Artificial cultivation method for increasing content of active ingredients in roots, stems and blades of red-rooted sage

Abstract

The invention discloses an artificial cultivation method for increasing content of an active ingredient in roots, stems and blades of red-rooted sage. In the method disclosed by the invention, a step of spraying a mixed aqueous solution of methyl salicylate and methyl jasmonate is only added on the basis of the original conventional production and planting process, and the sprayed aqueous solution is prepared by adding 0.01-0.25g of chemically pure or industrially pure methyl salicylate and 0.015-0.40g of methyl jasmonate into 100L of water and then stirring. The method is simple to implement, the investment is less, the harvest is great, the total content of salvianolic acid ingredient in a red-rooted sage plant can be greatly increased, specifically, the total content of the salvianolicacid ingredient is increased to about 10% from about 6% and is nearly twice of the original total content of the salvianolic acid ingredient, especially the content of the salvianolic acid ingredientin the stems and blades of the red-rooted sage plant can be greatly increased, specifically, the total content of the salvianolic acid ingredients is increased to about 5% from about 1.6% and is nearly more than four times of the original total content of the salvianolic acid ingredient, thus the stems and blades of the red-rooted sage also have values in development and utilization.

Description

technical field [0001] The invention relates to a cultivation technique of Chinese herbal medicine, that is, a cultivation method of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza is the dry root and rhizome of Salvia miltiorrhiza, the plant of Labiatae, and its active ingredients include water-soluble and fat-soluble two categories. The fat-soluble components are mainly diterpene quinone compounds such as tanshinone and cryptotanshinone, and the water-soluble components are mainly phenolic compounds such as tanshinone, protocatechualdehyde, rosmarinic acid, shikonic acid, caffeic acid, salvianolic acid, etc. Phenolic acids have anti-oxidant effects, and are more and more widely used in cosmetics and health products. Salvianolic acid components are currently being studied more, and play an important role in the treatment of cardiovascular diseases, chronic hepatitis, anti-hepatic fibrosis, anti-atherosclerosis, and improvement of memory dysfunction. ...

AI Technical Summary

Problems solved by technology

However, because Salvia miltiorrhiza is a mesophilic medicinal plant, its adaptability is not strong, its cultivation requirements are relatively high, and its yield is not large. However, the content of salvianolic acids in the leaves is low, so there is no development and utilization value
