Objective:
To find out the optimum extraction technology of soyasaponins from residual of bean ware.
Methods:
The optimum extraction conditions were investigated by the orthogonal design, and the content of soyasaponins was determined by UV-spectro-pho-tometry.
Results:
The optimum extraction technology was A3B1C1, that is adding 7 times and 6 times amount of 70% alcohol and refluxing for two times and each time for 1.0 h.
Conclusion:
The selected technology showed higher yield of soyasaponins, good stability and high efficient.
