Embodiment 1
[0038] Example 1 Relationship between GABA in mulberry leaves, celery seeds, and hawthorn and its ACE inhibition rate
[0039] The water extract of mulberry leaf fine powder was obtained according to the above method, and the concentration of GABA was detected therein, and the inhibition rate of ACE was detected with the water extract of mulberry leaf fine powder containing different GABA concentrations. The results are shown in Table 1.
[0040]
[0041] Calculate the regression equation according to Table 1, the equation is: y=11.4x+79.76, where: x represents the concentration of GABA; y represents the ACE inhibition rate.
[0042] Through the significance test, the following results were obtained (Table 2)
[0043]
[0044] It can be concluded from Table 2 that the regression equation y = 11.4x + 79.76, R 2 =0.8486, P<0.05 is a significant level, indicating that there is a linear relationship between the ACE inhibition rate of mulberry leaf extract and the GABA concent...
Embodiment 2
[0048] Example 2 Determination of the Optimal Combination Ratio of Mulberry Leaf, Celery Seed and Hawthorn
[0049] According to the regression equation established in the single factor experiment, the concentration of each material with an inhibition rate of 80%, 85%, and 90% was selected to conduct an orthogonal experiment according to the volume ratio of 1:1:1, and the GABA concentration was calculated as follows:
[0050] According to the regression equation of Example 1, the three levels of the mulberry leaf powder factor are 1, 2, and 3, and the corresponding GABA concentrations in the extract are respectively 0.11 mg / mL, 0.47 mg / mL, and 0.93 mg / mL.
[0051] The three levels of celery seed factor are 1, 2, and 3, and the corresponding GABA concentrations in the extract are 0.16 mg / mL, 0.31 mg / mL, and 0.46 mg / mL, respectively.
[0052] The three levels of the hawthorn factor are 1, 2, and 3, and the corresponding GABA concentrations in the extract are 0.02 mg / mL, 0.04 mg / ...
