摘要：

Five new alpha-tetralonyl glucosides, juglanosides A-E (1-5) were isolated from the fresh rejuvenated fruit of Juglans mandshurica. Their structures were elucidated as (4S)-4-hydroxy-alpha-tetralone 4-O-beta-D-glucopyranoside (1), (4S)-4,5-dihydroxy-alpha-tetralone 4-O-beta-D-glueopyranoside (2), (4S)-4,6-dihydroxy-alpha-tetralone 4-O-beta-D-glucopyranoside (3), (4S)-4,5,8-trihydroxy-alpha-tetralone 4-O-beta-D-glucopyranoside (4), and (4S)-4,5,8-trihydroxy-alpha- tetralone 5-O-beta-D-glueopyranoside (5) on the basis of spectroscopic analysis and chemical evidence.
