Abstract: Ethanol immersion extraction was used to extract flavonoid compounds of the Datura Stramonium L. The results showed that the optimum condition of extraction is 60℃and 95% ethanol 70ml, extract time 1h . The total flavonoids contents are assayed by using spectroscopic methods with rutin as standard. The flavonoids content is 4.016% at the optimum condition.The method is simple, repid,reproducible and suitable for the determination of total flavonoids in Datura Stramonium L.

Key words: Datura Stramonium L., total flavones, spectroscopic methods, extraction process
