Embodiment 1

[0026] Dry the bark of sumac tree at 40°C to constant weight, and measure the moisture content to be 7-10%, then crush it with a high-speed shearing machine, and pass through a 20-80 mesh screen to obtain skin powder; put the skin powder into the grinding In the tool, add activated carbon, the ratio of skin powder to activated carbon is 1:1~1:20 (g:g), grind for 1~10min, make it mix evenly, and obtain the mixture; transfer the mixture to a container with a filter device, Wash and extract with methanol, the ratio of the mixture to methanol is 1:1~1:10 (g:mL), control the washing speed to 0.1~2mL / min, and wash to obtain the extract, and the extract is stored at 40~60℃ The solvent was recovered by evaporation under reduced pressure, and the sumac flavonoids and phenolic acid compounds were obtained after drying, and the calculated compound yield was 6%.

Embodiment 2

[0028] Dry the bark of sumac tree at 40°C to constant weight, and measure the moisture content to be 7-10%, then crush it with a high-speed shearing machine, and pass through a 20-80 mesh screen to obtain skin powder; put the skin powder into the grinding In the tool, add carbon nanotubes, the ratio of skin powder to carbon nanotubes is 1:1~1:20 (g:g), grind for 1~10min, make it mix evenly, and obtain a mixture; transfer the mixture to a filter device In a container, ethanol is used for leaching and extraction, the ratio of mixture to ethanol is 1:1~1:10 (g:mL), the rinsing speed is controlled at 0.1~2mL / min, and the extract is obtained by leaching, and the extract is in The solvent was evaporated under reduced pressure at 40-60°C, and the sumac flavonoids and phenolic acid compounds were obtained after drying. The calculated compound yield was 6.58%.

Embodiment 3

[0030] Dry the wood part of the lacquer tree at 40°C to constant weight, and measure the moisture content to be 7-10%, then crush it with a high-speed shearing machine, and pass through a 20-80 mesh screen to obtain wood powder; put the wood powder into the grinding In the tool, add florisil, the ratio of wood flour to florisil is 1:1~1:20 (g:g), grind for 1~10min, mix it evenly, and get the mixture; transfer the mixture Put it into a container with a filter device, rinse and extract with 70% methanol water, the ratio of the mixture to 70% methanol water is 1:1~1:10 (g:mL), and control the washing speed to 0.1~2mL / min , eluted to obtain the extract, the extract was evaporated under reduced pressure at 40-60°C to recover the solvent, and dried to obtain sumac flavonoids and phenolic acid compounds, the calculated compound yield was 9%.

Abstract

The invention discloses a method for rapidly extracting flavone and a phenolic acid compound from lacquer trees at normal temperature. The method comprises the following steps that lacquer tree bark or lacquer tree wood part are dried at low temperature to constant weight, crushed, mixed with a dispersion matrix, uniformly ground, leached and extracted by using an extraction solvent, and concentrated to finally obtain the lacquer tree flavone and the phenolic acid compound. Compared with a conventional extraction method, the method has the advantages that heating is not needed, damage to raw material components is little, the operation process is simple, the product yield is high, and the obtained lacquer tree flavone and the phenolic acid compound has good color and luster and can be applied to the fields of oxidation resistance, fatigue resistance and the like.

Description

technical field [0001] The invention relates to the extraction of sumac flavonoids and phenolic acid compounds, in particular to a rapid extraction method at room temperature, which belongs to the technical field of extraction of phytochemical components. Background technique [0002] Sumac tree is an important economic forest tree species in my country, and its secretion lacquer is a natural resin coating, known as the "king of coatings". The seed skin of sumac fruit can be pressed to produce wax, the seed core can be pressed to produce oil, and the wood texture is solid. Sumac grows quickly and is a dual-purpose species for natural paint, oil and wood. Sumac also has excellent medicinal value. The leaves, flowers, roots, bark, seeds, dried lacquer and wood of sumac can be used as medicine. Historically, sumac has been used as a traditional Chinese medicine for the treatment of gastroenteritis, heart disease, arthritis, high blood pressure, diabetes, stroke, and chronic f...
