-Dihydroxy cinnamic acid, 3,4-Dihydroxy cinnamic acid and 3-Nitro-4-methyl cinnamic acid were prepared, and their antimicrobial activities against the yeast (Kyokai No. 6 and Sacch. formosensis), molds (Asp. awamori and Rh. japonicus) and becteria (Bac. subtilis and Lact. delbrueckii) were examined.The results obtained are summarized as follows : -(1) 3-Nitro-4-methyl cinnamic acid showed a considerable inhibitory power against the microorganisms tested in this experiment.(2) The action of the five chemicals mentioned above, except 3-Nitro-4-methyl cinnamic acid, was not remarkably effective against the yeast and molds.(3) Both 3-Nitro-4-methyl cinnamic acid and 2,4-Dichloro cinnamic acid had remarkable inhibitory power against the bacteria.
