Chemical Constituents from Lycii Cortex

OBJECTIVE To study the chemical constituents from Lycii Cortex. METHODS The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis. RESULTS Eight compounds were isolated and their structures were identified as saikolignanoside A (1), scopolin (2), ferulic acid (3), 4-hydroxy-benzoic acid (4), 3-hydroxy- 1-(4-hydroxy-3-methoxyphenyl)propan-1-one (5), trans-N-caffeoyltyramine (6), trans-N-feruloyltyramine (7), dihydro-N- caffeoyltyramine (8), respectively. CONCLUSION Compounds 1, 5 and 7 were isolated from the genus Lycium for the first time.
