In this paper the extracting method and production of Sedum sarmentosum Bunge flavonoid in orthogonal test L_9(3~4)were studied.The results showed that the extracting condition of good yield of flavonoid was 50% C_2H_5OH solution at 60 ℃ for 1h with the solid-liquid ratio 1∶10(g/ml)and the productivevity was 1.265 2%.
