Embodiment 1

[0014] Best Embodiment Example 1: After degreasing, the shell of Xantho sorbifolia is crushed to 5-20 mesh, and 500 ml of solution with ethanol content of 20% and methanol content of 10% is used to soak 50g of X. sorbifolia husk powder and extract at 70°C. After 120 minutes, filter; (2) Boil the filtrate under normal pressure to remove ethanol, water and methanol to about 150 ml, then change to vacuum concentration. After removing impurities by ester extraction, extract three times with 2 times the volume of water-saturated n-butanol, collect the n-butanol phase, and concentrate; Elute with 75% ethanol, and collect part of the eluate; (4) The application of xanthoside in the field of lipid-lowering and weight-loss functional food is: adding xanthoside to rice flour at a ratio of 0.5% (mass ratio) and mixing Stir evenly, can inhibit the activity of pancreatic lipase up to 45%.

Embodiment 2

[0015] Example 2: After degreasing, the shell of X. sorbifolium was crushed to 5-20 mesh, soaked in 1000 ml of a solution with 40% ethanol and 5% methanol, soaked 50 g of X. sorbifolia powder, extracted at 70°C for 240 minutes, and filtered (2) Boil the filtrate under normal pressure to remove ethanol, water and methanol to about 200 milliliters, and then change it to concentration under reduced pressure. The conditions for concentration under reduced pressure are 70°C and 0.1 atmosphere. Concentrated and then freeze-dried; (3) Add Xingroside saponin extract to the column chromatography filler, then elute with 75% ethanol, and collect part of the eluate; (4) Xingguan fruit saponin is used in the field of lipid-lowering and weight-loss The application of Xingguan fruit saponin is: adding sorbiflora saponin into common food in the proportion of 1.1% (mass ratio), mixing and stirring evenly, it can inhibit the activity of pancreatic lipase by 58%.

Abstract

The invention aims to provide a method for preparing saponin from xanthoceras sorbifolia shells with high efficiency, high purity, high yield, short time consumption, simplicity in operation, low production cost and low equipment corrosion and xanthoceras sorbifolia saponin with efficient lipid reducing and weight losing effects. The saponin can be applied in the field of reducing lipid and losing weight, for example, the saponin is added into functional food in a certain ratio, and xanthoceras sorbifolia saponin functional food with a good effect can be obtained. According to the technical scheme, the method comprises the following steps of: extracting the crushed and degreased xanthoceras sorbifolia shells by using a certain quantity of solution, filtering, concentrating, extracting with ethyl acetate so as to remove impurities, extracting with saturated n-butanol, concentrating, filling into a column for chromatography, collecting a part of eluent, and concentrating and freeze-drying the eluent, thus obtaining the xanthoceras sorbifolia saponin. By adding the xanthoceras sorbifolia saponin into the food in a certain ratio, effects of reducing lipid and losing weight can be achieved.

Description

technical field [0001] The invention provides the application of xanthoside in the field of lipid-lowering and weight-loss and a preparation method thereof, and belongs to the field of agricultural product processing technology, functional food and other related fields of lipid-lowering and weight-loss. Background technique [0002] Xanthos sorbifolium belongs to Sapindaceae genus, also known as Asparagus, Asparagus, etc. It is a precious woody tree species unique to my country. Xanthophyllum sorbifolium contains a high amount of saponins, up to 4% by colorimetry. Xanthania saponins belong to oleanane-type saponins, which are commonly found in plants such as Fabaceae, Araliaceae, Umbelliferae, Primulaceae, and Cucurbitaceae. Saponins are rich in resources and easy to extract. They are widely found in stems, leaves, flowers, fruits and other organs of plants. They are a group of substances with different structures and properties, and belong to plant secondary metabolites. ...
