Brief Introduction:

Our Dihydromyricetin is isolated from the Vine Tea. The Vine tea is made by the leaves of the plant-- Ampelopsis grossedentata (Hand-Mazz)W.T.wang. The Dihydromyricetin has the function of clearing the free radical in human body, antioxidation,  antithrombotic effect, anti-tumor, diminishing inflammation, protecting the liver.    

What is Dihydromyricetin?  

Dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) is a natural antioxidant with good prospects. The physicochemical properties of dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) were analyzed by ultraviolet–visible spectrometry, infrared spectrometry, scanning electron microscopy, differential scanning calorimetry, Xray diffractometry. The result showed that dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) and Lecithin inthe complex were combined by non-covalent bond, did not form a new compound and the solubility of dihydromyricetin in n-octanol was significantly enhanced.   

  Function:

1.  Clearing the free radical in body and antioxidation.

2.  Antibiotic Action.

3.  Protecting the Liver.

4.  Reducing the levels of blood sugar and blood fat.

5.  Anti inflammation.

6.  Anti-tumor.  

Application:  

1.  Clearing heat and dampness.  

2.  Repressing hyperactive of Liver and reduce blood pressure.  

3.  Promoting blood circulation and freeing channel.  

4.  Protect liver & Drunkenness curing.
