Embodiment 1

[0031] Weigh 60kg of shiitake mushrooms, crush them and throw them into a soaking kettle, add 300kg of warm water at 60°C to 70°C, and soak for 1 hour. Stir constantly to obtain the soaking liquid; then use ultrasonic extraction equipment to ultrasonically extract for 40 minutes; pump the filtered extract into the reaction kettle, add 4 times the volume of 60% (volume percentage) industrial ethanol, and pass saturated cooling salt water in the jacket Alcohol analysis began, and after stirring for 30 minutes, the temperature was strictly controlled at 0°C to 5°C. After alcohol analysis for 4 hours, concentrate under reduced pressure to prepare a 10% (mass percentage concentration) lentinan mother drug liquid.

Embodiment 2

[0033] Weigh 20kg shiitake mushrooms, pulverize them and throw them into a soaking kettle, add 400kg of warm water at 60°C to 70°C, soak for 3 hours, stir frequently to obtain soaking liquid; then use ultrasonic extraction equipment to ultrasonically extract for 20 minutes, filter, and pump To the reaction kettle, add 2 times the volume of 80% industrial ethanol, pass through the jacket with saturated cooling saline to start alcohol precipitation, stir for 30 minutes, and strictly control the temperature at 0°C to 5°C. After alcohol analysis for 6 hours, concentrate under reduced pressure to prepare a lentinan mother drug liquid with an active ingredient content of 15% (mass percentage concentration).

Embodiment 3

[0035] Weigh 30kg shiitake mushrooms, pulverize them and throw them into the soaking pot, add 300kg of warm water at 60°C to 70°C, soak for 4 hours, stir frequently to obtain the soaking liquid; then use ultrasonic equipment to ultrasonically extract for 30 minutes, filter, and pump to Add 3 times the volume of 60% industrial ethanol 200kg to the reaction kettle, pass through the jacket with saturated and cooled saline to start alcohol precipitation, and after stirring for 30 minutes, strictly control the temperature at 0°C to 5°C. After alcohol analysis for 4 hours, concentrate under reduced pressure to prepare a lentinan mother drug liquid with an active ingredient content of 20% (mass percentage concentration).

Abstract

The invention relates to a shitake mushroom extract. The shitake mushroom is used as raw materials, and the extraction process comprises a step of ultrasonic extraction. The shitake mushroom extract is not extracted by the traditional enzymolysis method for extracting lentinan. Due to the adoption of the ultrasonic extraction, the time is shortened to 1/3 to 1/4 of that of the traditional method,the temperature is reduced by 30 to 40 DEG C, and the yield is increased by 5 to 30 percent. The method has the advantages of simple technical process, less procedure, short extraction time, resourceconservation and low production cost; and the prepared lentinan has high content of parent medicament and high economic value, is favorable for mass production and has great development space.

Description

technical field [0001] The invention belongs to the field of plant-derived mother medicines of organic agriculture, in particular to an agricultural lentinan mother medicine and a preparation method thereof. Background technique [0002] Due to the use of highly toxic and high residual chemical pesticides, the pollution of water sources, land, livestock, etc. has become increasingly serious, which has seriously threatened the living environment of human beings. At present, environmental protection and food safety have attracted more and more attention. It is an inevitable trend in the development of human society to use modern biological and chemical technology to find new effective active substances with high efficiency and low residues to replace high-toxicity and high-residue compounds. [0003] There are many kinds of plant virus diseases, which are seriously harmful, and the economic losses caused by food production, horticultural crops, and economic crops are about te...
