[Determination of total flavonoids and dihydromyricetin in Ampelopsis grossedentala (Hand-Mazz) W. T. Wang].
OBJECTIVE
To establish a method for the assay of total flavonoids and dihydromyricetin in A. grossedentala.


METHODS
The flavonoids were determined by spectrophotometry and dihydromyricetin by TCL-scanner.


RESULTS
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%.


CONCLUSIONS
The method is rapid, simple, accurate and good for the determination of total flavonoids and dihydromyricetin in A. grossedentala.
