Embodiment 1

[0032] Cut 1000g Phellinus Phellinus fruiting bodies into appropriate small pieces, put into a high-speed traditional Chinese medicine pulverizer and pulverize, and the pulverization fineness reaches 60 mesh. The pulverized Phellinus powder was mixed with 6L deionized water, and placed in an ultrasonic extractor for ultrasonic extraction. The ultrasonic temperature is 60°C, the ultrasonic time is 30min (2 seconds on, 3 seconds off), and the ultrasonic power is 1000W. Centrifuge at 5000rpm for 10min, and re-operate the obtained precipitate according to the above-mentioned ultrasonic extraction conditions. Centrifuge at 5000 rpm for 10 min, and combine the supernatant obtained after two extractions and centrifugation. Concentrate the extract to 1 / 3 of the original volume in a rotary evaporator, and add three times the volume of absolute ethanol to the concentrate. Centrifuge at 5000rpm for 10min, place the resulting precipitate into a dialysis bag with a membrane cut-off molec...

Embodiment 2

[0034] An aqueous two-phase system of 18% PEG1000 and 14% KPi (pH 6.8) was prepared, divided into an upper layer solution and a lower layer solution, the lower phase being the stationary phase, and the upper phase being the mobile phase. Weigh 200 mg of crude polysaccharide extract, and use mobile phase to prepare 20 ml of sample solution. After filling the entire HS-CCC helical column with the stationary phase, turn on the chromatograph, adjust the rotation speed to 600r / min, then introduce the mobile phase at a flow rate of 1ml / min, and inject the sample after the two phases reach equilibrium; and use a rotation speed of 600r / min , eluted with a mobile phase at a flow rate of 1ml / min, collected an eluent for every 6ml, combined the 26th to 30th eluents, and freeze-dried. The obtained product has a polysaccharide content of 76.7% and a protein content of 18.8%.

Abstract

The invention pertains to the field of extracting active ingredients of natural products and particularly relates to an extracting method and a purifying method of crude phellinus igniarius polysaccharides. The technical problems needed to be solved are to disclose a method for extracting the extract of crude phellinus igniarius polysaccharides and an efficient method for preparing phellinus igniarius polysaccharides through countercurrent chromatography. An ultrasonic extraction is adopted by the invention to extract crude phellinus igniarius polysaccharides from phellinus igniarius fruit bodies; the high-speed countercurrent chromatography is adopted to further purify the crude phellinus igniarius polysaccharides. The extracting method and the purifying method of the invention have high yield of crude phellinus igniarius polysaccharides, and can take up 6 percent of crude drugs; the purity of the further purified phellinus igniarius polysaccharides is greatly improved to be about 75 percent.

Description

technical field [0001] The invention belongs to the field of extracting effective components of natural products, and in particular relates to a method for extracting Phellinus crude polysaccharide and a method for purifying Phellinus polysaccharide. Background technique [0002] Phellinus linteus (Phellinus linteus), parasitic on poplar, willow, birch, oak, pine and other trees, is widely distributed and is a traditional Chinese medicine for oriental people (especially China, Korea and Japan, etc.). In recent years, Japan and South Korea have successively developed it. It is currently an internationally recognized medicinal fungus with very good efficacy in the field of biological anticancer. MeSima) has become a hotspot in the field of medicinal fungi research. It has been confirmed that the efficacy of Phellinus Phellinus mainly comes from polysaccharide from Phellinus linteus, and its pharmacological effects are as follows: [0003] 1. Anti-cancer: As early as 1968, Ja...
