Objective: To study the chemical constituents of Oxytropis falcate. Method: The air-dried whole plants of O. falcate were extracted with EtOH (90%) three times at room temperature. The compounds were isolated by silica-gel, pelyamide, C-18 and Sphadex LH -20 columns. The structures were identified based on spectral elucidation. Result: Fourteen compounds were isolated from O. falcate and identified as, ( - ) -7-methoxy-dihydroflavone ( 1 ), ( - ) -5-hydroxy-7-methyoxy-dihydroflavone (2), ( - ) -pino- cembrin (3), (-)-7-hydroxy-dihydroflavone (4), 4'-methoxy-2'-hydroxy-chalcone (5), 2', 4'-dihydroxy-dihydrochalcone (6), 2' ,4'-dihydroxy-chalcone ( 7 ), ( - ) -maackiain ( 8 ), tetrahydroflemichapparin-B ( 9 ), dalbergin ( 10 ), N-benzoyl-2-phenylethyl- amine ( 11 ), n-tetracosanol ( 12 ), rhamnocitrin-3-O-β-neohesperidoside ( 13 ), β-sitosterol ( 14 ). Conclusion: All the compounds were isolated from O. falcate for the first time. |
