Description

Ginseng and cassia seed compound fermentation liquor and preparation process thereof
Technical Field
The invention belongs to the technical field of traditional Chinese medicine development, and particularly relates to a ginseng and cassia seed compound fermentation broth and a preparation process thereof.
Background
In recent years, modern people often have accelerated life rhythm and increasingly vigorous competition, and sub-health people are increasingly huge along with the continuous increase of social relations and family pressure. Studies show that about 80% of the current population is in sub-health state. Sub-health status is divided into sub-health status of body, sub-health status of psychology, sub-health status of social interaction, etc. People in sub-health state, though not clear disease, have reduced mental activity and adaptability, if the state can not be corrected in time, the mental disease is very easy to cause.
The sub-health people are more and more, the health care products on the market have certain limitation, side effects can be brought to the body, and the large-multivalent price is expensive, so that additional economic burden is brought to the life of people. Compared with Western medicine, the traditional Chinese medicine has less adverse reaction. The Chinese herbal compound has various chemical components, has the characteristics of multiple targets, multiple layers and multiple curative effects, and can increase the activity of the Chinese herbal compound by correct compatibility. However, the traditional Chinese medicine decoction has large dosage, inconvenient carrying and poor sensory properties, and cannot be produced commercially. Therefore, it is necessary to develop a fermentation broth which is convenient to carry and has better sensory properties, is convenient for people to take for a long time, achieves the effect of enhancing immunity, improves sub-health, and has important practical significance for developing Chinese medicine resources and improving economic value.

Results 7 results
HPLC chromatograms are shown in FIG. 13 and the measurement results are shown in Table 7. The chemical components in the ginseng and cassia seed compound before and after fermentation have obvious difference, the content of cordycepin and luteolin is obviously increased, and the difference before and after fermentation is 0.0822,0.1273 respectively; the content of luteolin is obviously reduced, and the difference value before and after fermentation is 0.0411. The content of chlorogenic acid is slightly reduced, and the difference value before and after fermentation is 0.0090; the content of chrysophanol has no obvious change, and the difference value between the chrysophanol before and after fermentation is 0.0027. The reduced amount of luteolin and the increased amount of luteolin indicate that fermentation not only causes cleavage of glycosidic bonds in luteolin to produce luteolin, but also causes conversion between compounds. Meanwhile, the content of cordycepin is increased after fermentation, which indicates that a certain conversion relationship exists between cordycepin and adenosine. The content of chlorogenic acid after fermentation is slightly reduced, and it is presumed that chlorogenic acid undergoes an enzymatic hydrolysis reaction in the fermentation process to cause ester bond cleavage, and caffeic acid or quinic acid is generated, and further conversion of caffeic acid occurs to produce 3-hydroxy phenylpropionic acid, p-coumaric acid, ferulic acid, and the like. Because the solubility of the chrysophanol in water is smaller, the chrysophanol content in the solution is smaller, and the content change before and after fermentation is not obvious. Experimental results further show that the fermentation can convert the components in the compound; not only can lead to the cleavage of glycosidic bonds of chemical components, but also can reduce the molecular weight and convert the glycosidic bonds into small molecular substances which are easier to digest and absorb by human bodies.
