| Abstract: | The optimal process of extracting total flavonoids from jasminum nudiflorum lindl was studied by single factor test and orthogonal test.The optimum conditions for extracting the total flavonoids assisted by ultrasonic wave are as follow:material-liquid ratio 1:40,ultrasonic temperature 20℃ and ultrasonic time 20min.The optimazed method is stable and efficient,the rate of total flavonoids extracted is up to 18.22%.The RSD in a duplicate test is 1.48%(n=5). |
