Problems solved by technology

For example, the trichosanthin content in Trichosanthes trichosanthes is relatively low, making the price of pure trichosanthin very expensive
When extracting and preparing single components such as trichosanthin and polysaccharides, other bioactive components in trichosanthin are lost in vain. This extraction method not only leads to higher extraction costs, but also wastes trichosanthum resources. Related reports on comprehensive extraction of bioactive components
In addition, the currently extracted trichosanthes polysaccharides are mainly concentrated in water-soluble polysaccharides, and no research on the extraction and function of alkaline polysaccharides has been retrieved.

Abstract

The invention discloses a method for comprehensively extracting diverse bioactive ingredients from radix trichosanthis. The method comprises the steps: firstly, adding ethanol into the radix trichosanthis, carrying out ultrasonic shaking, heating for extracting, carrying out suction filtration on an extract, and concentrating and drying a filtrate, so as to obtain an alcohol-soluble substance; extracting remnant filtrated residues, centrifuging an extract, treating a supernatant, and then, carrying out evaporative concentration and drying, so as to obtain water-soluble crude polysaccharides; adding a sodium hydroxide solution into remnant precipitates, carrying out heated extraction, centrifuging an extract, treating an obtained supernatant, so as to obtain precipitated alkali-soluble polysaccharides, and washing and drying, so as to obtain alkali-soluble crude polysaccharides; then, extracting radix trichosanthis protein from remnant precipitates, and then, further extracting radix trichosanthis agglutinin from remnant precipitates; finally, washing and baking remnant precipitates, thereby obtaining radix trichosanthis starch. By using the method, a variety of effective bioactive ingredients, namely the alcohol-soluble substance, the water-soluble polysaccharides, the alkali-soluble polysaccharides, the protein, the agglutinin and the starch, can be comprehensively extracted from the radix trichosanthis, so that radix trichosanthis resources are utilized to a greater extent, and then the current economic sustainable development is met.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from trichosanthemi, in particular to a method for comprehensively extracting various bioactive ingredients from trichosanthemi. Background technique [0002] Trichosanthes contains a variety of biologically active components, such as trichosanthin, polysaccharides, saponins, lectins, etc. Because the trichosanthin protein has the effects of inducing labor, anti-tumor, anti-virus and anti-HIV; the trichosanthin polysaccharide has activities such as lowering blood sugar and improving immunity. Therefore, at present, there are many studies on the two, and the development and utilization are relatively in-depth, while there are few studies on other bioactive components in trichosanthemi. Existing extraction methods of trichosanthin bioactive substances are mainly based on a single component, such as trichosanthin protein, trichosanthin polysaccharide and trichosanthin lectin. For exampl...
