Embodiment Construction

[0026] Below in conjunction with embodiment, the present invention is described further. The following description is by way of example, but the protection scope of the present invention is not limited thereto.

[0027] The method for extracting tea polyphenols with mixed solvent of the present invention, its preparation process is as follows:

[0028] A. Material preparation: select tea leaves that are fresh, tender, color-free, and pest-free, and set aside;

[0029] B. Juicing: Pass the spare tea leaves through the juicer at room temperature, add water while squeezing the juice, the amount of water added is 0.6 times the weight of the tea leaves, and collect the juice; then pass the juice through the shaft press at room temperature Squeeze, collect the tea aqueous solution that is squeezed out, set aside;

[0030] C. Coarse powder preparation: Spray-dry the spare tea aqueous solution, control the air inlet temperature at 140°C and the air outlet temperature at 75°C to obta...

Abstract

The invention discloses a method for extracting tea polyphenol through using a mixed solvent and relates to the technical field of biological medicines. The method comprises the following preparation processes of A, material preparation; B, juicing; C, coarse powder preparation; D, extraction through using the mixed solvent for first time; E, dry powder I preparation; F, extraction through using the mixed solvent for the second time; G, column passing for first time; H, concentration for first time; I, dry powder II preparation; J, extraction through using the mixed solvent for the third time; K, extraction through using the mixed solvent for the fourth time; L, concentration for second time; M, column passing for second time; N, concentration for the third time; and O, drying. The method has the characteristics of simple operation technology, relatively low cost, relatively high extraction rate, relatively high product purity and the like and is suitable for the extraction of the tea polyphenol in tea and also suitable for the extraction of the tea polyphenol in camellia japonica.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a method for extracting tea polyphenols with a mixed solvent. Background technique [0002] Tea Polyphenols (Tea Polyphenols) is the general term for polyphenols in tea, including flavanols, anthocyanins, flavonoids, flavonols and phenolic acids, and is one of the main components that form the color and aroma of tea. It is also an important ingredient with health care functions in tea. Since the 1950s, with the deepening of research and the continuous discovery of the efficacy of tea polyphenols, the functional products of tea polyphenols have increasingly entered the scope of people's lives. Tea polyphenols are not only a natural non-toxic antioxidant, but also A natural and healthy product, it has the functions of preventing liver and coronary atherosclerosis, lowering blood sugar and blood lipids, preventing and fighting cancer, and improving the body's comprehensive immu...
