Embodiment 1
[0050] [Example 1] Production of edeltoxin
[0051] The extract of Edelweiss alpina (2 kg) dried in a cool place at room temperature was collected by repeated cold soaking with methanol three times every week, and concentrated under reduced pressure to obtain 160.5 g of methanol extract. The methanol extract was suspended in distilled water and partitioned with hexane (25.2g), then the remaining aqueous layer was re-divided with ethyl acetate to obtain an acetonitrile fraction (20.4g), and then the remaining aqueous layer was re-divided with butanol And get the butanol extract (20.6g) and finally get 40.6g of water.
[0052] Then, use methanol to dissolve 40.6 g of the above-mentioned water containing surface materials and use a glass column filled with silica gel ( 7734, Merck Corporation) and a mixed solvent of water, acetonitrile, and methanol to dissolve the active material to obtain 10 subdivisions. Among them, the sub-hollow column chromatography analysis was carried out on...
Embodiment 2
[0053] [Example 2] Production of leontoxic acid stabilized into nanoliposomes
[0054] In order to stabilize the above-mentioned leontoic acid into nanoliposomes, 580 g of glycerol, 200 g of caprylic capric triglyceride, 50 g of phospholipids, and 20 g of cholesterol were mixed with a blender and heated to 75°C. After mixing and dissolving, add from the above example 1 Obtain 50g of edelontoic acid solid powder and dissolve it completely. Here, 100 g of purified water was slowly added, mixed, and passed through a three-time high-pressure softening device (Microfluidizer M210EH, Microfluidics, USA) 3 under the adjustment of a pressure of 1000 mbar at 50° C. to prepare nanoliposomes of leonoronic acid. The particle size of the liposome is about 70 nm.

[0055] [Experimental example 1] Testing the promoting effect of collagen biosynthesis
[0056] Compare with a tocopherol and EGCG that can promote collagen biosynthesis to test the collagen biosynthesis promoting effect of Example 1 above.
[0057] First, seed 10 in each of the 24 wells (well) 5 Personal fibroblasts (PromoCell, Germany) were cultured to 90%. Then it was cultured in serum-free DMEM medium for 24 hours, and the tocopherol and EGCG of Example 1, which were melted in serum-free medium, were treated at 10-4 molar concentrations and treated in CO 2 Cultivate for 24 hours in the incubator. Salvage the upper layer of these liquids and use the procollagen type (I) enzyme-linked immunosorbent assay (ELISA) tool (procollagen type (I)) to check whether the procollagen (procollagen) increases or decreases. The results are shown in Table 1 below. Here, the synthesis ability is compared with the non-treatment group being 100.
