Abstract

Objective: To investigate the constituents of the roots in Osmanthus fragrans.

Methods: The Osmanthus fragrans roots alcohol extract solution were separated and purified by silica gel,Sephadex LH-20 and other materials, the structures were identified by physicochemical properties and spectral analysis.

Results: Thirteen flavonoids were isolated from the roots of Osmanthus fragrans,which identified as glabrol ( 1), dihydroquercetin( 2),2’-hydroxy-5,7,8-trimethoxyflavone( 3),lupinifolin( 4), phloretin( 5), apigenin ( 6), calycosine( 7), quercetin( 8),3’,4’,5,7-tetrahydroxy flavanone( 9),5-hydroxy-7,8,2’,6’-tetramethoxyflavone( 10),isoliquiritigenin( 11),tonkinensisol( 12),kaempferol ( 13).

Conclusion: Compounds 1 ~ 5,7,9 ~ 12 are isolated from the Osmanthus fragrans for the first time.
