Study on Chemical Constituents from the Root of Hemerocallis citrina
Objective; To study the chemical constituents root of Hemerocallis citrina. Methods; The chemical constituents were extracted by microwave method and purified by silica gel column. Their structures were elucidated by their physical and chemical properties and spectral methods. Results; 7 compounds were isolated and identified as; chrysophanol( I ), 2-methoxy-obtusifolin( H ) ,ob-tusifolin( DI) ,rhein( IV) ,aloe-emodin( V) ,hemerocallone( VI) and hemerocallin( VE). Conclusion; Compounds Ivand VI are isolated from this plant for the first time.
