| Abstract: | Objective] To establish and optimize the method of extracting total flavonoids from Liriope spicata(Thunb.) Lour.var.prolifera Y.T.Ma tuberous roots.Method] The affecting factors such as immersing time,solid to liquid ratio,ethanol volume fraction and ultrasonic power were studied by the way of single factor and orthogonal tests analysis,with the methods of ultrasonic auxiliary.Result] The ultrasonic power was the main influencing factors.The optimal conditions of extraction were showed as follows: immer... |
