Illustrate beneficial effects of the present invention below by way of test example.
Test example 1, golden flower barberry extracts improve the research of mouse memory power
(1) experimental method
It selects the male mouse of kunming mouse that weight is 20 ± 2g to carry out Jumping test, water maze laboratory, and measures mouse
MDA contents in serum and T-SOD vigor.Mouse is raised by weight average grouping.According to gavage condition, will remember again
Existing deficiency model mouse is divided into 5 groups:The root of golden flower barberries, each one group of the high, medium and low dosage of stem, leaf extract, stem n-butanol
Segment group, root n-butanol segment group, it is another to set normal mouse blank group and each 1 group of model group, every group of 8 mouse.Extract
High, medium and low dose concentration be set to 100mg/mL, 50mg/mL, 25mg/mL, root, stem n-butanol segment concentration (w/
Ml it is) 2.1%, 1.64%, continuous processing 27 days.
Ensure that animal in 23 ± 2 DEG C of temperature, free water and feed, controls illumination/dark 12h and follow daily during raising
Ring, 8 points of stopping illumination of night, starts gloss at 8 points between morning.Before experiment starts, Animal adaptability feeds 3d.When first day gavage,
It is weighed, is weighed every three days later primary, nominal weighs 10 times for the first time.
Jumping test:Experimental provision is a rectangle reflective box, is divided between 2, and it is 0.5cm copper grid that bottom surface, which is aided with spacing, often
Between left or right angle place the insulating stand that a height and diameter are 4.5cm.It is formal to measure first 1 day of experiment, after intragastric administration on mice
Mouse is put into electroporation chamber by 30min, and shocked by electricity trained 5min with 100uA electric currents, and mouse is made to generate electric shock memory.It rejects to electric shock
Insensitive mouse is stimulated, carries out formal determination experiment after r for 24 hours, after mouse last time gavage 10min, then gavage is a certain amount of
30% ethyl alcohol (according to mouse weight, ethyl alcohol gavage volume converts by 0.1ml/g), form memory and reproduce deficiency model mouse.
Animal is placed on diving tower after 30min, record mouse jumps off every in the time (incubation period) and 5min of diving tower for the first time
Mouse is total (errors number) by the number to shock by electricity.
Water maze laboratory:Experimental provision is an a diameter of 130cm, the round pool of deep 40cm, artificially by pond point
It for four quadrants and marks, platform fixed placement is central in one of quadrant, and in pond plus water is added to beyond platform 1-
2cm high, water temperature are controlled at 23 ± 2 DEG C.Formal test a few days ago by mouse head along pool wall into the water, make every by permanent order
Mouse enters water from 4 quadrants, measure animal swim in labyrinth total distance, where platform quadrant (target quadrant) time,
The number of swimming average speed and spanning platform, the time average that animal finds platform are incubation period, and each quadrant is dived
Volt phase average value is incubation period on the same day, using the 4th day data as the final result.
Animal is a few days ago put into progress adaptability swimming in water maze by formal test, rejects the individual that do not swim, formally
Experiment 5 days in total, first 4 days are orientation navigation experiment.1h is in addition to blank group injecting normal saline after first day gavage, other each groups
Animal causes acquired dysmnesia model with 0.1ml/10g weight conversion volume intraperitoneal injection hyoscine (3mg/kg).
Mouse is put into free swimming in water maze after 20min, platform the time it takes is found in 60S and is denoted as incubation period, in platform
Stop 5S after, animal is taken out, if animal does not find platform in 60S, by artificially guide animal swim to platform and allow it
Platform stops 5S, is denoted as incubation period 60S;Record mouse swimming total distance, incubation period, target quadrant time percentage after experiment four days
Than and average speed;5th day for space exploration test, space exploration test when platform is removed, allow animal from original platform as
The quadrant on limit opposite enters water, and record animal enters the number of original platform quadrant time and spanning platform.
(2) statistical analysis
Variance analysis is carried out with SPSS18.0 statistical softwares, it is aobvious to indicate that difference has with P < 0.01 for comparison among groups LSD methods
Work property, result data is indicated with means ± std.
(3) experimental result
It will be seen from figure 1 that experimental group with normally group mouse compared with, after gavage 1d, 10d, 19d, 30d,
Each group the weight of animals is not significantly different (P > 0.05), illustrates that golden flower barberries extract influences mouse weight without obvious.
Figure it is seen that experimental group is compared with model group, incubation period obviously increases, and errors number significantly reduces, to surveying
Data it is for statistical analysis obtain experimental group and model group difference extremely significantly (P < 0.01), not with normal group contrast difference
Significantly (P > 0.05).
From figure 3, it can be seen that compared with normally group total distance, model group animal does not have difference;With the target normally organized as
Limit percentage of time equal indifference in addition to model group;Compared with normally group incubation period, model group there were significant differences (P<0.05), root
Extract middle dose group, leaf extract are high, middle dose group has notable or pole significant difference, other group of indifference;It is flat with normal group
Equal speed compares, model group indifference.Compared with model group total distance, the equal no significant difference of each group;With model group target quadrant
Percentage of time compares, and in addition to stem extraction low dose group, other groups have notable or pole significant difference;With model group incubation period
Compare, all dosage groups of root extract low dose group, leaf extract, root n-butanol segment group and stem n-butanol segment group indifference
Different, other groups have notable or pole significant difference;Compared with model group average speed, indifference is normally organized.
From fig. 4, it can be seen that compared with model group animal, in addition to the height of stem extraction, middle dose group and stem n-butanol piece
Section group is outer, and remaining Group Animals spanning platform number dramatically increases (P≤0.05);With model group animal when target quadrant stops
Between compare, the difference of all groups of target quadrant time percentages is extremely significantly (P<0.01);Compared with normally group animal, model
Group spanning platform number is reduced, and there were significant differences (P≤0.05), and target quadrant time percentage is reduced, and has pole significant difference (P<
0.01), experimental group and normal group compare, except stem extraction high dose group traversing times have significant decrease (P≤0.05), other groups
Compared with normal group, the equal indifference of two indices (P > 0.05).
To sum up, golden flower barberries ethanol extract and n-butanol extract make moderate progress to the memory capability of mouse, to note
The improvement result for recalling Disorder Model mouse is apparent.
