Example 6 alpha-glucosidase inhibitory Activity
The extracts in this example were prepared as described in example 1.
Measurement of α -glucosidase inhibitory activity:
the influence of the garlic extract and the allium mongolicum regel extract on the activity of the alpha-glucosidase is determined by adopting a 4-nitrophenol-alpha-D-glucopyranoside (PNPG) colorimetric method. Sequentially adding 50uL of extracts (20mg/mL) with different ratios and 100uL of alpha-glucosaccharase solution (5mg/mL) into a 96-well plate, uniformly mixing, and reacting at 25 ℃ for 10 min; adding 50uLPNPG solution (5mmol/L), and reacting at 37 deg.C for 10 min; finally 50uLNa is added2CO3And (3) mixing the solution (0.67mol/L), measuring the absorbance at the wavelength of 405nm, and calculating the inhibition rate. Acarbose was used as a positive control in this assay to add 100uL of alpha-glucosidase solution (5mg/mL), 50uLPNPG solution (5mmol/L) and 50uLNa to 50uL of phosphate buffer (pH6.8)2CO3The solution (0.67mol/L) served as a control group; to 50uL of phosphate buffer (pH6.8) were added 100uL of an α -glucosidase solution (5mg/mL), 50uL of phosphate buffer and 50uLNa2CO3Solution (0.67mol/L) was used as control blank; adding 50uL of Bulbus Allii extract and Allium mongolicum regelTo the extract (20mg/mL) were added 100uL of an α -glucosidase solution (5mg/mL), 50uL of phosphate buffer and 50uLNa2CO3The solution (0.67mol/L) served as a sample blank. The inhibition rates of the garlic extract and the allium mongolicum regel extract on alpha-glucosidase in different proportions are measured, and the hypoglycemic activity of the allium mongolicum regel extract is evaluated, and the results are shown in table 1.

TABLE 1 inhibition of alpha-glucosidase by different extracts
Figure BDA0002585961740000052
Figure BDA0002585961740000061
The alpha-glucosidase inhibitor does not stimulate the secretion of insulin, and the single use of the medicine does not usually cause hypoglycemia, so that the alpha-glucosidase inhibitor can help reduce the fluctuation of blood sugar, can obviously reduce the probability of cardiovascular diseases of diabetics, and has the most obvious effect of improving myocardial infarction. Is one of the few oral hypoglycemic drugs which can interfere with impaired glucose tolerance. The alpha-glucosidase inhibitor has been reported to have definite curative effect on diabetes, and also has certain curative effect on obesity, chronic hepatitis B, AIDS and tumor.
Acarbose is an alpha-glucosidase inhibitor, which can inhibit the activity of various alpha-glucosidase such as maltase, isomaltase, glucoamylase and sucrase, so that the rate of starch decomposition into oligosaccharides such as maltose (disaccharide), maltotriose and dextrin (oligosaccharide) and further glucose decomposition is reduced, and the rate of sucrose decomposition into glucose and fructose is reduced, thereby causing the absorption of glucose in intestinal tract to be slowed down, relieving postprandial hyperglycemia and achieving the effect of reducing blood sugar. Can reduce fasting blood glucose and glycosylated hemoglobin after long-term administration.
As can be seen from the data in Table 1, the garlic alcohol extract, the garlic water extract, the allium mongolicum regel alcohol extract and the allium mongolicum regel water extract all have the inhibition effect on alpha-glucosaccharase, but the inhibition effect is weaker; after the four components are combined, the inhibition effect on alpha-glucosaccharase is stronger than that of any single extract under the same dosage, which shows that the garlic alcohol extract, the garlic water extract, the allium mongolicum regel alcohol extract and the allium mongolicum regel water extract are combined to realize synergistic interaction, so that the inhibition activity of the extracts is improved, wherein the garlic alcohol extract: garlic water extract: the allium mongolicum regel alcohol extract: the allium mongolicum regel aqueous extract has the highest inhibitory activity when the allium mongolicum regel aqueous extract is 5.0:1.0:1.7:0.5, and can be used for preparing products for preventing and/or treating diseases taking alpha-glucosaccharase as a target. The garlic and the allium mongolicum regel are both daily usable raw materials, and the garlic and the allium mongolicum regel are natural food extracts and are high in safety.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
