We investigated the fatty acid composition and regiospecific distribution of triacylglycerol in Juglans mandshurica Maxim. var. sachalinensis (Komatsu) Kitam and Juglans regia L. oils. Significant differences are observed in the fatty acid compositions and regiospecific distribution of triacylglycerol in both oils. In addition, we measured volatile compounds and tocopherol content in two walnut oils. In results of volatile compound analysis, vanillin is specifically detected from J. mandshurica var. sachalinensis oil, and was not detected in J. regia L. oil. Notably, γ-tocopherol content in the J. mandshurica var. sachalinensis oil was significantly higher than J. regia L. oil.
