[0017] 1. Extraction and purification method of dog liver vegetable polysaccharide
[0018] Weigh 2000g of dry whole grass powder of dog liver dish, add 20000ML petroleum ether to reflux for degreasing and extract for 2 hours, after the medicinal dregs evaporate the petroleum ether, extract with boiling water twice, each time for 1.5 hours, combine the extracts, concentrate to 200 mL, mix with chloroform and The ratio of n-butanol is 4:1, and the Sevag method is used for multiple extractions to obtain a protein-free supernatant, and 95% ethanol is added to make the alcohol content reach 80%, and alcohol precipitation is carried out in a refrigerator at 4°C for 12 hours. Suction filtration, discard the supernatant, and wash the filter residue successively with ether, absolute ethanol, and acetone to obtain the crude polysaccha...

Abstract
The invention belongs to the field of traditional Chinese medicines, and relates to dicliptera chinensis polysaccharide extracted and purified by using dicliptera chinensis whole herb as a raw material and application of the dicliptera chinensis polysaccharide in preparation of medicines for treating liver injury caused by antituberculosis drugs. The present invention discloses a preparation method of the dicliptera chinensis polysaccharide, and animal experiments prove that the dicliptera chinensis polysaccharide has very good effect on treatment of drug-induced liver injury in mice caused by combined use of antituberculosis drugs isoniazide and rifampicin. The dicliptera chinensis polysaccharide can be applied not only to chemical liver injury, and also has specific effects on tuberculosis drug-induced liver injury; the new application opens up a new area for medicinal value of the dicliptera chinensis polysaccharide, and the dicliptera chinensis polysaccharide has important application value and economic benefit.
