Objective: To study the chemical constituents of an active fraction (DSS-A-N-30) from Danggui Shaoyao San.
Method: DSS-A-N30 was prepared by macroporous resin chromatography, the compound was isolated by column chromatography on silica gel and RPC-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.
