Fractions of triterpenoids have been isolated from herb, inflorescences, and rhizomes with roots of Hieracium pilosella by typical extraction with petroleum ether. The fraction from inflorescences was investigated using GC‐MS techniques. The occurrence of α‐ and β‐amyrin, taraxerol, taraxasterol, and fern‐7en‐3β‐ol has been observed. Quantitative analysis was also performed and taraxasterol is distinctly predominant in this triterpenoid fraction. Thin‐layer chromatography on silica gel was performed on all the investigated fractions and additionally revealed the occurrence of lupeol and ψ‐taraxasterol in vestigial quantities. All of the triterpenoid components are reported for the first time in the investigated plant.
