| birch bark extract | betulin (Betulin), also known as betulin, betulin, betulin, is a kind of triterpene extracted from birch bark. The use of compounds in bark is unknown, but they can be used as betulinic acid (carboxylic acid group substituted alcohol group) and other compounds with more biological functions The precursor. |
| extraction method | currently, the way to obtain betulin is mainly through direct extraction, mainly through solvent reflux extraction method and recrystallization purification method, specifically: 1. betulin is extracted with ethanol solution, heated and refluxed for about 5 hours, the extract is decompressed and distilled, then recrystallized with ethanol for 2-3 times to obtain a crude betulin product. 2. the crude product is recrystallized with methanol/chloroform (1:1), and 80g of crude product requires about 300mL of methanol and chloroform solution; Let stand overnight and filter to obtain white needle-like betulin solid. 3. ultrasonic treatment of the extract was designed for 20min during reflux, and the extraction rate and product purity of betulin were improved by destroying the bark tissue. 4. the optimal extraction conditions of supercritical CO2 fluid are as follows: the dosage of modifier is 115 mL/g birch bark powder; The extraction pressure is 20MPa; The extraction temperature is 55 ℃; The flow rate of liquid CO2 is 10kg/h. |

| physiological effects of betulin | 1. betulin and its derivatives as biological agents show great potential in the treatment of HIV and cancer. it works by interfering with the latter stage of the virus life cycle and is related to the entry and growth of the virus. 2. Effective anti-tumor drugs directly cause certain types of tumor cells to initiate self-destructing apoptosis procedures, and can slow down the growth of several types of tumor cells. 3. It can reduce diet-induced obesity, reduce lipid content in serum and tissues, and improve insulin sensitivity. 4. They have mild anti-inflammatory properties at higher concentrations, and their anti-inflammatory properties are mainly due to inhibition of non-neural gene pathways. 5. Betulin can inhibit the maturation of sterol regulatory element binding proteins (SBERPs) in vivo, thus reducing the biosynthesis of cholesterol and fatty acids. 6. In addition, it also has the activities of inhibiting protein dissolution in hair fibers, improving damaged hair luster, promoting hair growth, etc. It can be used in food, cosmetics, medicine and other industries. |
| store | cool and dry, away from light and high temperature. |
| use | used for content determination/identification/pharmacological experiments, etc. Pharmacological effects: anti-inflammatory, anti-viral, inhibit protein dissolution in hair fibers, improve damaged hair luster, promote hair growth and other activities. it has anti-inflammatory, anti-virus, inhibiting protein dissolution in hair fibers, improving damaged hair luster, promoting hair growth and other activities, and can be used in food, cosmetics, medicine and other industries. |
