| titleOfInvention | Method for preparing oxymatrine from subprostrate sophora |
| abstract | The invention provides a method for preparing oxymatrine from vietnamese sophora root, which comprises the steps of crushing vietnamese sophora root, adding a bacillus subtilis liquid chamber for warm fermentation, adding ethanol for high-temperature extraction, and filtering to obtain filtrate I and filter residue I; adding the filter residue I into an ethanol solution for high-temperature extraction, and filtering to obtain a filtrate II; mixing the filtrate I and the filtrate II, concentrating under reduced pressure, and extracting with ethyl acetate to obtain water phase; adjusting the pH value of the water phase to 7.5-8, and extracting with ethyl acetate to obtain an ethyl acetate phase; concentrating the ethyl acetate phase, loading on a silica gel column, and eluting with an ethanol solution to obtain an eluent I; and concentrating the eluent I, crystallizing overnight at 4-8 ℃, and filtering to obtain the oxymatrine product. |
