Problems solved by technology

Chinese patent CN1181271 introduces the use of low-pressure water boiling process. Due to the relatively low temperature (55-85°C), the pharmacological activity of polysaccharides is 3-5 times higher than that of conventional water boiling (100-110°C). Ganoderma lucidum is low in triterpene acids

Embodiment 1

[0022] Embodiment 1: Weigh 200g of Ganoderma lucidum flakes, add supercritical CO 2 In the extraction tank, first wet it with 500ml ethyl acetate, and extract statically at 30Mpa, 40°C for 15min. 99.5-99.995% pure CO 2 The flow rate is 120ml / min, continuous dynamic extraction for 0.5 hours to remove fat-soluble impurities. Thereafter, ethyl acetate was used as a polar agent (24ml / min), and the ganoderma triterpene acid was extracted for another 3 hours under the supercritical conditions of 30Mpa and 40°C. As a result, 5.1 g of Ganoderma lucidum triterpene acid extract was obtained in the form of brownish-yellow extract, and the content of Ganoderma lucidum triterpene acid was 32.5%.

[0023] In a high pressure tank (i.e. supercritical CO 2 The extracted raffinate in the extraction tank) is then extracted with 8 times the amount of water at 80°C for 1.5 hours, extracted 3 times successively, concentrated in a three-effect concentration tank at low temperature (below 60°C) un...

Embodiment 2

[0025] Example 2: Weigh 200g of Ganoderma lucidum flakes, first wet it with 500ml ethanol, extract it statically at 35Mpa, 80°C for 15min, and then extract it at 25Mpa, 80°C, CO 2 The flow rate is 120ml / min, continuous dynamic extraction for 0.5 hours to remove fat-soluble impurities. Thereafter, ethanol was used as polar agent (24ml / min), and Ganoderma triterpene acid was extracted for 3 hours under supercritical conditions of 25Mpa and 80°C. As a result, 5.2 g of Ganoderma lucidum triterpene acid extract was obtained, wherein the content of Ganoderma lucidum triterpene acid was 42.5%. The extracted raffinate was then extracted with 8 times the amount of water at 70°C for 1 hour, extracted 3 times successively, and after low-temperature concentration and drying, 10.0 g of Ganoderma lucidum polysaccharide in the form of brownish-yellow extract was obtained, which contained 36% of Ganoderma lucidum polysaccharide .

Embodiment 3

[0026] Example 3: Ganoderma lucidum raw material 200g, the dynamic extraction conditions are 50MPa, 50°C, the polar agent dosage is 18mL / min, the rest is the same as in Example 2, and the result is 6.0g of Ganoderma lucidum triterpene acid extract with a content of 36.0%. Obtaining Ganoderma lucidum polysaccharide Extract 9.6g, content is 34%.

Abstract

The invention is a method of preparing glossy ganoderma triterpenic acid and amylase by glossy ganoderma, crushing the dry glossy ganoderma seeds (water content 5-8%) into particles; or cutting into slices, then putting raw material in a high-pressure extraction kettle, then injecting CO2 and polar agent in the extraction kettle by a supercritical CO2 high-pressure pump and a polar agent pump, respetively, where the extracting pressure of the high-pressure pump is 25-50 MPa, the injection quantity of the polar agent in bulk percent is 10-20%, the temperature is 35-80 deg.C, and the extracting time 2-4 hours, obtaining the extract of glossy ganoderma triterpenic acid; adding water by 8-16 times in the residues, heating to 80-100 deg.C, extracting for 1-2 hours, obtaining the extract of glossy ganoderma amylase. In the products prepared by this invention, the content of glossy ganoderma triterpenic acid is up to 60.2% (by HPLC detection); that of glossy ganoderma amylase 36% (by UV spectral detection).

Description

technical field [0001] The invention relates to a method for preparing ganoderma triterpene acids and ganoderma polysaccharides from ganoderma, in particular to a method for preparing ganoderma triterpene acids and ganoderma polysaccharides from ganoderma using supercritical combination technology. Background technique [0002] Ganoderma lucidum is a traditional Chinese medicine that was once called "the fairy grass". Modern pharmaceutical research shows that it has the functions of anti-aging, anti-inflammation and liver protection, improving human immunity, inhibiting tumors and anti-AIDS (HIV-1). It contains a variety of biologically active substances, the two most important of which are ganoderma triterpene acids and ganoderma polysaccharides. [0003] At present, most of the traditional methods for preparing ganoderma triterpene acids and ganoderma polysaccharides use water boiling or alcohol extraction. Chinese patent CN1181271 introduces the use of low-pressure wate...
