Publication date: December 2019Source: Biochemical Systematics and Ecology, Volume 87Author(s): Yan Zhao, Wei Zhou, Shengbao Diao, Zhe Jiang, Mei Jin, Gao LiAbstractPhytochemical research of the roots of Juglans mandshurica Maxim. (Juglandaceae) verified 37 secondary metabolites, including thirteen diarylheptanoids (1–13), five naphthoquinones (14–18), five tetralones (19–23), three lignans (24–26), three phenols (27–29), two anthraquinones (30–31), two triterpenoids (32–33), two secoiridoids (34–35), one naphthalenyl glycoside (36), and one flavonoid (37). The chemical structures of these constituents were elucidated by NMR spectroscopy and compared with data from the literature. This is the first confirmation of the presence of ten compounds (6, 12, 16, 18, 24–26, 30, 32–33) isolated from the family Juglandaceae, two compounds (1 and 8) from the genus Juglans, and four compounds (27, 31, 34–35) from J. mandshurica. The isolation and chemotaxonomic significance of the metabolites from the roots of J. mandshurica were described in this study.Graphical abstract
