Chromatographic separation of n -hexane and ethyl acetate fraction of a crude methanol extract obtained from aerial parts of the Scorzonera aucheriana DC collected from Sivas province of Turkey yielded nine natural compounds; two new 3-caffeoyl-quinic acid analogs ( 1 - 2 ), one new taraxasterol oleate ( 3 ), and six known triterpenoids taraxasterol ( 4 ), taraxasterol acetate ( 5 ), ptiloepoxide ( 6 ), lupeol ( 7 ), lupeol acetate ( 8 ), and β -sitosterol ( 9 ) were characterized. The structures of the isolated compounds were elucidated on the basis of NMR ( 1 H, 13 C, COSY, HMBC, HSQC, and TOCSY), UV, FT-IR and LC-Q-TOF-MS spectrometric data.
