Embodiment 1

[0034] 1. Preparation method: Spray 0.5% p-hydroxyphenylethanol aqueous solution on the leaves of growing tea trees, pick the leaves on the second day after spraying, and process them into green tea according to conventional methods to obtain green tea containing salidroside;

[0035] A control group is set at the same time, the difference between the control group and the present embodiment is only that p-hydroxyphenethyl alcohol is not contained in the solvent sprayed to the blades.

[0036] 2, the detection of salidroside: adopt the method of high performance liquid chromatography, get respectively 5g embodiment and the green tea that control group gains, as two groups of samples to be tested, add 25ml of 50% methanol, weigh, heat and reflux for 30 minutes, put Cold, make up the lost weight, filter, as the test solution. Take another salidroside standard substance, add 50% methanol to make a solution containing 0.05mg per 1ml, and use it as the standard solution. Octadecyl...

Embodiment 2

[0039] 1. Preparation method: Spray 10% p-hydroxyphenylethanol aqueous solution on the leaves of the growing tea tree, pick the leaves on the 15th day, and process them into green tea according to the conventional method to obtain green tea containing salidroside;

[0040] A control group is set at the same time, the difference between the control group and the present embodiment is only that p-hydroxyphenethyl alcohol is not contained in the solvent sprayed to the blades.

[0041] 2. Detection of salidroside: the detection method is the same as in Example 1.

[0042] It can be seen from the test results that the content of salidroside in the green tea obtained in this example is 0.014%, and no salidroside can be detected in the control group.

Embodiment 3

[0044] 1. Preparation method: Spray 5% p-hydroxyphenylethanol aqueous solution on the leaves of growing tea trees, pick the leaves on the 7th day, process them into green tea according to conventional methods, and obtain green tea containing salidroside;

[0045] A control group is set at the same time, the difference between the control group and the present embodiment is only that p-hydroxyphenethyl alcohol is not contained in the solvent sprayed to the blades.

[0046] 2. Detection of salidroside: the detection method is the same as in Example 1.

[0047] It can be seen from the test results that the content of salidroside in the green tea obtained in this example is 0.035%, and no salidroside can be detected in the control group.

Abstract

The invention provides a preparation method of tea containing salidroside. The method comprises the following steps: spraying p-hydroxyphenylethyl alcohol to growing camellia sinensis leaves, and picking to obtain the tea containing salidroside. The method provided by the invention is simple in step; a synthetic precursor, namely p-hydroxyphenylethyl alcohol, of the salidroside is directly supplied from the external world; and uridine diphosphate glucose and glucosyltransferase contained in the tea are taken as raw materials, and the salidroside is synthesized in a tea body. The prepared tea containing the salidroside and application of the tea are further protected in the invention.

Description

technical field [0001] The invention relates to the technical field of biotransformation, in particular to a method for preparing tea leaves containing salidroside. Background technique [0002] Salidroside (salidroside) is the most important medicinal ingredient of Crassulaceae (Crassulaceae) Rhodiola (Rhodiola L.) plant, which has anti-fatigue, enhanced immunity, cardiovascular protection, anti-hypoxia, anti-aging, Protect nerve cells, protect the liver, anti-oxidation, anti-tumor, anti-radiation and other specific effects. It has extremely important application value in military, aerospace, sports and health care medicine. In recent years, there are more and more types of products such as pharmaceuticals, beverages, food and cosmetics produced with it as the main raw material, and people's demand for salidroside is increasing. [0003] Rhodiola plants are the main source of extracting salidroside, but wild resources are scarce, and the content of salidroside is very low...
