- Abstract
β-Sitosterol and the new phytosteroid 24 S-ergost-4-en-3,6-dione were isolated from the industrial extraction waste of the alkaloid-bearing plant Aconitum septentrionale Koelle. The structure of the isolated compound was determined by x-ray structure analysis and PMR, C NMR, and IR spectroscopy. The crystal structure of the steroid contains a disordered terminal 24-methyl,24-isopropyl group that occupies two positions in a 0.55:0.45 ratio.
