Embodiment Construction

[0010] 1. Preparation Example

[0011] Take 500g of stems and leaves of Grape dentatus, add 7L of 70% ethanol after crushing, leaching for 0.5 hours at 80°C, filter while hot, then add 5L of ethanol for leaching for 0.5 hours, combine the filtrates, concentrate the filtrates under reduced pressure, and spray dry to obtain crude Crystal (vine tea flavone) 120g, add 720ml of acetone, reflux extraction for 0.5 hours, suction filtration, acetone reflux extraction for 0.5 hours again, combine the filtrate, concentrate the filtrate under reduced pressure to nearly dryness, add 2000ml of distilled water, stand for 24 hours to crystallize, centrifuge Add 200ml of acetone, reflux and extract for 0.5 hours, filter with suction, concentrate the filtrate to near dryness under reduced pressure, add 2000ml of distilled water and let stand for 24 hours to recrystallize, centrifuge and dry the crystals to obtain dihydromyricetin.

Abstract

An application of dihydromyricetin as the additive of forage for improving the quality of meat is disclosed. Said dihydromyricetin is prepared from the stem and leaf of amur ampelopsis through extracting in alcohol, concentrating, drying to obtain coarse flavone, reflux extracting in acetone, vacuum concentrating, adding water, educing out crystals, and recrystallizing.

Description

field of invention [0001] The invention relates to the field of feed additives, in particular to the field of feed additives for improving the quality of animal products. Background technique [0002] At present, my country's total meat and egg production ranks first in the world, and the per capita annual meat consumption of urban residents has reached 32.94 kg (National Bureau of Statistics, 2004), which is close to the world average level and basically bid farewell to the history of "shortage" economy. While gradually satisfying the demand for the quantity of meat, people have put forward higher and higher requirements for the quality of meat. However, due to the influence of genetics, breeding environment, feeding management and other aspects, the quality of meat products has become prominent, especially in terms of meat processing quality, which is manifested as pale meat, water seepage, and decreased tenderness and flavor of chicken and pork. The poor quality of meat ...
