Details	Cultivation experiments of a perilla (P. citriodora)have been performed for 3 years. The composition of oil component of the yearly obtained seeds was analyzed. α-linolenic acid, linoleic acid, oleic acid, saturated fatty acid and γ-linolenic acid were contained percent weight in descending order. The percent weight of α-linolenic acid in P. citriodora was as high as those of other two commercially available perillas. The diameter length of P. citriodora was smaller with statistical significance (p<0.01). The weight percent of the total oil component in P. citriodora was 25.41±0.87. The value of cadmium to zinc (Cd/Zn), which indicates the accumulation rate of the two metals from farm soil into seed was 0.015±0.001, which was the smallest among the plant body parts. Research cultivation and characterization of P. citriodora would contribute for the evaluation of the local biological environment including humans.
