Production Description

Polygonum cuspidatum extract is the rhizome of Polygonum genus. This product is mainly composed of resveratrol and emodin. Its chemical structure is C14H12O3. Resveratrol and emodin are the main functional ingredients in Polygonum cuspidatum.

Resveratrol was discovered as early as 1924 and was first isolated from the roots of Veratrum grandiflorum by the Japanese in 1940. In 1976, Res (resveratrol) was discovered in the leaves of grapes. It is an antitoxin secreted by plants when they encounter adversity or pathogen attack. Its synthesis increases sharply when exposed to ultraviolet rays, mechanical damage, and fungal infection. Therefore, Called phytoantibiotics (phytoalexin). Res has been found in more than 700 species of plants, including 72 species of plants in 31 genera and 12 families, with higher levels in human foods such as grapes, knotweed and peanuts.

Natural resveratrol has two structures, cis and trans. It mainly exists in trans conformation in nature. The two structures can be combined with glucose respectively to form cis and trans resveratrol glycosides. The cis- and trans-resveratrol glycosides can release resveratrol under the action of glycosidases in the intestine. Under UV light irradiation, trans-resveratrol can be converted 

into the cis-isomer. Resveratrol and its glycosides.

Resveratrol produced by Hunan Huakang Biotech Inc. It’s extracted from the dry roots of Polygonum cuspidatum Sieb. and grape skin, its rich with Both cis - resveratrol and trans-resveratrol. Resveratrol in plants mainly exists in the form of  trans-resveratrol, and studies show that the physiological activity of Trans is stronger than Cis. Resveratrol is tasteless white crystal (methanol); Soluble in water, ethanol, acetone, etc.Melting point of 253-255 centigrade , sublimation point of  261 centigrade.

Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.

Resveratrol is a polyphenic bioflavonoid antioxidant that’s produced by certain plants and found in foods and drinks that are known to halt the effects of aging. Resveratrol is classified as a phytoestrogen because of its ability to interact with estrogen receptors in a positive way. Plants that produce resveratrol and other types of antioxidants actually do so partly as a protective mechanism and response to stressors within their environments, including radiation, the presence of insects or other predators, injury, and fungal infections. Today, resveratrol is believed to be one of the most potent polyphenols and strongest protectors against symptoms associated with aging and free radical damage.
