Abstract:

The natural structure of saponins may not stay in the best active state. To enlarge its application and gain intensive
insight into the relationship between structure and function, modification of sugar chains in soyasaponins is required.
Derivatives of soyasaponin Ab were prepared by adding either dodecylamine or phenylethylamine in the presence of carbodiimide.
The semi-synthesized derivatives of soyasaponin Ab with weak polarity were identified by IR, EMI-MS, and
NMR. The derivatives can be used for further exploration of the relationship between immunostimulating adjuvant/haemolytic
activities and molecular structure of soyasaponins and their derivatives.

Key words: soyasaponin Ab, dodecylamine, phenylethylamine, derivatives
