Problems solved by technology

[0004] The problems existing in the above-mentioned methods: the seed dregs after extracting seabuckthorn oil from seabuckthorn seeds are not used and discarded; the methods of extracting seabuckthorn flavonoids and seabuckthorn polysaccharides are separated and implemented separately, and the raw materials are resources except for the secondary use of the peel. Direct utilization, with the technical purpose of extracting individual substances, not only involves repeated processing in the process, but also time-consuming; because seabuckthorn seed residues are not used in depth, the added value of deep utilization of resources is not generated and the industrial chain is also short, not only the extraction of seabuckthorn oil The cost is high, and the discarded seabuckthorn seed dregs after oil refining may cause secondary pollution

Embodiment Construction

[0020] Example Simultaneous fractional extraction of seabuckthorn flavonoids and seabuckthorn polysaccharides from seabuckthorn seed dregs

[0021] This embodiment operates completely according to the above-mentioned operation steps, which are briefly described as follows.

[0022] The first step seabuckthorn seed dregs 100g, (wherein the total sugar content is 6.23%, the reducing sugar content is 2.74%, the fat content is 1.74%, the flavonoid content is 2.63%, the water content is 10%, and the other is 77.66%), with 500g of 70% ethanol As a solvent, reflux at 70°C to extract seabuckthorn flavonoids, collect the reflux liquid, concentrate the reflux liquid to 100g under reduced pressure, and recover the ethanol solvent at the same time, absorb it on a macroporous resin column, elute with water first, and then elute with 40% ethanol , collect the eluent, concentrate under reduced pressure, and recover ethanol at the same time, dry the concentrate under vacuum at low temperature...

Abstract

This invention relates to simultaneous extraction of sea-buckthorn seed dregs to produce sea-buckthron flavone and sea-buckthorn polyose. The prodn. procedures are: hot alcohol refluxing concentration, absorption, washing-off separation to obtain sea-buckbron flavone. The dregs from above-said procedure is then proceeded steps of: hot water extraction, concentation, removing protein, alcohol settling, crystalization to obtain sea-buckthorn polyose. Advantages are: the raw material is industrial waste for oil prodn. from sea-buckthron; single process for obtain two products simutaneously, recovery of solvent, waste dregs can be reused to produce fertilizer, waste liquid can be recirculation after purifying.

Description

technical field [0001] The invention relates to a method for simultaneously extracting seabuckthorn flavonoids and seabuckthorn polysaccharides from seabuckthorn seed dregs by fractionation, and belongs to the technical field of traditional Chinese medicine preparation. Background technique [0002] Seabuckthorn (Hippophae rhamnoides L), also known as vinegar willow, belongs to the family Elaeagnaceae and is a plant with both food and medicine. [0003] Existing technology for extracting seabuckthorn flavonoids and seabuckthorn polysaccharides: the raw material for extracting seabuckthorn flavonoids mainly adopts seabuckthorn oil (the paper "Characteristics of seabuckthorn oil and supercritical CO 2 Extraction process", Gansu Textile Science and Technology, 1998, (4): 22-27), seabuckthorn fruit and leaves, also useful peel residue, pulp (Zhu Wanjing and Ni Peide's paper "Development of seabuckthorn resources and extraction of seabuckthorn flavonoids", C...
