Objective:
To study the structures of secondary saikosaponins in saiko decoction.
Method:
The structures of saikosaponins were separated from saiko decoction and identified by various separation and spectral techniques. HPLC method was adopted for identifying all of separated saikosaponins.
Result:
Eleven saikosaponins were separated from saiko decoction. Four of the seven new constitutes contained in saiko decoction were identified.
Conclusion:
This study lays a foundation for improving the identification of secondary saikosaponins.
