Abstract: Flavonoids from Apoacynum venetum leaves were prepared according to a L9(34) orthogonal test plan. The relationship between extracting conditions and yield of flavonoids extracted from Apoacynum venetum leaves was investigated. Experiment results showed that using 50% alcohol as extracting solvents, at 40℃, 1h and 1:30.

Key words: Apoacynum venetum leaves, flavonoid, extract
