The antioxidation activity in vitro of sedge extract provided by the present invention is evaluated and experimental result:
1. the measurement of sedge extract removing hydroxyl radical free radical ability
It with reference to Fenton method, takes 0.75mmol/L Phen 1mL in test tube, sequentially adds PBS (pH 7.4) 2mL, Distilled water 1mL after mixing well, is added 0.75mmol/L ferrous sulfate 1mL, mixes, and adding mass fraction is 0.12% H2O2 1mL, 37 DEG C of water-bath 60min measure its absorbance A at 536nmpValue;H is replaced with distilled water2O2, measure its absorbance AbValue; It takes and replaces distilled water 1mL with ethyl alcohol dilution 1,0.2,0.1,0.07, the sedge alcohol extract solution of 0.05mg/mL respectively, measurement Its absorbance AsValue.Separately take the sedge water extract (crow i.e. in embodiment 2 of 0.07,0.05,0.04,0.03,0.02mg/mL Careless extract being drawn, similarly hereinafter) solution replaces distilled water 1mL, measure another set absorbance AsValue.0.1,0.2,0.5,0.7,1mg/ ML vitamin C (VC) is positive control.Sample is calculated to the clearance rate of hydroxyl radical free radical, formula is as follows:
Clearance rate (%)=(As-Ap)/(Ab-Ap) × 100%
As shown in Figure 1, within the scope of 0.02~1mg/mL mass concentration, sedge alcohol extract (is replaced with same volume ethyl alcohol Water extracts to obtain sedge alcohol extract, similarly hereinafter) and water extract be in dose-effect relationship to the Scavenging activity of hydroxyl radical free radical, with mass concentration Increase, clearance rate increases.Wherein, sedge water extract removing hydroxyl radical free radical ability is better than alcohol extract: when water extract concentration reaches When to 0.07mg/mL, clearance rate is maximum, is 91.85 ℅;And when alcohol extract concentration reaches 1mg/mL, maximal clearance only has 84.12℅.The two is superior to VC to the Scavenging activity of hydroxyl radical free radical.
2. the measurement of sedge extract scavenging ability of DPPH free radical
The sedge alcohol extract solution 2mL of 2,1,0.5,0.33,0.25mg/mL is taken, isometric concentration, which is added, is The DPPH solution (being prepared with dehydrated alcohol) of 0.1mmol/L, is protected from light 30min at room temperature, measures at 517nm after mixing Absorbance Ai;And it returns to zero using 4mL dehydrated alcohol and distilled water (the two is respectively 2mL) as blank.Blank control group is 2mL sample Product liquid adds 2mL dehydrated alcohol, and the light absorption value at 517nm is Aj, be arranged blank control group the purpose of be for Polysaccharide removing The light absorption value of sample itself.Model control group is that 2mL DPPH solution adds 2mL dehydrated alcohol, the light absorption value at 517nm For A0.Changing mass concentration into respectively is 2, the sedge water extract solution of 1,0.2,0.1,0.067mg/mL, 0.0033, 0.0065, the VC of 0.0125,0.025,0.05mg/mL, repeats the above process.Sample is calculated to the clearance rate of DPPH free radical, Formula is as follows:
Clearance rate (%)=[1- (Ai-Aj)/Ao] × 100%
As shown in Figure 2, within the scope of 0.067~2mg/mL mass concentration, sedge alcohol extract and water extract to DPPH from Dose-effect relationship is presented by the Scavenging activity of base, is increased with mass concentration, power enhancing is removed.When mass concentration reaches 2mg/mL, water The clearance rate of extract is 99.7 ℅, and alcohol extract is 62.8 ℅, shows that the ability of sedge water extract removing DPPH free radical is better than Alcohol extract, but the two is weaker than VC.
3. the measurement of sedge extract removing ABTS free radical ability
5mL 7mmoL/L ABTS and 88 μ L 140mmoL/L potassium peroxydisulfates are mixed, stood under the conditions of room temperature is protected from light Night (12-16h) forms ABTS free radical stock solution, is then diluted to ABTS working solution with 1:50 ratio with distilled water, makes 30 DEG C, absorbance is 0.702 at 734nm wavelength.
Precision pipettes the sedge alcohol extracting of different quality concentration (2,0.33,0.2,0.1,0.067,0.05mg/mL) respectively Object and each 2.0mL of water extract solution example are separately added into ABTS measurement liquid 2.0mL, accurately shake 10s, stand in test tube After 6min, A is measured at 734nm.Dehydrated alcohol 2.0mL is pipetted in test tube simultaneously, is handled in the same way, is measured Ao。 Using 1,2,2.5,3mg/mL VC solution as positive control.Replication 3 times, calculate clearance rate.
Clearance rate (%)=(Ao-ASample)/Ao× 100%
From the figure 3, it may be seen that within the scope of 0.05~2mg/mL mass concentration, removing of the sedge alcohol extract to ABTS free radical Power first increases and then decreases, when concentration reaches 0.33mg/mL, clearance rate is maximum, is 79.36 ℅;Water extract clearance rate is but with dense Degree increases and reduces, and when concentration is 0.05mg/mL, clearance rate is maximum, is 80.83 ℅.It is comprehensively compared, sedge water extract pair The removing power of ABTS free radical is greater than alcohol extract.Meanwhile the two removes power and is better than VC, when concentration reaches 3mg/mL, VC's Clearance rate is 60.21 ℅.
4. the measurement of sedge extract removing ultra-oxygen anion free radical ability
50mmol/L Tris-HCl buffer (pH 8.2, EDTA-2Na containing 2mmol/L) 4.5mL is taken, is separately added into not Sedge alcohol extract, water extract and each 1mL of VC solution of homogenous quantities concentration (0.01,0.02,0.03,0.05,0.07mg/mL), Pyrogallol (with the preparation of 10mmol/L hydrochloric acid) 0.2mL, pours into cuvette, immediately with isometric 10mmol/L hydrochloric acid generation after mixing It is blank zeroing for pyrogallol solution, measures an absorbance A value every 30s at 325 nm wavelength, calculates in the range of linearity A value changes with time value, and control group replaces sample solution with isometric deionized water.It calculates to ultra-oxygen anion free radical Clearance rate.
Clearance rate (%)=(V1-V2)/V1× 100%
In formula, V1For the autoxidation rate of control tube pyrogallol;V2For the autoxidation rate of sample cell pyrogallol.
As shown in Figure 4, when mass concentration is 0.01~0.07mg/mL, sedge alcohol extract and water extract are to super oxygen yin The removing power of ion is in dose-effect relationship.Alcohol extract removes power and increases with concentration and enhance, and it is 63.79 ℅ that maximum, which removes power,;Water mentions Object is removed power and is then increased with concentration, and presentation first enhances, the trend weakened afterwards, and maximal clearance is 78.16 ℅, corresponding mass concentration For 0.05mg/mL.The above result shows that sedge water extract is better than alcohol extract to the removing power of superoxide anion, it is suitable with VC (maximal clearance is 78.74 ℅).
The identification of aqueous extract chemical component and active constituent content measuring:
Sedge crushes about 0.5cm or so, is put into round-bottomed flask and extracts, and is mentioned with water (1:10, w:v) as 90 DEG C of solvent Take 2~3h, extract 2 times, merging filtrate, natural filtration, filtrate is concentrated to the 1/2 of stoste volume, carry out chemical component identification and Assay.
