Objective To study the chemical constituents of flavonoids from Scutellaria barbata. Methods A review on the silica gel columm and Sephadex LH-20 were summarized based on the spectral data. Results Twelve flavonoids were isolated from Scutellaria Barbata, eriodictyol, scutellarein, salvigenin, baicalin, apigenin, wogonin, 4'-hydroxywogonin, luteolin, 4',5-dihydroxy-3',5',6,7-tetramethoxyflavone, naringenin, 7-hydroxy-2',5,8-trimethoxyflavanone, cosmosiin, respectively. Conclusions All compounds are flavonoids, including flavonoid aglycones and glycosides. It may provide scientific basis for the analysis of flavonoids from Scutellaria barbata. |
