Dihydromyricetin, referred to as DMY or DHM, is also known as Aampelopsin, AMP, Ampelopsin, dihydromyricelin, Fujian tea pigment, etc. It is a dihydroflavonol flavonoid compound. In 1940, this component was first isolated from the leaves of Vitis elegans and was widely found in the family Apodaceae genus plants. Among them, rattan tea has the most abundant content, as high as 37.4% to 38.5%. On the market, the mainstream specification of this ingredient is 98% Dihydromyricelin Powder Vine Tea Extract. Nutri Avenue focuses on the application markets for this ingredient.
4 Major Application Areas Of Vine Tea Extract Dihydromyricetin Powder
Dihydromyricetin Powder In The Pharmaceutical Market
- Anti-tumor Effect
Studies on anti-tumor effects in vitro and in vivo have found that the compound can improve tumor treatment effects and patients’ vital symptoms in two ways, as below.
- It inhibits the growth of tumor blood vessels.
- It regulates and enhances cellular immune function.
In experimental studies on tumor models such as leukemia and nasopharyngeal carcinoma, it has been shown to have obvious tumor inhibitory effects.
In addition, scientific researchers have discovered its efficacy in treating postoperative intimal hyperplasia. The efficacy of this ingredient has also been confirmed in drugs. The first is to reverse the transformation of smooth muscle cells from differentiation to synthesis. The second is to inhibit the proliferation of vascular smooth muscle cells.
Dihydromyricetin Vine Tea Extract In Cosmetics
- Antibacterial Effect
Multiple studies have shown that dihydromyricetin vine tea extract has antibacterial effects on many of the following substances.
- Bacillus subtilis
- Staphylococcus aureus
- Escherichia coli
- Aerobacter aerogenes
- beer yeast
- red yeast
- Aspergillus niger
- Aspergillus flavus
- Rhizopus, etc.
Among them, this ingredient has a particularly obvious effect on Gram-positive and Gram-negative cocci or bacilli.
- Antioxidant Effect
Dihydromyricetin powder has a white appearance. It is fat soluble. It shows that it has a good effect on scavenging free radicals on the skin’s surface. Therefore, it can be used as an anti-wrinkle raw material in sunscreen skin care products.
Application Of Dihydromyricetin Powder In Food
Due to the excellent antibacterial activity of this ingredient, it can be applied to the antibacterial preservation of food. At the same time, as an excellent natural antioxidant, it can also be added to food to play an antioxidant role.
- Antibacterial Effect
Plant polyphenols mainly have antibacterial effects in the following ways.
- destroying microbial morphology
- disrupting sodium and potassium ion channels
- interfering with energy metabolism
- inhibiting the synthesis of biological macromolecules, such as proteins, DNA, and RNA
As a plant polyphenol, dihydromyricetin also exhibits superior antibacterial activity.
Staphylococcus aureus has become a focus of attention in the food industry due to its strong toxicity and easy adhesion to food surfaces. Studies have shown that dihydromyricetin with a concentration range of 0.25 to 1 mg/mL can significantly inhibit the formation of Staphylococcus aureus biofilm. And affect its metabolic activity. A similar study also showed that the minimum inhibitory concentration of this natural plant polyphenol against Staphylococcus aureus was 0.06 mg/mL. In addition, its minimum inhibitory concentration against Escherichia coli, Shigella Flexneri, and Bacillus subtilis is below 1 mg/mL. Dihydromyricetin can inhibit bacterial reproduction by inhibiting the respiratory metabolism of bacteria.
- Anti-oxidize Effect
At present, antioxidants added to food mainly include butylated hydroxyanisole (BHA), dibutylated hydroxytoluene (BHT), Tert-butylhydroquinone (TBHQ), etc. However, due to safety issues with synthetic antioxidants, consumers prefer natural antioxidants.
Studies have shown that adding vine tea extract containing 22.6% dihydromyricetin to soybean oil and cooked beef. Soybean oil containing dihydromyricetin has the lowest peroxide and anisidine values compared to added synthetic antioxidants. Moreover, dihydromyricetin in cooked beef also shows good antioxidant activity. Although dihydromyricetin vine tea extract can be added to the oil system as an antioxidant, attention should also be paid to the addition time. Otherwise, this will also have the opposite effect.
A team once conducted a study titled “Exploring the Effect of Dihydromyricetin on the Degradation of TMAO and Related Quality in Fried and Grilled Squid Fillets.” The results showed that it can significantly inhibit the degradation of TMAO in squid products to produce FA, DMA, and TMA. It can improve the safety of squid products and improve the color and texture properties of squid products. It can also slow down fat oxidation and reduce bad odors caused by microbial action during storage. It maintains the good flavor of the squid. It also weakens the flow of water in grilled squid fillets. It can enhance water holding capacity and extend shelf life.
Application Of Dihydromyricetin Powder In Feed
Vine tea extract has antibacterial, antioxidant, and growth-promoting effects on livestock, poultry, and fish. It can improve production performance and feed returns, enhance animal immunity, and improve meat quality. It can prevent and treat retarded growth, indigestion, gastrointestinal inflammation, weak egg production, and other diseases in livestock and poultry. It is an ecological, natural, organic, healthy, safe, and harmless plant-derived feed additive. For example, 3-6 grams of vine tea extract can be added to every 1 kilogram of feed for young poultry. Adult poultry or chickens can add 2-3 grams per kilogram of feed.
