Procyanidins, Chinese scientific name oligomeric proanthocyanidins (OPC), is a bioflavonoid with special molecular structure, which is internationally recognized as the most effective natural antioxidant for scavenging free radicals in human body. It is generally reddish-brown powder, slightly smelly and astringent, and easily soluble in water and most organic solvents. Proanthocyanidin is a new type of high-efficiency antioxidant and the strongest free radical scavenger found so far, which has very strong in vivo activity. Experiments show that the anti-free radical oxidation ability of OPC is 50 times that of vitamin E and 20 times that of vitamin C, and it is absorbed quickly and thoroughly. The highest plasma concentration can be reached in 20 minutes after oral administration, and the metabolic half-life can reach 7 hours. Long-term administration of proanthocyanidins can enhance immunity, prevent colds and cancers, resist aging, resist radiation, detoxify and nourish skin.
According to the content of each grape seed and the purity of proanthocyanidins (OPC) contained in it; In addition, it depends on its production process. At present, ethanol extraction technology is widely used in China, while superfluid extraction technology abroad is more advanced. The price of grape seeds ranges from tens to hundreds. Better are some foreign grape brands, such as GNC and Cornelius.
But here I want to tell you:
With the development of the times and the progress of science and technology, the raw materials and technology for extracting proanthocyanidins (OPC) have been well developed. Based on more than ten years' scientific research achievements of professors from Huazhong Agricultural University in China and top experts in OPC in China, the purity of lotus proanthocyanidins extracted from lotus plants by a unique green extraction process (water extraction) is 98%, the content of oligomeric proanthocyanidins is 80%, and its biological activity is 10 times that of grape seeds. It is the OPC with the highest purity, the best absorption rate and the strongest activity in the world so far. Since then, China's OPC extraction technology has reached the world leading level, which is the pride of all China people.
The extraction process of proanthocyanidins has gone through three legendary steps. The development of the third generation OPC:
1. OPC is extracted from pine bark, which represents pycnogenol.
Procyanidins (OPC) were originally extracted from pine bark, so the procyanidins extracted from pine bark are called the first generation procyanidins products.
2. OPC extracted from grape seeds and blueberries are representative products: Lover Grape Seed Capsule, gnc Grape Seed Capsule, Conex Grape Seed Capsule, Taiaofei Grape Seed Capsule, Hilongda Grape Seed Capsule, Amway Grape Seed Capsule and Tian Xuan Grape Seed Capsule.
It is found that the purity and oligomer content of proanthocyanidins extracted from grape seeds and blueberries are high, so the proanthocyanidins extracted from grape seeds and blueberries are called the second generation proanthocyanidins products.
3. OPC extracted from lotus plants, the representative product: Lotus essence brand proanthocyanidins capsules.
Research institutions such as the Human Nutrition Research Center of the United States Department of Agriculture found that lotus plants have the highest proanthocyanidins content and the strongest antioxidant capacity, and are the richest proanthocyanidins resources. Its purity and free radical scavenging ability are much higher than those of proanthocyanidins (OPC) extracted from grape seeds and blueberries, and it is the highest purity, highest absorption rate and strongest activity in the world so far.
Therefore, proanthocyanidins (OPC) extracted from lotus plants are called the third generation OPC products.
The extraction purity of proanthocyanidins from lotus is 98%, and that from grape seeds is only 90%. The content of oligomeric proanthocyanidins is 20% of grape seed proanthocyanidins and 80% of lotus proanthocyanidins. The biological activity of lotus proanthocyanidins is 10 times that of grape seed proanthocyanidins.
Grape seed proanthocyanidins are generally extracted with ethanol, which has a certain influence on the biological activity of proanthocyanidins and contains a small amount of impurities such as ethanol, so it has a certain negative impact on human body.
Lotus proanthocyanidins created a unique green extraction process-water extraction (national patent, patent number: ZL02 1 154236), which mainly extracted oligomeric proanthocyanidins. Compared with similar products at home and abroad, it has more excellent biochemical and pharmacological activities. "Lianjinghua Brand" proanthocyanidins capsules are derived from wild lotus plants in Honghu Lake and are pure natural plant extracts.
Lotus proanthocyanidins, an antioxidant Wang Zhongwang extracted from lotus plants by Lianjinghua Capsule, have much higher purity and free radical scavenging ability than proanthocyanidins extracted from grape seeds and blueberries. So far, it is the substance with the highest purity, the highest absorption rate and the strongest activity in the world. Shi Guojian's word G20050295 was approved by the State Food and Drug Administration of the United States, which is a key national and scientific research project, Lotus Essence Capsule:
★ First Prize of Science and Technology Progress of the Ministry of Education and Hubei Science and Technology Progress Award
★ It has been included in the national "Eleventh Five-Year" high-tech support plan.
★ National Natural Science Foundation of China
★ National Industrialization Fund for Science, Technology and Agriculture Specialty
★ The only designated health care product in the 6th Asian Winter Games.
