The application relates to the technical field of kidney treatment, and particularly discloses a method for extracting emodin and application of the emodin in renal ischemia-reperfusion injury. The method comprises the following steps: S1, crushing traditional Chinese medicine rhubarb raw materials to obtain traditional Chinese medicine rhubarb powder; S2, mixing the traditional Chinese medicine rhubarb powder with ethanol and performing ultrasonic treatment to obtain a primary extraction solution; S3, adding cellulase to the primary extraction solution to obtain an enzymatic solution; S4, performing supercritical CO2 extraction on the enzymatic solution, and collecting an extraction phase; S5, adding ethyl acetate to the extraction phase for extraction, and then separating an organic phase; S6, crystallizing the organic phase, and filtering to obtain emodin crude products; and S7, recrystallizing the emodin crude products with methanol, and drying to obtain finished products. The method for extracting emodin can be used for preparing medicines for treating kidney diseases, in particular, renal ischemia-reperfusion injury, and has the advantages of high extraction efficiency, high product purity and a green and environment-friendly process.

The application relates to the technical field of montmorillonite, in particular to modified montmorillonite for improving animal intestinal tracts and a preparation method thereof, which comprises the following steps: stirring and mixing montmorillonite, citric acid and water, and extruding to obtain extruded montmorillonite; adding calcium oxide, magnesium carbonate and water into the extruded montmorillonite, filtering after high-temperature and high-pressure reaction to obtain intercalated montmorillonite; high-speed stirring the intercalated montmorillonite and / or multi-element montmorillonite, astragalus root powder, coptis root powder, rhubarb powder and scute powder, screening after standing to obtain composite particles; drying, grinding and screening the composite particles to obtain modified montmorillonite. The prepared modified montmorillonite can improve intestinal tract functions and has obvious antidiarrheal effect, especially has good functions on intestinal tract diarrhea caused by hard feed, and can increase body weight.
