The testing method comprises the following steps:
DPPH radical scavenging experiments: preparing DPPH liquid: dissolving 1mg DPPH in small amount of absolute ethanol, adding distilled water to 1L, keeping in dark, adding a certain amount of substance to be measured into 2.5mL of 50 μg ∈ -
In mL of DPPH absolute ethanol solution, the absorbance of the solution was measured at 515nm after being left at room temperature for 30 min. The scavenging effect was calculated from the following formula:
S(%)=[A0-(A-A1)]×100%/A0

5 Alpha-reductase inhibition assay: 5α -reductase is a membrane protein that localizes on the microsomes of target cells and plays an important role in the development of androgenic alopecia. After androgen binding to the receptor, complex enzymatic reactions occur, indirectly altering hair growth processes. There are 3 isozymes for 5α -reductase, i.e., types I, II, III. Type i 5 alpha-reductase is present in skin tissues such as sebaceous glands, sweat glands, papilla cells, fibroblasts, epidermal keratinocytes, hair follicle keratinocytes, etc. And type II 5 alpha-reductase is mainly present in tissues such as the prostate, reproductive skin, epididymis, seminal vesicles, etc. The conversion of testosterone to Dihydrotestosterone (DHT) depending on reduced coenzyme ii, high levels of dihydrotestosterone are prone to androgen-dependent diseases, and down-regulation of androgen levels by inhibiting 5α -reductase activity is an important method for treating androgenic alopecia. 5 alpha-reductase inhibitors have the advantage of selectively blocking dihydrotestosterone synthesis without affecting normal testosterone levels and physiological function. The 5 alpha-reductase inhibitors currently studied can be classified into natural plant-derived components, chemically synthesized steroids, pyridines, quinolinones, phenoxybutanoic acid compounds. Can screen high-efficiency inhibitor by taking 5 alpha-reductase activity as a target spot.
Preparation of 5α -reductase: SPF-class mice/rats are killed after being fasted without water forbidding overnight, livers and epididymis (fat tissues are stripped) are rapidly taken, weighed, rinsed with normal saline, sheared, added with 5 times of precooled homogenate [0.32mol/l sucrose, 1mmol/l DTT,1mmol/l EDTA,20mmol/l PBS (liver pH=7.5; epididymis pH=5.5) ] and homogenized in a glass homogenizer, the homogenate is centrifuged for 10min at 4 ℃ and 3000g, supernatant is centrifuged for 60min at 4 ℃ and 10000g, the supernatant is crude enzyme, split charging is carried out, and the obtained product is stored in an ultralow temperature refrigerator at-80 ℃ and taken out before use, so that repeated freeze thawing is avoided.
The protein content is measured by using a Lowry method protein content detection kit or the Coomassie brilliant blue experiment is quantified, the total protein content in crude enzyme is used for representing the concentration of 5 alpha-reductase, and the operation is carried out according to the specification of the kit.
Preparation of coomassie brilliant blue G250 solution: 100mg of Coomassie brilliant blue G250 was precisely weighed and 50ml of 95% ethanol solution was added. The solution was blue, stirred to dissolve, then 100ml of 85% (W/V) phosphoric acid was added to stir, the solution was reddish in blood, finally deionized water was used to fix the volume to 1000ml, the solution turned brown, stirred on a magnetic heating stirrer overnight, and filtered with filter paper for use. BSA protein standards were gradient diluted to 0.0, 2.5, 5.0, 10.0, 20.0, 40.0, 50.0. Mu.g/ml with PBS. Sequentially adding 50 μl of BSA solution with each concentration into the 96-well plate, sequentially adding 150 μl of Coomassie brilliant blue G250 solution into each well, placing into a multifunctional enzyme-labeling instrument, shaking for 5min, and measuring absorbance at 595 nm. The Bradford protein standard curve is plotted on the abscissa with BSA concentration and on the ordinate with absorbance.
The crude enzyme extract was diluted to an appropriate multiple and the protein mass concentration of the crude enzyme extract was measured by the Bradford method and considered as the 5 a-reductase content.
Inhibition activity of active substance on type II 5α -reductase: adding samples according to the following reaction system, incubating for a certain time at 37 ℃, adding 2ml of precooled methanol to terminate the reaction, uniformly mixing, centrifuging for 5min at 10000r/min, taking supernatant, filtering with a 0.22 mu m filter membrane, and measuring the absorbance value of each sample hole by using a multifunctional enzyme-labeled instrument; or detecting the residual testosterone concentration in the individual samples.
