Cultivation method and application of a plant containing salidroside

Abstract

The invention provides a method for cultivating plants containing salidroside. The method comprises the following steps: spraying p-hydroxyphenylethanol on growing plant leaves, and harvesting to obtain plants containing salidroside. The method provided by the invention has simple steps. The synthetic precursor of salidroside, p-hydroxyphenylethanol, is directly supplied from the outside, and the uridine diphosphate glucose and glucosyltransferase contained in the plant itself are used as raw materials to synthesize the salidroside in the plant. Tianglycoside. The present invention further protects the application of the salidroside-containing plants obtained through cultivation.

Description

technical field [0001] The invention relates to the technical field of biotransformation, in particular to a method for cultivating plants 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, ...

Problems solved by technology

However, the main function of β-glucosidase in organisms is to catalyze the hydrolysis of glycosidic bonds, and the synthesis of salidroside uses its reverse reaction, which is limited by thermodynamic control and reaction balance, and the yield is low

[0007] Salidroside can also be synthesized by chemical method, but because the chemical synthesis process needs to go through multi-step protection and deprotection measures, the process is complex and costly, there are many by-products and difficult to separate, and it is more harmful to the environment, so no major mass production

[0008] In summary, the current synthetic methods of salidroside have not been widely used in industry due to reasons such as high production cost, low yield, and complicated synthetic steps.

Although there are reports in the prior art about adding specific raw materials to the water body or soil where plants grow, and generating salidroside through biotransformation, this addition method requires real-time monitoring and continuous replenishment of substances in the water body or soil, and the operation It is complex, and a large amount of added raw materials is lost, most of which cannot be absorbed, the conversion efficiency is not high, and it has a certain toxic effect on the plant root system, affecting root growth
