Abstract:Objective:To optimize the extraction process for astranoside A in Cortex Phellodendri.Methods:To determine the content of astranoside A in extract solution by orthogonal design. Results:The optimum extracting condition was D3A2B3C2, that is, adding eight times amount of 70% alcohol and refluxing and extracting for 90 min (totally extracting for 3 times).Conclusion:The optimized process is stable and highly efficient.
Key words:Cortex Phellodendri;Astranoside A;Extract technology
