MDL	MFCD28964039
Physical and Chemical Properties	White crystalline powder, soluble in methanol, ethanol, DMSO and other organic solvents, from Scrophulariaceae plant Rehmannia glutinosa.

Application	mannotriose is a natural functional oligosaccharide, can be a potent proliferation of human intestinal beneficial bacteria (Bifidobacteria and lactic acid bacteria, etc.), has a good physiological function.
preparation	a method for preparing high-purity mannotriose from fresh rehmannia glutinosa, consisting of the following steps: (1) high-temperature processing of fresh rehmannia glutinosa: take 25.0g of fresh rehmannia glutinosa collected, discard the mouldy parts, wash them, cut them into sections with a thickness of 3cm, and heat them to 90 ℃ for 6H; (2) preparation of Mannan trisaccharide sample solution: add the processed product of fresh rehmannia glutinosa obtained in step (1) to water at 70 ℃ for 0.5h at a ratio of 1:2, the residue was further leached once according to the above process, and the extracts were combined and concentrated to 60 in vacuo. The sugar solution of Brix, I .e., a Mannan trisaccharide-like solution, is obtained. (3) alcohol precipitation to obtain Mannan trisaccharide-like liquid alcohol precipitation part: add ethanol to Mannan trisaccharide-like liquid according to the volume ratio of 1:2, at a temperature of 80 deg C for 30min, Natural cooling and allowing to stand for 24h; Alcohol precipitation of Mannan trisaccharide-like liquid; (4) removal of impurities, decolorization and concentration to obtain Mannan trisaccharide-like liquid: the alcohol precipitation Mannan trisaccharide sample solution obtained in step 3 is diluted 10 times with water, and 0.5% activated carbon or macroporous adsorption resin (the ratio of the weight of the sample solution to the volume of the resin is 450g/L) is used. After decolorization, the sample solution was concentrated to 60 at 60 °c after filtration. Brix; (5) gel LH20 column chromatography to obtain Mannan trisaccharide: dilute the Mannan trisaccharide sample solution to 10. Brix, Elution by gel LH20 column chromatography with 25% ethanol, combining fractions containing mannotriose by TLC, concentrating or freeze-drying to give mannotriose, concentrating and drying to give mannotriose 1.1g, the purity was 98.5% and the total yield was 4.4%.
biological activity	mannotriose is the main carbohydrate of sesame seeds (Lamium elephant, Labiatae).
uses	mannotriose has pharmacological activities such as promoting the proliferation of hematopoietic cells, improving immunity, lowering blood sugar, and anti-tumor.
