Below by the radicals scavenging effect of description of test mulberries extract of the present invention.
DPPH(1,1- diphenyl -2- trinitrophenyl-hydrazines)It is a kind of organic free radical of stabilization, its ethanol solution is in purple, There is strong absorption at wavelength 517nm.In the presence of having free radical scavenger, the lone pair electrons of DPPH are paired, so that its Fade, fading extent receives electronics in quantitative relationship with it, therefore available colorimetric method carries out quantitative analysis.Below with DPPH for The radicals scavenging effect of bright mulberries extract.
Mulberries extract prepared by mulberries extract prepared by embodiment 1, embodiment 2, VC distilled water are configured to molten Liquid, concentration is:10mg/L、20mg/L、30mg/L、40mg/L、50mg/L;DPPH is configured to 2 × 10 using absolute ethyl alcohol- 4The solution of mol/L;The sample solution to be measured and DPPH solution of same volume are taken, is well mixed, 20min, Yu Bo are placed at room temperature Mensuration absorbance A at 517nm longi;The sample solution to be measured and absolute ethyl alcohol of same volume are taken, is well mixed, placed at room temperature 20min, the mensuration absorbance A at wavelength 517nmj;The DPPH solution and absolute ethyl alcohol of same volume are taken, is well mixed, room temperature Lower placement 20min, the mensuration absorbance A at wavelength 517nmc;Calculate the free radical scavenging activity of each testing sample, clearance rate=[1- (Ai-Aj)/Ac]×100%。
With sample solution concentration to be measured as abscissa, clearance rate is that ordinate draws curve, according to the linear regression of curve Equation, calculates the mulberries extract of the preparation of embodiment 1, the semi-inhibit of mulberries extract removing free radical prepared by embodiment 2 dense Degree(IC50).
Experimental result:The IC of mulberries extract prepared by embodiment 150It is 7.80mg/L, mulberries prepared by embodiment 2 are extracted The IC of thing50It is 7.82mg/L.According to experimental result, it can be seen that mulberries extract prepared by embodiment 1 and embodiment 2 has strong Radical scavenging activity.Moved towards according to curve, when concentration is 40-50mg/L, curve tends to be steady and has a downtrend, When concentration be 45mg/L when, embodiment 1 prepare mulberries extract, embodiment 2 prepare mulberries extract, VC free radical it is clear Except rate reaches maximum, respectively 98%, 97.5%, 85%, according to the above results, it can be seen that prepared by embodiment 1 and embodiment 2 The free radical maximal clearance of mulberries extract is big compared with VC, i.e., the mulberries extract that prepared by embodiment 1 and embodiment 2 substantially can Remove all of free radical.
IC of the mulberries anthocyanidin to radical scavenging activity is calculated using above-mentioned experimental technique50, by calculating, IC50It is worth and is 12.33mg/L.According to result of calculation, it can be seen that mulberries extract prepared by embodiment 1 or embodiment 2 has compared with mulberries anthocyanidin There is more preferable radical scavenging activity.
In sum, mulberries extract of the invention can be purged to free radical, and it is pure natural substance, to human body Have no side effect.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair The equivalent transformation that bright description is made, or other related technical fields are directly or indirectly used in, similarly it is included in In scope of patent protection of the invention.
