Problems solved by technology

[0008] Schisandra chinensis extract Since Schisandra chinensis contains sugars and a large amount of organic acids, 5-HMF is easily generated during the extraction process, resulting in a higher overall 5-HMF level
The schisandra extract is dried in a decompression drying oven. After drying, the 5-HMF content of the extract decreases less, about 5%-20%. After drying, the extract is dark and sticky, which is not conducive to preservation and affects product quality.

Embodiment 1 5

[0048] The preparation of embodiment 1 schisandra extract

[0049] Add water to decoct Schisandra chinensis three times, add 7 times of water for the first time and decoct for 1 hour, add 6 times of water for the second time and decoct for 45 minutes, add 6 times of water for the third time and decoct for 30 minutes, combine the extracts, and decoct at 75°C Concentrate under pressure to a relative density of 1.16-1.21 (50°C), add ethanol until the alcohol content is 75%, place the liquid below 13°C, filter, and concentrate the filtrate under reduced pressure to a relative density of 1.18-1.23 (50°C) below 75°C ℃), add ethanol until the alcohol content is 85%, place the liquid below 13°C, filter, add 40% sodium hydroxide solution to adjust the pH to 7, place the liquid below 13°C, filter, and the filtrate is below 75°C Concentrate under reduced pressure to a relative density of 1.03-1.13 (50°C), and dry under reduced pressure below 70°C to obtain Schisandra chinensis extract. ...

Embodiment 2

[0051] Weigh 18.6L of the Schisandra chinensis extract of Example 1, and dry it under reduced pressure in a vacuum drying oven; the vacuum degree is controlled at -0.065~-0.085MPa, the temperature is controlled at 65±5°C, and the drying time is 48h. Cool down to obtain 4.8kg of dry extract. The moisture content of the extract was 9.2%, the 5-HMF content was 10.9 mg / g, and the extract was dark in color, sticky and agglomerated.

Embodiment 3

[0053] Weigh 15.4L of the Schisandra chinensis extract of Example 1, do not pre-freeze the extract concentrate, and use a vacuum freeze dryer to directly dry under reduced pressure; first cool the product to 15°C, turn on the vacuum, and wait for the vacuum degree to be displayed , control the vacuum degree and open the limited leakage and keep the limited leakage value at ±10Pa, so that the surface of the liquid medicine will continue to fluctuate, keep the state of broken bubbles, and gradually increase the vacuum degree, raise the temperature to 55°C, and dry After 35.67 hours, cool down to 20-25°C to obtain 3.98kg of dry extract. The moisture content of the extract is 3.7%, the 5-HMF content is 2.6 mg / g, and the extract is light in color, non-sticky and loose.

Abstract

The invention relates to a drying method of a traditional Chinese medicine extract, in particular to a drying method controlled by 5-HMF of a schisandra extract. The method comprises the following steps: step 1, weighing the Schisandra chinensis extract; step 2, placing it in a vacuum freeze dryer; step 3, cooling the product; step 4, turning on the vacuum and maintaining a limited leakage value; step 5, gradually increasing the The degree of vacuum and the temperature make the surface of the liquid medicine fluctuate continuously and keep the state of broken bubbles; step 6, cooling down to obtain a dry extract.

Description

Technical field: [0001] The invention relates to a drying method of a traditional Chinese medicine extract, in particular to a drying method controlled by 5-HMF of the Schisandra chinensis extract. Background technique: [0002] Schisandra chinensis, commonly known as mountain pepper, weight dumpling, medicine schisandra, noodle vine, Wumeizi, etc., Tang et al. "Xinxiu Materia Medica" contains "five flavors are sweet and sour in the flesh, hard in the core, and have a salty taste", so it has the name of schisandra. Ancient medical books call it Chuzhu, Xuanji, and Huiji, which were first listed in the top grade of Shennong’s Herbal Classic. The efficacy of traditional Chinese medicine lies in the power of nourishing and strengthening, and its medicinal value is extremely high. [0003] Its main components include: chemical components such as lignans, sugars, terpenes and organic acids, among which lignins mainly include schizandrin, de-oxyschizandrin, neoschizandrin ), Schi...
