| Abstract: | Objective] The study aimed to optimize the procedures for flavonoids ex-traction from of Lophatherum gracile. Method] The powder of L. gracile leaf （3.0 g） was weighed and extracted fol owing an orthogonal design including the solid-liquid ratio, extraction time, extraction times and soaking time at three levels. Result] The optimal parameters were solid-liquid ratio at 1：40, extraction time of 40 s, extraction times of two times and soaking time of 40 min. Conclusion] Smashing tissue ex-traction of flavonoids is rapid and efficient, which provides a new method for the development and utilization of L. gracile. |
