Embodiment 1
[0070] Embodiment 1. The preparation method of Cyclocarya paliurus extract
[0071] In this embodiment, the preparation steps of Cyclocarya paliurus extract are as follows:
[0072] 1. First, carry out the crushing procedure. The leaves of Cyclocarya paliurus (Origin: China) were coarsely crushed (Osterizer brand 10speed blender) and sieved with a sieve with a hole diameter of 12 mm to remove oversized particles to obtain Cyclocarya paliurus coarse crushes.
[0073] 2. Next, in the heating process, water is used as a solvent and the coarse crushed Cyclocarya paliurus is mixed at a weight ratio of 30:1 (liquid-solid ratio), and extracted at 85±5°C for about 60 minutes to form an extract. In this example, the weight ratio of the solvent to the coarse crushed Cyclocarya paliurus is 20:1, the temperature during soaking is 80° C., and the extraction time is 60 minutes. If the solvent is too small or the extraction time is too short, the extraction efficiency will be significantly...
Embodiment 2
[0079] Embodiment 2. Cell basal metabolic rate test
[0080] The basal metabolic rate refers to the energy consumed by the body to maintain basic functions. The higher the basal metabolic rate, the more energy the body consumes, and the easier it is to have a body that is easy to lose weight. That is, increasing the basal metabolic rate can effectively help prevent and improve obesity.
[0081] In order to investigate the effect of Cyclocarya paliurus extract on the basal metabolic rate of cells, this example uses the amount of the final product of metabolism, pyruvate (Pyruvate), to determine the basis of mouse myoblast C2C12 treated with Cyclocarya paliurus extract. Changes in metabolic rate.
[0082] Materials and Instruments
[0083] 1. Cell line: mouse myoblast C2C12, obtained from BCRC; Cat.60083.
[0084] 2. Culture medium: Dulbecco's Modified Eagle's Medium (DMEM, purchased from Gibco, 12100-046) was added with additional components to make it contain 10vol% FBS (fet...
Embodiment 3
[0109] Example 3. Cyclocarya paliurus extract inhibits fat accumulation efficacy test
[0110] Fat is stored in fat cells in the form of oil droplets. Based on this, this test analyzes the stained oil droplets to observe the number of oil droplets in the cells, so as to confirm the state of fat accumulation. Subsequently, the dye is dissolved and analyzed as a quantitative numerical index.
[0111] In this experiment, mouse bone marrow stromal cells (hereinafter referred to as OP9 cells) were used. OP9 cells were purchased from the American Type Culture Collection (American Type Culture Collection, ) OP9 cell line (ATCC CRL-2749).
[0112] First, take a 24-well culture plate and inoculate each well with 8×10 4 OP9 cells and 500 μL medium (Medium), the medium is MEMAM (Minimum Essential Medium Alpha Medium, purchased from Gibco, product number Cat. , purchased from Gibco, product number Cat.10437-028) and 0.1% penicillin / streptomycin (Penicillin-streptomycin, purchased fro...
