Crude product is carried out in sodium potassium tartrate tetrahydrate, potassium dihydrogen phosphate, ferrous sulfate tea polyphenols acidifying solution is obtained by extraction.
Based on the above technical solution, the present invention can also be improved as follows
Further, described that tea waste be crushed into 200~300 mesh sieve, and reflux extraction in ethanol, by extracting solution
Filtering, the technical essential for obtaining purification solution are as follows：
Tea waste is pulverized and sieved, and under the conditions of 60~70 DEG C, 0.5~1h of reflux extraction in 45~50% ethyl alcohol,
Extracting solution is filtered, purification solution is obtained.
Further, described in purifying solution, zinc chloride, sodium carbonate precipitation are added according to a certain percentage, precipitation is filtered,
The technical essential for obtaining finished product is as follows：
In purifying solution, the zinc chloride of 3.21~4.53g, the sodium carbonate precipitation of 2.53~3.56g is added, will precipitate
Filter, obtains finished product.
Further, described to be dried in vacuo finished product, sterling is obtained, sterling is evaporated under reduced pressure to obtain the technical essential of crude product such as
Under：
Using electric heating constant-temperature blowing drying box, recirculated water multiplex vavuum pump, by finished product under the conditions of 80~100 DEG C, vacuum
Dry, 3~5h obtains sterling, and sterling is evaporated under reduced pressure to obtain crude product.
Further, described to carry out in sodium potassium tartrate tetrahydrate, potassium dihydrogen phosphate, ferrous sulfate crude product tea polyphenols are obtained by extraction
The technical essential of acidifying solution is as follows：
By crude product in the sodium potassium tartrate tetrahydrate of 1.21~2.53g, the potassium dihydrogen phosphate of 5.11~6.22g, 1.71~2.33g
It carries out that tea polyphenols acidifying solution is obtained by extraction in ferrous sulfate.
The beneficial effects of the invention are as follows：Method is simple, at low cost, easily realizes, and extraction rate is fast, purity is high.
