Example 1: capsule preparation
Taking 50 parts by weight of cistanche extract, 180 parts by weight of red sage extract, 30 parts by weight of ginkgo leaf extract and 70 parts by weight of alpinia oxyphylla extract, adding an appropriate amount of auxiliary materials such as starch, povidone and magnesium stearate, and preparing the mixture into capsule particles according to a conventional method in the field.
Example 2: evaluation test for improving memory function of human body by aid of capsules
1 materials and methods
1.1 sample: the capsule and the placebo of the invention have the specification of 0.35 g/granule and the recommended dosage of human body of 1.4 g/person/day. The administration method comprises the following steps: orally taken 2 times a day, 2 granules each time.
1.2 principle of selecting subjects
Selecting a voluntary subject from a population in which the influence factors are substantially the same in all aspects in the comparative set; the culture degree is basically consistent; if the corresponding scale belongs to the same age group, correcting the scale if the corresponding scale is not in the same age group; similar testers were not accepted; excluding those taking items related to the function under test for a short period of time, and having an influence on the result.
1.3 test methods
According to the human body test food test procedure of the technical specification of health food inspection and evaluation (2003 edition), the memory quotient of the test subject is measured according to the test requirement by adopting a clinical memory scale.
1.4 test Meter
The "clinical memory scale" revised in the national academy of sciences psychological institute 1996 was adopted.
1.5 test food design and grouping
The health analysis and detection center of Nanjing medical university and the 105 th Hospital of the Chinese people's liberation army jointly carry out human body test food test, and the people with the ages of 18-65 years and good physical health condition are selected to be subjected to volunteer test to ensure matching. Subjects underwent informed consent. Two control designs, self and inter-group, were used. The test feeding group and the control group are randomly divided according to the Memory Quotient (MQ), and main factors such as age, sex and the like affecting the result are considered as much as possible to carry out balance test so as to ensure comparability among the groups. The complete test diet and inclusion statistics were 102, with test diet group 51 and control group 51.
1.6 administration dosage and time
The test group took the test sample and the control group took the placebo. The administration method comprises the following steps: orally taken 2 times a day, 2 granules each time. The test feeding observation time is 30 days.
1.7 Main instruments
Full-automatic biochemical analyzer (a 25 biosystems spain); full-automatic blood analyzer (BC-3000 PLus home-made, michael); urine chemistry analyzer (Uritest-300 Guilin); ultrasonic B machine (RH-3200, shanghai); x-ray fluoroscopy (Imax-1500 z Germany); electrocardiograph (AIKD-B-12 Beijing).
1.8 observations index
1.8.1 safety index
1.8.1.1 general status: mental, sleep, diet, bowel movement, heart rate, blood pressure, etc.
1.8.1.2 blood and urine routine examination: blood routine programs include white blood cells, red blood cells, hemoglobin, and platelets.
1.8.1.3 biochemical blood examination: the examination items include serum total protein, albumin, glutamic pyruvic transaminase, urea, creatinine, cholesterol, triglyceride, and blood sugar.
1.8.1.4 chest radiography, electrocardiogram and abdomen B-ultrasound examination: only once before the start of the test.
1.8.2 efficacy index
Clinical memory scales were used. The method comprises pointing to a memory score, associating the memory score, freely recalling the memory score by images, recongning the memory score by nonsensical images, and associating the memory score by portrait characteristics. Testing the original score with each tested score, adding the score to obtain a total score, and checking the memory quotient with the total score.
1.9 data statistics
The parallel comparison between groups adopts t test of the average value of two samples, the self comparison data adopts paired t test, and when the variance is uneven, data conversion is carried out or t' test, rank sum test are used. The effective rate and the total effective rate are checked by adopting the X2 test. The total number of cases of the four-grid table is smaller than 40, or the total number of cases is equal to or larger than 40, but when the theoretical number is equal to or smaller than 1, the exact probability method is adopted instead.
1.10 result determination
On the premise that two groups of memory quotient are balanced before the test, the memory quotient of the test food group after the test food is higher than that of the control group, the difference is significant, and meanwhile, the memory quotient of the test food group after the test is higher than that of the test food group before the test, the difference is significant, so that the tested sample can be judged to have the function of assisting in improving the memory function.
