Embodiment 1
[0059] Example 1: Optimization of the Extraction Process for the Active Components of D.
[0060] 1. The effect of solid-liquid ratio on the inhibition rate of hyaluronidase activity
[0061] Take by weighing 5 parts of 20.0g dry hair fern powder, respectively according to the solid-liquid ratio of 1:5g / mL, 1:10g / mL, 1:15g / mL, 1:20g / mL, 1:25g / mL Proportional addition of ethanol solution with a volume fraction of 70% (v / v), ultrasonic extraction at a temperature of 30°C for 30 minutes respectively, and the extraction solution was concentrated into an extract after suction filtration. The extract was dissolved into 1% alcohol solution respectively, and then the hyaluronidase inhibition test was carried out to investigate the effect of the ratio of solid to liquid on the inhibition rate of hyaluronidase activity. The results are shown in figure 1 . Depend on figure 1 It can be seen that with the increase of the ratio of solid to liquid, the inhibition of the activity of Tricho...
Embodiment 2
[0079] Example 2: Research on anti-allergy efficacy of 4 kinds of Chinese herbal medicine extracts
[0080] Take 0.1mL 0.25mmol / L CaCl 2 solution and 0.5mL hyaluronidase solution, kept at 37°C for 20 minutes in a water bath; adding sample solutions (respectively, extracts of Trichomonas edulis, extracts of Scutellaria baicalensis, cactus extracts and licorice extracts, all in alcohol solutions with a concentration of 1.0%, The volume fraction of ethanol is 5%) 0.5mL, 37°C water bath for 20min; add sodium hyaluronate solution 0.5mL, 37°C water bath for 30min, and place at room temperature for 5min; add 0.4mol / L NaOH solution 0.1mL, add acetylacetone solution 0.5mL, heated in boiling water bath for 15min, then immediately cooled with ice water for 5min; add 1.0mL Ehrlich reagent, 3.0mL absolute ethanol, develop color for 20min, use deionized water as a control, measure its absorbance at 539nm value.
[0081] Hyaluronidase inhibition rate (%)=[(A-B)-(C-D)] / (A-B)×100%

Embodiment 3
[0087] Embodiment 3: the research of 4 kinds of Chinese herbal medicine extracts inhibiting skin bacteria
[0088] 1) Activation of strains: pick the bacteria with an inoculation ring and streak on the plate, put them into an incubator for upside-down culture (culture at 37°C for 24 hours for bacteria; 48 hours for fungi at 28°C). After the colonies grow, pick a single colony Re-activation by streaking on the plate again. In principle, activation by streaking on the plate three times can achieve the activation of the strain. Take the activated strain, and under sterile conditions, pick a colony with an inoculation loop and add it to the liquid medium , placed in a shaker, bacteria were cultured for 12h-14h at a temperature of 37°C, fungi were cultured for 3d-5d at a temperature of 28°C.
[0089] 2) Preparation of bacterial suspension: Dilute the cultivated bacterial liquid with liquid medium by 10-fold dilution method to make a series of bacterial suspensions, use a hemocytome...
