Problems solved by technology
The invention discloses an anthricin preparation method. The method includes the following steps: 1), taking anthricin for smashing, adding 5-10 times of amount of 30-90% ethanol solution, performing reflux extraction for 2-3 times, concentrating an extracting solution to be alcohol-free, adding the extraction solution in macroporous resin for adsorption, using ethanol solution for gradient elution, collecting eluent, depressurizing for concentration, adding benzene solution in size volume and fully stirring, collecting a benzene solution layer to be concentrated to a small size, and placing for crystallization; 2), dissolving obtained crystals by 5-10 times of amount of 80-90% methanol, adding activated carbon for decoloring, concentrating filtrate to enable alcohol concentration to be 30-50%, extracting by benzene solution, adding 1/3-1/10 ethanol solution in extract liquor, placing for recrystallizing, and drying crystal substances to obtain anthricin. The anthricin preparation method is simple and convenient in process operation, low in production cost and easy to realize industrial production.
