[Study on extraction technology of soyasaponins from residual of bean ware].
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.


CONCLUSIONS
The selected technology showed higher yield of soyasaponins, good stability and high efficient.
