Studies on chemical constituents of Tephroseris phaeantha
Chemical constituents of Tephroseris phaeantha were isolated by column chromatography and semi-prepared HPLC,the structures were elucidated of spectral data and physical-chemical properties.Five compounds were isolated and respectively identified as tetracosanoic acid(1),daturic acid 2,3-dihydroxypropyl ester(2),α-palm acid monoglyceride(3),β-sitosterol-glucopyranoside(4),Oleanolic acid(5).Compound 1~5 are isolated from Tephroseris phaeantha for the first time.
