Embodiment 1

[0033] A method for extracting a tartary buckwheat extract rich in tartary buckwheat flavonoids, comprising the following steps:

[0034] ①After the tartary buckwheat bran, tartary buckwheat leaves and tartary buckwheat stalks are crushed or pulverized, they are extracted with 70% ethanol in a hot reflux extractor at a pressure of 0.15Mpa and a temperature of 80°C for 5 hours, and the extract is filtered and dried. Refrigerate at -5°C until ethanol is precipitated, filter to obtain a filtrate containing tartary buckwheat flavonoids, and recover the ethanol for later use;

[0035] ②The filtrate obtained in step ① was evaporated and concentrated for 5 hours at a pressure of 0.05Mpa and a temperature of 80°C;

[0036] ③ Then collect the paste for 5 hours under the conditions of vacuum degree of -0.06Mpa and steam pressure of 0.05Mpa;

[0037] ④Finally, dry for 20 hours under the conditions of vacuum degree of -0.08Mpa and steam pressure of 0.1Mpa, and then pulverize.

Embodiment 2

[0039] A method for extracting a tartary buckwheat extract rich in tartary buckwheat flavonoids, comprising the following steps:

[0040] ① After the tartary buckwheat bran, tartary buckwheat leaves or tartary buckwheat stalks are crushed or pulverized, they are extracted with 80% ethanol in a hot reflux extractor at a pressure of 0.2Mpa and a temperature of 78°C for 6 hours, and the extract is filtered and dried. Refrigerate at -5°C until ethanol is precipitated, filter to obtain a filtrate containing tartary buckwheat flavonoids, and recover the ethanol for later use;

[0041] ②The filtrate obtained in step ① was evaporated and concentrated for 6 hours at a pressure of 0.1Mpa and a temperature of 78°C;

[0042]③ Then collect the paste for 4 hours under the condition of vacuum degree of -0.07Mpa and steam pressure of 0.1Mpa;

[0043] ④Finally, dry for 18 hours under the conditions of vacuum degree of -0.09Mpa and steam pressure of 0.15Mpa, and then pulverize.

Embodiment 3

[0045] A hypoglycemic capsule is obtained by crushing the tartary buckwheat extract rich in tartary buckwheat flavonoids obtained in Example 1 through a No. 5 sieve, and filling the capsules in a capsule filling machine under a vacuum of -0.04Mpa. How to take the product: The specification is 80mg / capsule, take it before meal, three times a day, three capsules at a time.

Abstract

The process of extracting tartary buckwheat extract with rich tartary buckwheat flavone includes the following steps: 1. extracting tartary buckwheat bran, tartary buckwheat leaf and / or tartary buckwheat stalk with alcohol in an extractor for 4-6 hr, filtering the extracted liquid, cold storing at 0-5 deg.c to separate out alcohol and filtering to obtain filtrate and recover alcohol; 2. evaporating the filtrate to concentrate for 4-6 hr; 3. further concentrating for 4-6 hr to obtain extractum; and 4. drying for 18-22 hr. The tartary buckwheat extract with rich tartary buckwheat flavone may beused in different kinds of health food. The process of the present invention has short period, low cost, high yield and other advantages.

Description

technical field [0001] The invention relates to a method for extracting bioflavonoids and a product thereof, in particular to a method for extracting a tartary buckwheat extract rich in tartary buckwheat flavonoids and a product thereof. Background technique [0002] Tartary buckwheat has a history of both medicine and food since ancient times. "Shen Nong Shu" records: Tartary buckwheat is "the king of whole grains". "Compendium of Materia Medica" records: Tartary buckwheat is bitter in taste and cold in nature. It can strengthen the stomach, strengthen the energy, refresh the spirit, benefit the eyes and ears, and refine the five internal organs. "Depressing qi and widening the intestines to grind and stagnate, reduce heat, swelling and pain, remove white turbid blood bands, and accumulate diarrhea." "Qian Jin Yao Fang" records: it can calm the nerves, activate qi and blood, lower qi and widen the intestines, clear away heat, swelling, wind and pain, Eliminate accumulation...
