Embodiment 1

[0063] Embodiment 1: Preparation of total phenolic acids of Kudingcha Dongqing

[0064] Take 1 kg of holly leaves of Kudingcha, grind them into coarse powder, add 95% alcohol to reflux and extract for 3 times, combine the extracts, concentrate under reduced pressure, and obtain 280 g of alcoholic extract. Stir and dissolve the extract with 1.5L purified water, add dilute sodium hydroxide dropwise to adjust the pH value to about 7, centrifuge, filter, acidify the filtrate to pH 2 with 5% hydrochloric acid, let stand for 2 hours, filter, wash the precipitate with water until the effluent The pH was about 5, and it was drained to obtain about 128g of precipitate. Add the filtrate to a polyamide (30-60 mesh) adsorption column, and elute with water first. When the color of the effluent becomes lighter and the acidity drops to about pH 5, use 80% alcohol for eluting, and collect the alcohol eluate. Concentrate under reduced pressure to obtain about 12 g of paste, which is incorpora...

Embodiment 2

[0065] Take 1 kg of holly leaves of Kudingcha, crush them into coarse powder, add water to decoct 3 times, combine the extracts, concentrate under reduced pressure to obtain 220 g of extract. Stir and dissolve the extract with 1.5L water, add 5% sodium carbonate to adjust the pH to about 7, centrifuge, filter, acidify the filtrate to pH 2 with 5% sulfuric acid, let it stand for 2 hours, filter, wash the precipitate with water until the effluent pH is about 5, Dried up, about 100 g of precipitate was obtained. Add the filtrate to a polyamide (30-60 mesh) adsorption column, elute with water first, until the color of the effluent becomes lighter and the acidity drops to about pH5, use 60% alcohol for eluting, collect the alcohol eluate, reduce Concentrate under reduced pressure to obtain about 10 g of a paste, which is incorporated into the precipitated part. After the precipitate was dried, reflux with hexane to degrease 3 times, filter, evaporate to dryness, and then reflux wi...

Embodiment 3

[0066] Example 3: Preparation of Kudingcha Dongqing Total Phenolic Acid

[0067] Get the total phenolic acid 20g that embodiment 1 or 2 gained, slowly add 5% sodium hydroxide appropriate amount in batches, make fully dissolving under stirring, control solution pH7~8, filter, spray dry, obtain total phenolic acid salt 19g. This product has good water solubility and can be used as a raw material for various solid and liquid preparations.
