| Abstract: | The extracting condition on flavonoids from Rhododendron molle was optimized by orthogonal test design methods and UV--spectrophotometry was used for the determination of flavonoids. Effects of ethanol contents, extraction time, extraction times and ratio of liquid to material on flavonoids contents were investigated. The optimum extracting conditions were 70% alcohol as solvent, ratio of liquid to material 25：1, extracting times 2, each extracting time 30min. |
