Anti-stress and puffed mixed feed for ctenopharyngodon idellus and production method for feed

The invention relates to anti-stress and puffed mixed feed for ctenopharyngodon idellus and a production method for the feed. The mixed feed includes the following raw materials in mass percentage: 0-8% of meat and bone meal, 2-5% of broad bean albumen powder, 8-18% of soybean meal, 20-30% of rapeseed dregs, 10-15% of cottonseed meal, 10-20% of wheat, 10-20% of tapioca flour, 5-8% of rice bran, 2-4% of soya-bean oil, 0.2-0.4% of 50% choline chloride, 0.9-1.5% of monocalcium phosphate, 1-2% of vitamin premix, 1-2% of mineral premix, 1-2% of zeolite powder, 0.02-0.1% of GSH, 0.01-0.08% curcumin, 0.01-0.03% of tea polyphenol, 0.05-0.1% of taurine, 0.005-0.01% of rheum emodin, 0.01-0.02% of L-carnitine, and 0.02-0.03% of complex enzyme preparation. The anti-stress and puffed mixed feed improves the digestibility and deposition of feeding ctenopharyngodon idellus to nutrient substances of the feed, improves the immune, antioxidant and anti-stress ability of fish body and promotes growing of ctenopharyngodon idellus.

The invention relates to a combined extraction and purification technique for multiple active ingredients of a medicinal plant, in particular to a combined extraction and purification technique for multiple active ingredients of polygonum multiflorum. According to the method, stilbene glucoside, rheum emodin and chrysophanol in the polygonum multiflorum can be maximum extracted from the polygonum multiflorum into a solvent by using 70-80 percent of ethanol as an extraction solvent and are separated from starch in residual slag; water-soluble differences of the stilbene glucoside, the rheum emodin and the chrysophanol are used and water is used as a solvent so that the stilbene glucoside in alcohol extracts can be separated from the rheum emodin and the chrysophanol, and a crude product is obtained; the rheum emodin and the chrysophanol can be respectively separated from the alcohol extracts by successively using 5 percent of sodium carbonate and 5 percent of sodium hydroxide as solvents, and the rheum emodin and chrysophanol crude product can be obtained through an acid precipitation; and the polygonum multiflorum ethanol extract residual slag is washed by using water, and the starch with a purity of 85-87 percent can be obtained through precipitating water washing liquid. The invention has the characteristics of low cost, high efficiency, no pollution and high product purity.

The invention relates to a chemical modification method capable of improving the anti-cancer activity of reactive oxygen species (ROS) through improving the producing ability of the ROS of rheum emodin. Experiments prove that a series of rheum emodin hyamines obtained by chemical modification to the rheum emodin have better anti-cancer activity on three kinds of cancer cells such as skin cancer A375, liver cancer HepG2 and stomach cancer AGS, and the anti-cancer activity and the producing ability of the ROS far exceeds those of the rheum emodin; moreover, experiments prove that the producing ability of the ROS and the anti-cancer activity of rheum emodin derivates are in positive correlation. The drug chemically modified by the chemical modification method has a certain selective killing effect on the cancer cells, and has a better prospect for development as an anti-cancer drug.
