Comparison of extraction methods for secologanin and the quantitative analysis of secologanin from Symphoricarpos albus using 1H-NMR.


In order to develop an efficient large-scale extraction of secologanin from Symphoricarpos albus, different methods have been compared. Ultrasonication with organic solvents and water, microwave-assisted extraction and hot water extraction methods were evaluated for their efficiencies. Among the methods tested, ultrasonication with methanol showed the… (More)
