C.Z. : 615.31 This paper presents the results of the study concerning
the Rutozide extraction from Sophora Japonica buds.The correlation bet
ween the extraction process performance and the factors influencing th
e process, i.e. temperature, duration and float ratio (alcohol mass /
plant mass), was aimed at. A regression equation, describing the depen
dence between the process field and the above mentioned variables, was
worked out and then the equal level curves, characteristic to the ext
raction performance for various variables values, were drawn.
