Abstract :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 insert ignore into journalissuearticles values(1-2);, one new taraxasterol oleate insert ignore into journalissuearticles values(3);, and six known triterpenoids taraxasterol insert ignore into journalissuearticles values(4);, taraxasterol acetate insert ignore into journalissuearticles values(5);, ptiloepoxide insert ignore into journalissuearticles values(6);, lupeol insert ignore into journalissuearticles values(7);, lupeol acetate insert ignore into journalissuearticles values(8);, and beta-sitosterol insert ignore into journalissuearticles values(9); were characterized. The structures of the isolated compounds were elucidated on the basis of NMR insert ignore into journalissuearticles values(H-1, C-13, COSY, HMBC, HSQC, and TOCSY);, UV, FT-IR and LC-Q-TOF-MS spectrometric data.
