Problems solved by technology

Fatigue is a relatively broad concept, because the physiological and pathological causes of fatigue are diverse. According to traditional Chinese medicine and health preservation, kidney deficiency and qi deficiency, overwork, disharmony of qi and blood, and trance may all cause fatigue. Fatigue, and fatigue can lead to physical weakness, decreased immunity, sluggish brain response, premature aging and other phenomena. Although fatigue does not cause death directly and quickly like cancer and heart disease, it is a disease that endangers modern people. Invisible killers also cause great harm to human health

Embodiment 1

[0014] Example 1: Preparation of Wisteria Extract 1

[0015] (a) Mix 5kg of dried wisteria and licorice (accounting for 10% of the total weight), crush them, extract with 75% ethanol solution under heat reflux (20L x 3 times), combine the extracts, concentrate until there is no alcohol smell to obtain an ethanol extraction concentrate (b) Dilute the ethanol extraction concentrate obtained in step (a) with water (3L), and extract with petroleum ether (3L×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol (3L ×3 times), concentrated under reduced pressure to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (c) n-butanol extract was dissolved in water, filtered, and enriched with AB-8 macroporous resin For active ingredients, wash 8 column volumes with 15% ethanol to remove large polar components, then elute 10 column volumes with 55% ethanol, collect the 55% ethanol eluate, and concentrate under reduced pressure.

Embodiment 2

[0016] Embodiment 2: Preparation of wisteria extract 2

[0017] (a) Mix 5kg of dried wisteria and licorice (accounting for 5% of the total weight), pulverize, extract with 70% ethanol solution under heat reflux (20L x 3 times), combine the extracts, concentrate until there is no alcohol smell to obtain an ethanol extraction concentrate (b) Dilute the ethanol extraction concentrate obtained in step (a) with water (3L), and extract with petroleum ether (3L×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol (3L ×3 times), concentrated under reduced pressure to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (c) n-butanol extract was dissolved in water, filtered, and enriched with AB-8 macroporous resin For active ingredients, wash 10 column volumes with 10% ethanol to remove large polar components, then elute 12 column volumes with 50% ethanol, collect the 50% ethanol eluate, and concentrate under reduced pressure.

Embodiment 3

[0018] Embodiment 3: the preparation of wisteria extract

[0019] (a) Mix 5kg of dried wisteria and licorice (accounting for 15% of the total weight), crush them, extract them under reflux with 80% ethanol solution, combine the extracts (20L x 3 times), concentrate until there is no alcohol smell to obtain an ethanol extraction concentrate ; (b) Dilute the ethanol extraction concentrate obtained in step (a) with water (3L), and then use petroleum ether (3L×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol (3L×3 times) 3 times) extraction, concentration under reduced pressure to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (c) n-butanol extract was dissolved in water, filtered, enriched with AB-8 macroporous resin For the active ingredient, wash 6 column volumes with 20% ethanol to remove large polar components, then elute 8 column volumes with 60% ethanol, collect the 60% ethanol eluate, and concentrate under reduce...

Abstract

The invention discloses application of Chinese wistaria extract to preparation of health food capable of relieving physical fatigue. The Chinese wistaria extract is prepared by the following method: (a) mixing and crushing dried Chinese wistaria and licorice, performing heat reflux extraction by virtue of a 70 to 80 percent ethanol solution, mixing extracting solutions, and performing concentration until ethanol smell is removed to obtain an ethanol extracting concentrated solution; (b) diluting the ethanol extracting concentrated solution obtained in step (a) with water, and performing extraction and reduced pressure concentration sequentially with petroleum ether, ethyl acetate and water saturated n-butyl alcohol to obtain petroleum ether extract, ethyl acetate extract and n-butyl alcohol extract respectively; (c) dissolving the n-butyl alcohol extract in water, performing filtration, enriching active ingredients by virtue of AB-8 type macroporous resin, flushing a volume of 6 to 10 columns with 10 to 20 percent ethanol to remove large polar components, eluting a volume of 8 to 12 columns with 50 to 60 percent ethanol, collecting 50 to 60 percent ethanol eluent, and performing reduced pressure concentration, wherein the amount of the licorice based on the total weight of the Chinese wistaria and the licorice is 5 to 15 percent.

Description

technical field [0001] The invention relates to the field of food, in particular to the application of wisteria extract in preparing health food for alleviating physical fatigue. Background technique [0002] With the development of society, the advancement of science and technology, the acceleration of the pace of life, the richness of material life, the higher and higher requirements for spiritual life, and the acceleration of people's life rhythm, the incidence of fatigue will inevitably increase sharply, and people are prone to fatigue. It has become a common phenomenon among adults. Fatigue is a relatively broad concept, because the physiological and pathological causes of fatigue are diverse. According to traditional Chinese medicine and health preservation, kidney deficiency and qi deficiency, overwork, disharmony of qi and blood, and trance may all cause fatigue. Fatigue, and fatigue can lead to physical weakness, decreased immunity, sluggish brain response, prematu...
