[0058] Preparation of asparagus extract
[0059] Crush the rhizomes of Asparagus Radix, reflux and extract with 10 times the weight of water, remove the solvent from the extract under negative pressure conditions (0.04 to 0.08MPa, 75±6°C), extract the solid extract, spray dry, crush and sieve .
[0060] The asparagus extract can also be purchased from the market, or prepared according to the standards and methods in the Chinese Pharmacopoeia.
[0061] Preparation of rehmannia glutinosa extract
[0062] Rehmannia glutinosa is crushed, extracted with 8 times the weight of water, and the extract is concentrated under negative pressure (0.04 to 0.08MPa, 75±6°C) to a specific gravity of 1.07 to 1.09g / cm 3 (75±6°C), after spray drying, crush and sieve. The rehmannia polysaccharide weight content is ≥50%.
[0063] The rehmannia glutinosa extract can also be purchased from the market, or prepared according to the standards and methods in the Chinese Pharmacopoeia.

Embodiment 1
[0067] Example 1, Asparagus, Radix Rehmanniae, Ginseng Extract and the Composition of Three Extracts Tested for the Proliferation Activity of Fibroblasts
[0068] Materials and Reagents
[0069]
[0070] Method and steps
[0071] Monolayer cells in log phase were trypsinized and harvested into cell culture medium.
[0072] Centrifuge at 1000rpm for 2min and discard the supernatant. Cells were resuspended in culture medium and counted. Adjust the concentration of the cell suspension to 2.5×10 3 to 50×10 3 cells / mL, depending on the growth rate of the cell line.
[0073] Spread 135 μL of cell suspension in each well of a 96-well plate. The final number of cell wells to be plated depends on the number of samples, and each sample has 3 replicate wells. Finally, 3 wells were left without cells as blank control.
[0074] Place the 96-well plate at 37 °C with 5% CO 2 Incubate for 24 h in a cell culture incubator.
[0075] After diluting the sample to be tested with t...
Embodiment 2
[0082] Example 2, the influence of asparagus, rehmannia root, ginseng extract and the composition of three kinds of extracts on the SOD level in skin fibroblasts
[0083] Materials and Reagents
[0084]
[0085]
[0086] Method and steps
[0087] Plating cells: trypsinize the monolayer of cells in the logarithmic phase, and collect the cells into the cell culture medium. Cells were resuspended in culture medium and counted. Adjust the concentration of the cell suspension to 5×10 4 cells / mL, depending on the growth rate of the cell line. Pave a 24-well plate with 0.9 mL of cell suspension per well. The final number of cell wells to be plated depends on the number of samples, with 4 replicate wells for each sample.
[0088] Adding the test substance: continue to incubate for 12 hours after adding the test substance.
[0089] Extract cellular RNA, extract the total RNA of the sample with an ultra-pure RNA extraction kit, add 150 μl of lysate to each well to lyse t...
