Abstract: The extraction conditions are confirmed through the extraction of leaf of Nerium indicum Mill. The optimal conditons are: the liquor of extraction is the sparse sulfuric acid(0.025 mol/L), the time of extraction is 5h, the temperature of extraction is 40℃. According to the experimental conditions above, the content of alkaloid in bark is maximum, the content of alkaloid in turn is:bark>leaf>stalk.

Key words: Nerium indicum Mill, alkaloid, extraction
