Method for extracting active ingredients from Camellia chrysantha leaves

Abstract

The invention relates to an extraction method for tea leaves, in particular to a method for extracting active ingredients from Camellia chrysantha leaves. The method comprises the following steps: the Camellia chrysantha leaves are collected and washed with clear water; the Camellia chrysantha leaves are cut into small leaf strips by a herbal medicine slicing machine, the small leaf strips are mashed by a mashing machine, and Camellia chrysantha pulp is obtained; the Camellia chrysantha pulp is transferred into a multifunctional stainless steel extraction tank, and pectinase is added to the stainless steel extraction tank; heating sterilization is performed; ethyl alcohol is added, an ultrasonic extraction unit is started for oscillating extraction, filtering is performed after extraction, and residues and a primary filtrate are obtained; water and ethyl alcohol are added to the residues, the mixture is subjected to secondary ultrasonic oscillating extraction, filtering is performed, and a secondary filtrate is obtained; the filtrates are filtered by a 200-mesh plate and frame filter; the primary filtrate and the secondary filtrate are concentrated by a vacuum drier, and a concentrated Camellia chrysantha solution containing the active ingredients is obtained. The extraction method cannot damage biological activity and adopts simple process and normal-temperature concentration, so that loss of physiologically active ingredients is reduced, energy consumption is reduced, and extraction rate is high.

Description

technical field [0001] The invention relates to an extraction method of tea leaves, in particular to an extraction method of active components of golden camellia tea leaves. Background technique [0002] Golden camellia contains tea polyphenols, tea saponins, flavonoids and other physiologically active ingredients, and also contains more trace elements such as organic germanium, selenium and zinc. The water extract of golden camellia tea has the functions of lowering blood sugar, blood fat and serum Cholesterol, inhibit tumor growth, improve body immunity and other physiological functions, and tea polyphenols and tea saponins have been identified as the main functional factors of golden camellia health care products. [0003] At present, the processing and utilization of camellia camellia is mainly to extract its medicinal and health-care components, and then process it into camellia camellia oral liquid, concentrated drinking liquid, tea beverage and tea in bags. Due to th...

Problems solved by technology

Due to the thick waxy layer on the surface of Camellia japonica, the tight structure of the cell wall, thicker veins, and relatively brittle tissue, it has been generally used for a long time to prepare the air-dried leaves of Camellia japonica, and then use the high-temperature and long-time boiling process of traditional Chinese medicine. , there are many disadvantages in the production process, such as many procedures, long cycle, large loss of active ingredients, low extraction rate, etc.
