| Abstract: | Chemical investigation of the pericarps of Juglans regia led to the isolation of sixteen compounds, including five α-tetralone (1-5), five phenolic acids (6-10), two phenylpropanoids (11, 12), one diarylheptanoid (13), one sesquiterpene (14), and two α- tetralone dimers (15, 16). Among them, compounds 2, 4, 5, 11, 12 and 13 were isolated from J. regia for the first time, and compounds 10 and 14 were reported for the first time from Juglandaceae. The chemotaxonomic significance of these compounds was summarized. |
