Abstract

The invention relates to the field of plant extraction, in particular to an extraction method of basil seed crude polysaccharides. According to the extraction method, basil seeds are beaten into pulp,by means of combination of high-temperature ultrasonic extraction and enzyme extraction, plant cell walls can be damaged, release of polysaccharides in cells is facilitated, and dissolution rate of the polysaccharides is increased. By means of combination of high-temperature ultrasonic extraction and enzyme extraction, the plant cell walls can be damaged, release of the polysaccharides in the cells is facilitated, and the dissolution rate of the polysaccharides is increased.

Description

Technical field [0001] The invention relates to the field of plant extraction, in particular to a method for extracting crude polysaccharides from Lanxiangzi. Background technique [0002] Lanxiangzi, also known as basil, is the fruit of basil, a plant of the Lamiaceae. The dried nutlets are ovoid in shape, about 2 mm long, with traces of the stalk at the base; the surface is gray-brown to black, with a slight luster, and fine dots can be seen under an enlarged lens. The texture is hard, the cross section is triangular, the cotyledons are thick, milky white, and rich in oil. It is weak in breath, light in taste, and smooth in the mouth; after soaking in water and swelling, there is a layer of white mucus on the surface. The white thing wrapped around the seeds is a substance called "mucopolysaccharide". The fruit mucilage contains 9.2% pentose, 70.3% hexose, 7.3% uronic acid, 25.4% free lipid, and 10.3% combined lipid. The mucopolysaccharide is hydrolyzed to produce D-galactu...
