[Abstract] Objective: To determine the content of total flavonoids in Kudingcha of Oleaceae from Guizhou Province and its processing products. Methods: The total flavonoid was determined by UV spectrophotometry at 507 nm, with rutin as a reference substance. Results: The content of flavonoids had different scales in Kudingcha of Oleaceae from Guizhou Province and its processing products. The highest contents were 39.71 mg/g and the lowest were 12.11 mg/g. The total flavonoids in tender leaves of processing products were lower than that in old leaves. Conclusion: The method is simple, accurate and reliable, and it can be used for the determination of the total flavonoids in Kudingcha of Oleaceae from Guizhou Province and its processing products.
