Pennogen's sequential steroid saponin has been obtained by us from the Polygonatum glaberrimum C. Koch plant, which has a widespread and toxic effect on our republic and has a chemical structure. Many steroid saponins, especially glycosides with dioxine, have been widely studied in chemical-toxicological aspects, but pneumonia-containing saponins have not been investigated in this regard. Taking this into consideration, we needed to investigate this glycoside chemical-toxicological aspect.
