ABSTRACT
A comprehensive comparison of fatty acid and metabolite profiles in 8 species of perilla seeds harvested from Korea and China was carried out to understand the correlation between cultivation conditions and the quality of perilla seeds. Metabolomic studies revealed that the perilla seeds were distinct from each other, based on the partial least squares -discriminant analysis (PLS-DA) score plots; 23 compounds including metabolites, fatty acids, and phytosterols that predominantly contributed to this interspecies difference were identified. Changes in the growth environment affected these compounds. In particular, phenolic compounds were affected by rainfall and temperature. Moreover, temperature and altitude showed negative and positive correlations, respectively, to oleic acid. Although more studies on the effect of various environmental factors on cultivation of perilla plants as well as their seeds are needed, the present results provide information that would be useful in identifying perilla seeds produced in specific regions and in the cultivation of good quality perilla.
