Objective: To study the chemical constituents of Saussurea involucrata.
Method: Compounds were isolated and purified by column chromatography, and their structures were elucidated by chemical and spectroscopic methods.
Result: Eight compounds were yielded and identified as beta-sitosterol (1), dotriacontanoic acid (2), hexacosan-4-olide (3), (+)-11alpha, 13-dihydrodehydrocostuslactone (4), 8alpha-acetoxydehydrocostus lactone (5), zaluzanin C (6), 11,13beta-dihydrozaluzanin C (7), 8alpha-hydroxy-11beta-11,13-dihydrodehydrocostuslactone (8).
Conclusion: Compounds 2-7 were first isolated from S. involucrate.
