Method for increasing rare saponin content in ginseng plant

Abstract

The invention provides a method for increasing the rare saponin content in a ginseng plant. The method includes the following steps that 1, cleaning is carried out; 2, ultrahigh pressure cell wall-breaking is carried out, wherein the completely-cleaned ginseng plant is put in a plastic bag, the plastic bag is filled with water, air in the bag is exhausted, and the plastic bag is sealed; the plastic bag filled with the ginseng plant is put in ultrahigh pressure equipment, the pressure is raised to 100-600 MPa, and after the pressure value is kept for 1-10 min, the pressure is rapidly released; after ultrahigh pressure treatment is completed, cell walls of the ginseng plant are broken; 3, cooking is carried out; 4, fermentation is carried out, wherein the ginseng plant cooked in the step 3 is put in a container, fermentation is carried out at the temperature kept at 35-95 DEG C and the humidity kept at 60%-100%, and processing is completed 20-50 days later. Through the combined process of ultrahigh pressure wall breaking, cooking and fermentation, peak values of ginseng and American ginseng rare saponin conversion are found, the rare saponin conversion efficiency is high, and the maximal rare saponin content can reach 4.05%.

Description

technical field [0001] The invention relates to the technical field of plant processing and extraction, in particular to a method for increasing the content of rare saponins in ginseng plants. Background technique [0002] Ginseng and American ginseng are perennial herbaceous plants of the genus Panax in Araliaceae. One of the main active ingredients in ginseng and American ginseng is a class of chemical substances called "ginsenosides (GS)", which can regulate the central nervous system of the human body, improve the It has many functions such as human immunity, heart strengthening, anti-fatigue, anti-aging, etc. It has a good therapeutic effect on various diseases of the nervous system, cardiovascular system, endocrine system and reproductive system. [0003] Common ginseng and American ginseng only contain (or do not contain) very small amounts of rare ginseng saponins such as S-Rg3, R-Rg3, Rg5, Rk1, and Rh2. Rare saponins have a strong ability to resist tumor formation ...

Problems solved by technology

Some of the above methods need to consume a lot of energy, and some will complicate the processing process, have a certain degree of environmental pollution, and the increase in the content of rare saponins is not ideal.
