The present invention relates to M 3'O cortexmori D beta glucoside and its preparation method and application, which can effectively solve the problem of extracting cortexmori M 3' O D beta Glucoside from mulberry bark, and application problems of HPAEC damage in preparing medicine for treating LPS induced by the method yes, Sangbaipi decoction, decompression concentrating the extracted liquid to obtain dry, dry distilled water suspension, resin column, followed by water, ethanol elution, each gradient eluent was concentrated to dryness, dry matter dissolved in methanol, adding silica gel, added to the liquid chromatographic column with gradient elution, containing the target component flow, vacuum concentration, total A1, A2, A3; total A3 sample was dissolved with methanol on Toyopearl HW 40 column, eluted with methanol, TLC identification, and contain the same flow, got the portion of A3 1, decompressing and concentrating and drying, The ODS column is dissolved by methanol, eluted with methanol, examined by thin layer and combined with the same stream fraction to decompress and condense. The inventive method is novel and unique, easy to operate and use, and has opened up new uses of mulberry bark.
