Embodiment 1
[0050] The preparation method of embodiment 1 Shuixiang rib extract of the present invention
[0051] In one embodiment of the present invention, the whole plant of Shuixianglong is cleaned, and the extraction solvent of the washed whole plant of Shuixianglong and water, alcohol, or a mixture of alcohol and water is taken. The extraction solvent is preferably water, and the extraction solvent is 5- 20: Mixing at a liquid-solid ratio of 1-5, homogenizing and then extracting at 50-100°C for 0.5-3 hours to obtain a crude extract. After cooling to room temperature after extraction, the crude extract was filtered through a 400-mesh filter to obtain a filtrate. Finally, the filtrate was concentrated under reduced pressure at 45-70° C. to obtain the Shuixiang prism extract of the present invention.
Embodiment 2
[0052] Example 2 Anti-inflammatory effects of the ethyl acetate layer extract, n-butanol layer extract, and water layer extract of the Shuixiang rib extract of the present invention
[0053] An embodiment of the present invention is to further test the anti-inflammatory effect of the ethyl acetate layer extract, n-butanol layer extract, and water layer extract of the Shuixiang rib extract of the present invention; wherein, the Shuixiang rib extract The compound was obtained by extracting with water according to the procedure described in Example 1. First, take 5L of Shuixiang rib extract of the present invention and extract 3 times with ethyl acetate and water in a liquid-phase distribution extraction method with a ratio of 1:1. The combined extracts are concentrated and dried under reduced pressure to obtain the ethyl acetate layer extract. A total of 4.3g, while the aqueous layer extract was then continued to be extracted 3 times with n-butanol and water in a liquid-phase di...
Embodiment 3
[0057] Example 3 The effect of the ethyl acetate layer extract, n-butanol layer extract, and water layer extract of the Shuixiang rib extract of the present invention on promoting the proliferation of skin keratinocytes
[0058] One embodiment of the present invention uses HPEK-50 cells to respectively test the effects of the ethyl acetate layer extract, n-butanol layer extract, and water layer extract on promoting the proliferation of skin keratinocytes. First, in a 96-well culture dish, 3×10 3Individual human primary skin keratinocytes were cultured at 37°C for 2 hours with the above-mentioned culture solution, and the cells were divided into the following five groups: (1) a blank control group that only added cell culture solution, (2) adding 100 μg / mL of the water of the present invention The stock solution group of the cypress extract, (3) the experimental group adding 100 μg / mL aqueous layer extract, (4) the experimental group adding 100 μg / mL ethyl acetate layer extract...
