| Abstract: | OBJECTIVE: To establish a method for the assay of total flavonoids and dihydromyricetin in A. grossedentala. METHOD: The flavonoids were determined by spectrophotometry and dihydromyricetin by TCL-scanner. RESULT: The content of flavonoids was 43.4%-44.0%, RSD 1.56%-2.62% and the content of dihydromyricetin was 37.4%-38.5%, RSD 1.85%-2.65%. CONCLUSION: The method is rapid, simple, accurate and good for the determination of total flavonoids and dihydromyricetin in A. grossedentala. |
