Abstract:Objective: To study the chemical constituents of an active fraction (DSS-A-N-30) from Danggui Shaoyao San. Method: DSS-A-N-30 was prepared by macroporous resin chromatography, the compound was isolated by column chromatography on silica gel and RP C-18, the structure was elucidated by spectroscopic methods. Result: A new monoterpene glycoside was isolated and identified from DSS-A-N-30. Conclusion: The new monoterpene glycoside was identified as 4″-hydroxyl-albiflorin.
