KINTAI Selection of raw materials for vine tea:

Our researchers compared the effects of different origins, parts and processing techniques on the dihydromyricetin content in vine tea.  Ampelopsis grossedentata (Hand.-Mazz.) W. T. Wang is a wild woody deciduous vine of the genus Ampelopsis in the family Vitaceae, commonly known as vine tea, white tea, etc. Its production areas are mainly distributed in Hunan, Hubei, Yunnan, Guizhou, Guangdong, Guangxi, Fujian, and other places in China.

Research shows that the content of dihydromyricetin in vine tea from different origins varies significantly. Among them, the vine tea produced in Jiangkou County, Guizhou Province is particularly outstanding in terms of active ingredient content and stability.

Origin of raw materials

Jiangkou County, Guizhou Province: Vine tea has become an ideal raw material for high-quality dihydromyricetin due to its unique geographical and climatic conditions. Jiangkou County is located at the foot of Fanjing Mountain. It has a superior ecological environment and fertile soil, which is suitable for the growth of vine tea. After the vine tea produced here is naturally dried, the dihydromyricetin content in the bud tips is the highest, showing significant quality advantages, making it the first choice for our company to purchase vine tea raw materials.

Raw material parts

Harvesting methods and parts: Harvesting methods are divided into manual harvesting and machine harvesting. The harvesting parts include bud tips, young leaves, thick old leaves and tea stems. Research has found that there are significant differences in the content of dihydromyricetin in different parts of vine tea. The best vine tea is the shoot tips and young leaves, as these parts have the highest dihydromyricetin content. In contrast, the content of thick old leaves and tea stems is low and affects the overall quality and efficacy of vine tea. Therefore, in the production process, selecting shoot tips and young leaves as raw materials is an important measure for us to ensure product quality.

Selection of processing technology：Natural sun drying

The processing technology of vine tea also has a significant impact on the content of dihydromyricetin. The natural sun-drying process can retain the dihydromyricetin in vine tea to the greatest extent. Therefore, when purchasing raw materials for vine tea, we prefers natural sun-drying methods for processing vine tea, which can significantly improve the extraction efficiency of dihydromyricetin.

(1) Antibacterial effect

Pharmacological experiments have shown that Vine tea extract DHM has an inhibitory effect on Staphylococcus aureus,Bacillus subtilis, Escherichia coli, Salmonella, Bacillus aeruginosa, Brewer's yeast, Saccharomyces cerevisiae, Penicillium, Aspergillus niger, Aspergillus flavus, Trichoderma reesei and Rhizoctoniae, especially on Gram-positive and Gram-negative cocci or bacilli.

(2) Regulatory effects on blood glucose and blood lipids 

The experiment shows that dihydromyricetin significantly reduces the elevation of blood glucose levels induced by alloxan, epinephrine and streptozotocin, and also increases the serum insulin level, significantly reduces the infiltration of lymphocytes into the pancreatic tissue and significantly reduces inflammation. The number has increased significantly. 

(3) Liver protection 

Vine tea extract Dihydromycetin protects the liver, promotes rapid degradation of acetaldehyde, an ethanol metabolite, and converts it into non-toxic substances to reduce damage to hepatocytes. In addition, dihydromycetin improves the increase in serum lactate dehydrogenase activity caused by damage to hepatocytes, inhibits the formation of collagen fibers in liver M cells, This protects the liver and greatly reduces damage to the liver by ethanol.The microherbal test demonstrates that dihydromycetin protects the liver, facilitates the rapid degradation of acetaldehyde, a metabolite of ethanol, and converts it into non-toxic substances and reduces damage to hepatocytes. Dihydromycetin is an excellent product with immediate efficacy and persistence, protecting the liver and softening hangover.

(4) Antioxidant effect
 

The effect of inhibiting MDA production increases with increasing levels of dihydromycetin. Dihydromethylcetin for diphenyl trinitro phenylhydrazine (DPPH) free radical in a 99% capture rate assay system. Dihydromycetin can significantly inhibit the formation of MDA in oil, and the higher the purity (60% to 90%) of dihydromycetin, the higher the antioxidant effect, and the potent antioxidant effect on animal oil and vegetable oil.

Food and beverage industry:

DHM can be used as a food additive to keep food fresh and extend shelf life. It can be used as an antioxidant, preservative and nutritional enhancer in fruit and vegetable products, candies, beverages, etc.

1.Blocking the effect of alcohol on GABA receptors in the brain:

DHM can bind to GABA receptors in the brain and block the effect of alcohol on GABA receptors. This reduces the stimulant effects of alcohol on the central nervous system, thereby relieving hangover symptoms such as headaches, nausea, and fatigue.

2.Enhancing Alcohol Metabolizing Enzyme Activity:

DHM can enhance the activity of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) in the liver. These two enzymes are the key enzymes involved in the metabolism of alcohol. ADH metabolizes alcohol into acetaldehyde, while ALDH further metabolizes acetaldehyde into harmless acetic acid. By enhancing the activity of these enzymes, DHM can accelerate the metabolism of alcohol and reduce the accumulation of acetaldehyde, thereby reducing alcohol damage to the liver.

3.Antioxidant properties: DHM has significant antioxidant properties that can neutralize free radicals in the body and reduce damage to body tissues caused by oxidative stress. Alcohol metabolism triggers a large number of free radicals, which can cause oxidative damage to the liver and other organs, and the antioxidant effect of DHM can protect these organs from damage.
