Objective:
To study the chemical constituents of Rhizome of Buddleia davidii.
Methods:
The chemical constituents were isolated by repeated column chromatography (Toyopearl HW-40C and HPLC) and their structures were elucidated on the basis of physico-chemical properties and spectroscopic features.
Results:
From the petroleum ether extract of the material, eight compounds were isolated. Their structures were identified as: Buddlindeterpene B(1), Buddledin B(2), Buddledin C(3), deacetyldihydrobuddledin A(4), dihydrobuddledin C(5), Suberosol B(6), Gadain (7) and Hinokinin (8).
Conclusion:
Compounds 1,4 - 8 are isolated from B. davidii for the first time.
