Juglans mandshurica Max., a fast growing hardword species in family of Juglandaceae, has an extensive distribution ranging from China, Siberia to Korean peninsula. The tree has been used as a folk medicinal plant for treatment of esophageal, gastric, cardiac and lung cancer [1–3]. By comparison of mass fragmentation pattern of each component with two modern MS libaries namely Wiely 6 and NIST, the volatile compounds from root shell of J. mandshurica were determined as three naphthoquinone derivatives such as 1,4-naphthoquinone (I), 5-hydroxy-1,4-naphthoquinone (Juglone, II) and 5-hydroxy-2-methyl-1,4-naphthoquinone (plumbagin, III), and one aliphatic alcohol, 3-ethyl-2-methyl-1-pentene-3-ol (IV). Evaluated by quantitative investigation with authentic compounds of the three corresponding naphthoquinone derivatives, compounds I and II were the major volatile components in J. mandshurica root shell and their yields were around 54.4µg/g and 21.3µg/g, respectively.
