Objective:
To study the chemical constituents of Artemisia ordosica.
Method:
The chemical constituents were isolated and repeatedly purified on silica gel column and the structures were elucidated by the NMR spectra and physico-chemical properties.
Result:
Eight flavonoids were obtained and identified as 5-hydroxy-7, 4'-dimethoxyflavanone, 5-hydroxy-7, 4'-dimethoxyflavone, 5, 4'-dihydroxy-7-methoxyflavone, 5, 7-dihydroxy-6, 4'-dimethoxyflavone, 5, 4'-dihydroxy-7-methoxyflavanone, 5, 3', 4'-trihydroxy-7-methoxyflavanone, 5, 7-dihydroxy-3', 4'-dimethoxyflavone and 5, 3', 4'-trihydroxy-7-methoxyflavone.
Conclusion:
All the compounds were obtained from A. ordosica for the first time.
