Embodiment 1

[0026] Such as figure 1 As shown, a method for continuously extracting oil, flavonoids and polysaccharides from Nitraria seeds, comprising the steps:

[0027] S1, separation of filter residue and filtrate: dry the cleaned Nitraria seeds until the moisture content is 4.30%, pass through a 40-mesh sieve after crushing to obtain Nitraria seed powder, then add 95% ethanol according to the liquid-to-material ratio of 10:1mL / g, Reflux extraction at 85°C for 2 times, each time for 2h, suction filtration and combined filtrates to obtain filtrate I and filter residue I.

[0028] S2. Oil extraction: Concentrate the filtrate I in step S1 under reduced pressure at 60°C to obtain the concentrated solution I, dilute it with pure water accounting for 1 / 2 of the volume of the concentrated solution I, and then add 3 times the volume of the diluted concentrated solution The petroleum ether was extracted twice, each time for 30 minutes, and the petroleum ether layer and the water layer were sep...

Abstract

The invention discloses a method for continuously extracting grease, flavone and polysaccharide from nitraria tangutorum seeds. The method comprises the following steps: S1, separating filter residuesand filtrate; S2, extracting the grease; S3, extracting the flavone; and S4, extracting the polysaccharide. The method can be used for continuously extracting the grease, the flavone and polysaccharide compounds from the nitraria tangutorum seeds, the extraction process is simple and feasible, the equipment investment is low, and only one set of extraction equipment is needed. Moreover, materialsdo not need to be taken out of an extraction tank when different components are extracted, time and manpower are saved, and loss of the materials in a transfer process is avoided. According to the preferred scheme, the yield of three active components, namely the grease, the flavone and the polysaccharide, reaches a high value, and the utilization rate of the nitraria tangutorum seeds is improved.

Description

technical field [0001] The invention relates to a method for continuously extracting oil, flavonoids and polysaccharides from Nitraria japonica seeds. Background technique [0002] Nitraria is a multi-branched, saline-alkali-tolerant, xerophytic low shrub of Tribulus terrestris. It has physiological characteristics such as drought resistance, high temperature resistance, and strong water retention. my country's white thorn fruit is rich in resources and widely distributed. It is wild in the deserts of Northwest my country, North China, and the coastal areas of Northeast China, Zhangjiakou Bashang, Tianjin, Cangzhou and other places. According to statistics, the Nitraria in the Qaidam Basin is distributed in pollution-free areas above 3,000 meters above sea level, and can produce 60,000 to 100,000 tons of Nitraria per year, which has great development value. [0003] Nitraria fruit has high economic and medicinal value, and has been well researched and developed. When using...
