Embodiment 1

[0060] Take by weighing 50g of air-dried Schisandra fruit powder, put it into a round bottom flask, then add 0.8mol / L of [C 6 mim] Cl ionic liquid aqueous solution, put it into a microwave extraction device, connect it with an essential oil extractor, and irradiate with 600W microwave for 30 minutes. After the extraction is completed, steam and extract are obtained. Collect the steam in the essential oil extractor, then condense the steam, let it stand for stratification, wherein the upper layer is an oil phase, and the lower layer is an aqueous phase, and the upper layer oil phase is dried with anhydrous sodium sulfate to obtain 0.675 mL of Schisandra essential oil. The rate was 13.5 mL / kg. Filter the extract, collect the supernatant, cool, slowly add absolute ethanol until the volume ratio of absolute ethanol to extract is 3:1, centrifuge at 6000r / min for 10min, discard the supernatant to obtain Schisandra polysaccharide, Schisandra chinensis The mass of the polysaccharide ...

Embodiment 2

[0063] Take by weighing 1000g of air-dried Schisandra fruit powder, put it into a round bottom flask, then add 0.6mol / L of [C 4 mim] Br ionic liquid aqueous solution, put it into a microwave extraction device, connect it with an essential oil extractor, 700W microwave radiation for 40min, after the extraction is completed, get steam and extract. Collect the steam in the essential oil extractor, then condense the steam, and let it stand for stratification. The upper layer is an oil phase, and the lower layer is an aqueous phase. The upper oil phase is dried with anhydrous sodium sulfate to obtain 15.8 mL of Schisandra essential oil. The rate was 15.8 mL / kg. Filter the extract, collect the supernatant, cool, slowly add absolute ethanol until the volume fraction of ethanol is 4:1, centrifuge at 12000r / min for 5min, discard the supernatant to obtain Schisandra polysaccharide, the mass of Schisandra polysaccharide is 88.7g , the yield of Schisandra polysaccharide was 88.7g / kg.

Abstract

The invention provides a method used for simultaneous extraction of Chinese magnoliavine fruit polysaccharides and essential oil. The method comprises following steps: Chinese magnoliavine fruits andan ionic liquid aqueous solution are mixed, and are subjected to microwave extraction so as to obtain steam and an extracted solution; the steam is subjected to condensation and drying treatment so asto obtain Chinese magnoliavine essential oil; the extracted solution is subjected to alcohol precipitation treatment and solid liquid separation successively so as to obtain Chinese magnoliavine fruit polysaccharides. The method can be used for simultaneous extraction of Chinese magnoliavine fruit polysaccharides and essential oil; the Chinese magnoliavine fruit polysaccharides and essential oilyield is relatively high; it is shown by experiment results that the Chinese magnoliavine fruit polysaccharides yield ranges from 78.3 to 88.7g / kg, and the Chinese magnoliavine fruit essential oil yield ranges from 13.5 to 15.8ml / kg.

Description

technical field [0001] The invention relates to the field of extracting active components in natural products, in particular to a method for simultaneously extracting schisandra polysaccharide and schisandra essential oil. Background technique [0002] Schisandra chinensis is mainly produced in North China and Northeast my country. It is a famous authentic medicinal material in Changbai Mountain. The main chemical components of Schisandra chinensis include polysaccharides, essential oils, lignans and anthocyanins. [0003] Schisandra polysaccharides have the functions of inhibiting lipid peroxidation, scavenging free radicals, increasing the activity of antioxidant enzymes and protecting biological membranes. Schisandra essential oil is volatile and easily absorbed by the human body, and can quickly penetrate human organs to regulate hormone secretion, balance body functions, antibacterial, and skin care. [0004] In the current prior art, polysaccharides from Schisandra c...
