The Antiradicalic Activity of the Steroidal Glycosides Isolated from Asparagus Officinalis L. This work describes the results of the research in vitro of antiradical/antioxidant properties of the extractive preparation of steroidal (spirostanolic and furostanolic) glycosides (saponins) isolated from the rootstocks and roots of sparrowgrass (Asparagus officinalis L.). Tests using the potentiometrical titration method show the capacity of these substances to absorb peroxide radicals in reactive mixture generating
peroxide radicals. Antiradical activity of individual furostanolic glycoside Asparagoside H represents the linear dependence of the concentration
between 2,5 – 5,8 mg/ml when the maximal radical absorbtion is reached (68.49%). At the same time the index IC50 of Asparagoside H is 4.30
mg/ml. But the same indices for the saponins preparation are about five time less: the maximal absorption (90.62%) of radicals is obtained in a
concerntration of 1.1mg/ml and when the index IC50 is 0.78mg/ml.
