Problems solved by technology

[0005] Simple extraction of lily alkaloids or polysaccharides, other rich beneficial components of lily such as protein and amino acids have not been effectively utilized, and the single extraction of alkaloids or polysaccharides has a low yield and high cost
The traditional extraction method focuses on the extraction of polysaccharides, but traditional drying or low-temperature drying will cause denaturation and oxidation of some heat-sensitive components, which will reduce the activity of beneficial components in the extract and affect its medical and health effects

Embodiment 1

[0026] Remove the soil and outer skin of the fresh lily, clean it, freeze-dry it to constant weight, crush it to 100 mesh, send it to the extraction tank, add 8 times the water of lily powder, and extract it in an ultrasonic cycle at a temperature of 20 ° C. The ultrasonic frequency is 3800 MHz. , the extraction time is 15min, extract twice, filter to obtain the extract solution I, put the extraction residue into the extraction tank, add water 10 times the extraction residue, microwave extraction at 90°C, the microwave power is 1000W, and the extraction time is 20min , extract once and filter to get the extract II, cool the extract I and extract II, mix them, and concentrate under reduced pressure. The lily active extract is obtained by freeze-drying, and crushed to 150 mesh to obtain lily extract powder.

Embodiment 2

[0028] Remove the soil and outer skin of the fresh lily, clean it, freeze-dry it to constant weight, crush it to 60 mesh, send it to the extraction tank, add water 5 times the lily powder, and extract it in an ultrasonic cycle at a temperature of 40°C. The ultrasonic frequency is 7500MHz , the extraction time is 30min, extract once, filter to obtain the extract solution I, put the extraction residue into the extraction tank, add 8 times the water of the extraction residue, microwave extraction at 70°C, the microwave power is 800W, and the extraction time is 10min , extracted 3 times and filtered to obtain the extract II, the extract I and the extract II were cooled and mixed, then concentrated under reduced pressure, the temperature of the reduced pressure concentration was 50°C, the degree of vacuum was -0.03~-0.09MPa, and the temperature was -3°C The lily active extract was obtained by freeze-drying, and crushed to 200 mesh to obtain lily extract powder.

Embodiment 3

[0030] Remove the soil and outer skin of the fresh lily, clean it, freeze-dry it to constant weight, crush it to 80 mesh, send it to the extraction tank, add 7 times the water of lily powder, and extract it in an ultrasonic cycle at a temperature of 30 ° C. The ultrasonic frequency is 7000 MHz. , the extraction time is 10 minutes, extract 3 times, filter to obtain the extract solution I, put the extraction residue into the extraction tank, add 9 times the water of the extraction residue, and extract by microwave at 80°C, the microwave power is 900W, and the extraction time is 15min , extracted twice and filtered to obtain the extract II, the extract I and the extract II were cooled and mixed, then concentrated under reduced pressure, the temperature of the reduced pressure concentration was 60°C, the degree of vacuum was -0.03~-0.09MPa, and the temperature was -5°C The lily active extract was obtained by freeze-drying, and crushed to 110 mesh to obtain lily extract powder.

Abstract

The invention relates to an active lilium extract, and a preparation method and application of the active lilium extract. The active lilium extract comprises, by mass, 22-35% of proteins, 18-32% of polysaccharide, 20-32% of amino acid and 0.005-0.01% of alkaloid. The preparation method includes a cleaning procedure, a smashing processing procedure, an ultrasonic low-temperature extracting procedure, a microwave intermediate-temperature extracting and a concentrating and drying procedure. The active lilium extract is applied to manufacturing human immunity improving and anti-cancer healthcare products and can be used as an additive of food, wine, tobacco and cosmetics. The active lilium extract, the preparation method and the application have the advantages that active ingredients are prevented from being damaged, and the active component extraction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of extraction and separation of traditional Chinese medicines, and in particular relates to a lily active extract with simple process, high extraction rate and strong activity of active ingredients, its preparation method and application. Background technique [0002] Lily, the name comes from "Shen Nong's Herbal Classic". Lily gets its name because its rhizome is embracing by most fleshy scales and can cure lily disease. The product is the dried fleshy scale leaves of Lilium lancifolium Thunb., Lilium brownii F.E.Brown var. viridulum Baker or Lilium pumilum DC. Lily is widely distributed, and its medicinal uses mainly come from home-grown cultivars. Mainly produced in Jiangsu, Hunan, Lanzhou, Gansu and other places. [0003] Lily has the effect of nourishing yin, nourishing the lung and relieving cough. It is used for dry-hot cough caused by lung yin deficiency, chronic cough due to lung deficiency, hemo...
