Problems solved by technology

Because the evaluation of product quality by color value can only observe the change of solution color in the range of visible light, which to a large extent reflects only the change of anthocyanin components in it, and cannot characterize the overall change of the types and contents of its various functional substances. Proanthocyanidins, chlorogenic acid, tannins and other substances have no absorption peaks in the visible light range, so the above method cannot detect their content changes
Therefore, it is difficult to obtain deep-processed Pyracantha products with excellent biological activity and stable and consistent quality through this material extraction process based on the color price evaluation method. This is also a key scientific and technical problem that needs to be solved urgently in the industrial development of Pyracantha.
[0005] The above situation shows that at present, there is no preparation technology and product for the simultaneous utilization of multiple functional components in Pyracantha, as well as a standardized production and testing system that can comprehensively and effectively control the quality of the product. The effectiveness and quality of Pyracantha extract Controllability research needs to be improved, which seriously hinders the market application of fireacantha deep-processing products

Embodiment 1

[0036] Embodiment 1: the preparation of the standard extract of pericarp flesh of Acanthopanax fruit

[0037] (1) the dry powder obtained by directly pulverizing the peel and flesh of the fresh fruit of Pyracantha japonicus after being dried and the peel and flesh of the dried fruit of which the seeds are removed is used as raw material;

[0038] (2) The raw materials are extracted by solvent reflux, filtered to obtain an extract, and concentrated in a vacuum until the solid content is 70-80%, to obtain the standard extract of the peel and flesh of Pyracantha japonicus. Solvent reflux extraction process parameters are shown in Table 1, and vacuum concentration process parameters are shown in Table 2.

Abstract

The invention discloses a peel and pulp standard extract of wild pyracantha fortuneana fruit, which is prepared by using dry powder, which is obtained by drying and grinding peel and pulp of seeded fresh wild pyracantha fortuneana fruit or obtained by directly grinding the peel and pulp of seeded dry wild pyracantha fortuneana fruit, as a raw material and by refluxing extraction in a solvent, filtering to obtain extract solution and condensing under vacuum till the solid matter content is 70 to 80 percent. The standard extract contains 0.02 to 0.5 weight percent of anthocyanin, 6 to 12 weightpercent of proanthocyanidins, 0.9 to 5 weight percent of general flavones and 2 to 5 weight percent of hydrolysable plant polyphenol. The overall effect of the peel and pulp standard extract of the wild pyracantha fortuneana fruit is demonstrated by multiple components and the mutual synergic effect among the multiple components, the peel and pulp standard extract of the wild pyracantha fortuneana fruit has the remarkable antioxidative, whitening and blood fat reducing effects and other effects and can be used as a high-quality material for preparing blood fat reducing foods, whitening cosmetics and food additives.

Description

technical field [0001] The invention relates to a standard extract of the peel and flesh of Acanthopanax fruit and its preparation method and application, especially the application in the aspects of anti-oxidation, blood fat-lowering functional food, whitening cosmetics and food additives. Background of the invention [0002] Pyracantha fortuneana (Pyracantha fortuneana) is the fruit of the Pyracantha plant of the Rosaceae Apple subfamily. It is used for both medicine and food. Folks in the producing areas have dried it in the sun and used it as a food substitute, which is extremely safe. The medicinal records of Pyracantha fruit first appeared in "Southern Yunnan Materia Medica". The fruit has a dry and sour taste, and its medicinal properties have the effects of invigorating the spleen and eliminating accumulation, promoting body fluid and quenching thirst, clearing heat and detoxifying, promoting blood circulation and stopping bleeding. "Compendium of Materia Medica" onc...
