Dihydromyricetin Natural Sources
Dihydromyricetin (DHM), also known as ampelopsin, is a natural flavonoid compound abundant in Asian plants such as Ampelopsis grossedentata (vine tea). Vine tea is a traditional functional herbal tea from the mountainous regions of southern China. It is one of the plants with the highest flavonoid content in the world and was officially recognized by the Chinese government as a novel functional food ingredient in 2013.
Ampelopsis grossedentata, also known as vine tea or longevity vine, is a deciduous vine in the genus Ampelopsis of the family Vitaceae. It is primarily distributed in China and is also found in Japan, South Korea, the United States, Germany, Mexico, and other countries, with China being its primary distribution area. With a history of more than 1,200 years of use in China, vine tea is a traditional medicinal plant that has been widely used to treat skin diseases, furuncles, osteomyelitis, acute lymphadenitis, and other infectious diseases.
Dihydromyricetin (DHM) powder, one of the major flavonoids in vine tea, exhibits various biological activities, including anti-inflammatory, antioxidant, hepatoprotective, cardioprotective, and skin-protective effects, as well as blood sugar-lowering properties. It has garnered particular attention for its potential roles in alcohol metabolism and liver protection.
Chemical Components In Vine Tea
Vine tea contains rich chemical components, such as flavonoids, polyphenols, steroids, terpenes, polysaccharides, amino acids, essential oils, and trace elements, among which flavonoids are the most abundant, accounting for as much as 43%.
1. Flavonoids
About 30 flavonoids were isolated from rattan tea, including dihydromyricetin, quercetin, myricetin, hesperidin, apigenin and ampelopsis, among which the content of dihydromyricetin was as high as 30%.
2. Polyphenols
The isolated phenolic compounds include gallic acid, galloside, ethyl gallate, gallic acid-β-D-glucose, catechin, epicatechin, and epigallocatechin, etc.
3. Terpenoids and Steroids
Steroids and terpenoids, including stigmasterol, β-sitosterol, oleanolic acid, and ambroxol, were isolated from vine tea.
4. Other Compounds
Vine tea also contains a certain amount of fatty acids, with linoleic acid being the main unsaturated fatty acid (PUFA) and octadecanoic acid being the main saturated fatty acid (SFA). In addition, vine tea also contains water-soluble polysaccharides and volatile substances.

Vine Tea Extract Dihydromyricetin Powder Benefits
Dihydromyricetin For Hangovers
Dihydromyricetin is effective against acute alcoholism, relieves hangovers, and reduces alcohol intake. DHM acts on the benzodiazepine site of the GABA_A receptor, antagonizing the enhancement of GABA_A receptors and neuroplastic changes caused by alcohol, thereby reducing alcoholism, tolerance, anxiety and susceptibility to convulsions; it can also block the increase in α4 subunit expression induced by alcohol exposure/withdrawal.
As a natural flavonoid, DHM is highly safe and does not cause sedation or addiction. It is a high-quality raw material for the development of anti-hangover, liver protection and auxiliary intervention products for alcohol use disorders.
Dihydromyricetin Liver
Dihydromyricetin (DHM) offers significant protective effects against various liver diseases: it alleviates acute liver injury, ameliorates alcoholic and non-alcoholic fatty liver, promotes liver regeneration, and inhibits the proliferation and metastasis of liver cancer cells.
Mechanistically, DHM exerts anti-inflammatory and antioxidant effects, regulates lipid and glucose metabolism, and induces apoptosis and autophagy by activating multiple signaling pathways, such as JNK, p53, AMPK/Sirt1/Sirt3, and Nrf2/HO-1. Clinical studies indicate that it improves blood lipid profiles and liver function in patients with non-alcoholic fatty liver disease (NAFLD). As a liver-protective dietary supplement and functional food ingredient, DHM is supported by solid scientific evidence and holds significant development potential.
Dihydromyricetin Anxiety
Dihydromyricetin (DHM) effectively alleviates anxiety induced by social isolation. It mitigates stress-related brain damage by protecting mitochondria, reducing oxidative stress, and restoring autophagic function, while simultaneously boosting brain-derived neurotrophic factor (BDNF) levels to promote neuronal health.
Additionally, DHM modulates GABA receptors, aiding in emotional stability. As a natural anxiolytic ingredient, DHM is well-suited for use in dietary supplements and functional foods aimed at emotional well-being, helping to relieve the stress and anxiety associated with modern life.
Vine Tea Extract Dihydromyricetin Powder Uses
1.Dihydromyricetin Supplement
Used in the development of hangover relief and liver protection health products to help alleviate alcohol discomfort and protect liver health. Additionally, due to its antioxidant properties, it is also added to dietary supplements that enhance immunity and have anti-aging effects.
2. Functional Foods and Beverages
As a natural antioxidant, it is used in foods such as oils and meat products to delay oxidative spoilage and extend shelf life. It is also added to functional beverages to give these products health claims such as hangover relief and liver protection.
3. Natural Skincare and Cosmetics
It eliminates free radicals, inhibits skin aging-related factors, and reduces wrinkles and fine lines; it is often used in anti-aging dihydromyricetin cream, serums, and other products. It also nourishes hair and scalp and improves the scalp environment.
4.Pharmaceutical field
·Adjunctive treatment for liver diseases: It has a protective effect against alcoholic liver damage and chemical liver damage, and can be used as an adjunct component of hepatoprotective drugs.
·Anti-inflammatory and neuroprotective: Studies have shown that it has potential neuroprotective effects on neurological diseases such as Alzheimer's disease and Parkinson's disease, and works by clearing β-amyloid protein and inhibiting inflammatory responses.
·Anti-tumor research: It has shown inhibitory effects on certain tumor cells in in vitro and animal experiments, and related drug development is in the clinical trial stage.
