Four sterol compounds were isolated from the roots of Ligularia dentata. On the basis of spectroscopic methods(such as:IR, EIMS,1HNMR,13CNMR, DEPT), they were identified as ergost6,22dien3β, 5α 8αtriol(1), stimast5en3βol7one(2),stigmast4en6βol3one(3),stigmast4en6αol3one(4), respectively. Compound 1 was reported for the first time in natural products.
