Embodiment 1

[0114] 5kg Tanaka root is powdered, and crosses a 70-mesh sieve to obtain Tanaka powder with an average mesh number of 70. Add 150kg of 60% 1,3-butanediol solution to the Tanaka powder, stir evenly, and place In a microfluidic extractor, the extraction was carried out under the conditions of a refrigerant temperature of 20° C. and a feed rate of 20 L / min to obtain an extract.

[0115] The above extract was pumped into a high-speed centrifuge for solid-liquid separation at a centrifugal speed of 17000 rpm, and the separated liquid was collected. Then the separation liquid is pumped into the membrane treatment system, and the 0.5 μm microporous membrane and the 7000 Da ultrafiltration membrane are used to remove impurities and purify in sequence to obtain the membrane separation liquid.

[0116] Concentrate the above-mentioned membrane separation liquid under reduced pressure under reduced pressure. The conditions for concentrated under reduced pressure under reduced pressure ar...

Embodiment 2

[0118] 5kg Tanaka root is powdered and passed through a 80-mesh sieve to obtain Tanaka powder with an average mesh number of 80. Add 200kg of 20% 1,3-butanediol and 20% 1,2-butanediol to the Tanaka powder. The propylene glycol (w / w) mixed solution was stirred evenly, placed in a microfluidic extractor, and extracted at a refrigerant temperature of 30° C. and a feed rate of 5 L / min to obtain an extract.

[0119] The above extract was pumped into a high-speed centrifuge for solid-liquid separation at a centrifugal speed of 18000 rpm, and the separated liquid was collected. Then the centrifugate is pumped into the membrane treatment system, and the 0.4μm microporous membrane and 8000Da ultrafiltration membrane are used to remove impurities and purify in sequence to obtain the membrane separation fluid.

[0120] Concentrate the above-mentioned membrane separation liquid under reduced pressure under reduced pressure. The conditions for concentrated under reduced pressure under reduce...

Embodiment 3

[0122] 5kg Tanaka root is powdered and passed through a 40-mesh sieve to obtain Tanaka powder with an average mesh number of 40. Add 165kg of 30% 1,3-butanediol and 40% 1,2-butanediol to the Tanaka powder. The propylene glycol (w / w) mixed solution was stirred evenly, placed in a microfluidic extractor, and extracted at a refrigerant temperature of 10° C. and a feed rate of 20 L / min to obtain an extract.

[0123] The above extract was pumped into a high-speed centrifuge for solid-liquid separation at a centrifugal speed of 18000 rpm, and the separated liquid was collected. Then the centrifugate is pumped into the membrane treatment system, and the 0.3μm microporous membrane and the 9000Da ultrafiltration membrane are used to remove impurities and purify in sequence to obtain the membrane separation fluid.

[0124] Concentrate the above-mentioned membrane separation liquid under reduced pressure under reduced pressure. The conditions for concentrated under reduced pressure under...

Abstract

The invention belongs to the field of technologies for extracting plants, and particularly relates to a method for extracting thanakha. The method for extracting the thanakha includes carrying out micro-jet extraction on thanakha powder to obtain extract. The method has the advantages that the method is high in extraction efficiency, flavonoid compounds in the thanakha are rarely destroyed, the thanakha extract extracted by the aid of the method is high in total flavonoid content, the method is beneficial to realizing effects of the thanakha, and the total flavonoid content of the thanakha canreach 4-10 mg / mL under the condition of the relative density of 1.020-1.080; the method is easy to implement and suitable for industrial popularization and application; as proved by experimental results, the thanakha extract extracted by the aid of the method is high in safety, obvious broad-spectrum ultraviolet absorption effects can be realized by the thanakha extract, and diversified free radicals can be scavenged by the thanakha extract.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a method for extracting Tanaca. Background technique [0002] Thanaka, also known as Hesperethusa crenulata, belongs to the Rutaceae Citrus genus and is a tropical plant that grows in the Indian subcontinent and Southeast Asia. In Myanmar, people often grind the bark of neem bark into powder, mix it with water and apply it on the face, which has multiple functions such as sun protection, cooling and beauty. Because neem has no toxic side effects on the skin and is a natural cosmetic, it is very popular in the local area. However, if the bark of Neem bark is directly ground and used, the active ingredients are not dissolved, the actual effect is poor, and it affects the appearance, the use range is narrow, and other disadvantages, so it is necessary to extract its active ingredients to enhance its applicability. [0003] Jiang Shan et al. used methanol, etha...
