Embodiment 1

[0042] Embodiment 1, the weight loss purposes of bean taro flower polysaccharide, such as Figure 1-Figure 5 It has been shown that taro flower polysaccharide has a significant weight-loss and fat-lowering effect.

[0043] The specific preparation steps of taro flower polysaccharide are as follows:

[0044] (1) Weigh 100g of taro flowers, add 500mL of distilled water according to the ratio of material to liquid: 1g: 5ml, inactivate the enzyme in a water bath at 90°C for 80min, then beat the pulp, centrifuge at 4000r / min for 15min, take the supernatant and collect the filtrate .

[0045] (2), replace the taro flower in step (1) with the filter residue obtained by centrifugation in step (1), repeat the extraction 2 times, combine the filtrate three times, and concentrate by rotary evaporation to obtain a concentrated solution (concentrated by rotary evaporation to 1 / 5 of the original volume) .

[0046] (3) Add pure ethanol to the concentrated solution obtained in step (2) und...

Embodiment 2

[0056] Embodiment 2, the effect of taro flower polysaccharide on fat, liver and other organ indexes of obese mice;

[0057] Fasted for 24 hours after 12 weeks of intragastric administration in Example 1, weighed the body weight, and killed the mice by cervical dislocation after blood was taken from the orbits. The fat around the kidneys and epididymis was taken, and the heart, liver, spleen, and kidney were quickly removed. , brown fat and other tissues and record the weight, the specific data are shown in Table 1.

[0058] Table 1 The effect of taro flower polysaccharide intervention on the organ index of mice

[0059]

[0060] According to Table 1, it can be seen that the intervention of taro flower polysaccharide can alleviate the decline of liver index in obese mice induced by high-fat diet, and can significantly reduce the peritesticular fat and perirenal fat index in obese mice. Compared with the high-fat control group, soybean Taro flower polysaccharide intervention...

Embodiment 3

[0061] Embodiment 3, the influence of taro flower polysaccharide on obese mice serum triglyceride (TG), total cholesterol (TC), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) content;

[0062] The mice after 12 weeks of intragastric administration in Example 1 were fasted for 24 hours, and the mice were killed by cervical dislocation after blood was taken from the eye sockets. The blood samples were centrifuged at 1500 rpm for 15 minutes, and the serum was taken and preserved, and the glycerol in the serum was analyzed by a Toshiba automatic biochemical analyzer. The contents of triester and total cholesterol were determined, and the specific data are shown in Table 2.

[0063] Table 2 Effects of taro flower polysaccharide intervention on serum indicators in mice

[0064]

[0065] According to Table 2, it can be seen that high-dose taro flower polysaccharide intervention can reduce the total cholesterol content in serum of obese mice induced by high-fat...

Abstract

The invention discloses application of taro flower polysaccharide to weight losing and provides a new resource for developing a natural weight-losing product in the fields of medicine, food science and the like. High-fat diet induced obesity mouse test evaluation proves that the taro flower polysaccharide can obviously reduce the weight of the obesity mouse and reduce the content of triglyceride and total cholesterol in serum and liver, and has comprehensive and remarkable effect. Therefore, the taro flower polysaccharide is applied to preparation of weight-losing food or medicines so as to treat and prevent obesity and related chronic diseases.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a weight-loss application of taro flower polysaccharide. Background technique [0002] Apios americana Medikus is a perennial leguminous plant (Papilionaceae subfamily) native to the eastern part of North America from Canada to the southern part of Florida. Its edible part is the underground tuber, and its protein content is higher than that of other plant tubers. It is a crop with both nutrition and economic value, so it is often used as a staple food by Indians. Bean taro has been successfully introduced in China since 2009, and has been gradually promoted and planted in Fuyang, Jinhua, Longyou, Wenzhou and other places. Studies have shown that different parts of taro (flowers, vines, leaves, tubers) are rich in free amino acids, soluble proteins, polysaccharides, saponins, flavonoids, isoflavones, vitamin C, vitamin E and minerals. Among them, taro flower has the highest vitamin C co...
