Friedelin and epifriedelinol were isolated and identified from the dried root of Aster tataricus. Shionone, m.p. 158.5-159.5°, isolated and named by Nakaoki in 1932, was also obtained. It was assumed that this substance is a four-ringed triterpenoid, C₃₀H₅₀O, possessing one carbonyl. Besides these, a substance assumed to be astersaponin, isolated and named by Nakaoki in 1929, was also obtained.
