About Acer Truncatum

Acer truncatum bunge (Shantung maple, Shandong maple, or purpleblow maple) is a maple native to northern China. Acer truncatum bunge produces Nervonic acid, an extract from its seeds, that is the principal extract from which acer truncatum oil is derived. As a monounsaturated omega-9 fatty acid, nervonic acid is believed to be beneficial to memory-related brain health, anti-aging, blood lipid regulation, anti-fatigue. Omega 9 includes several types of fats. However, four of them which are the most important: oleic acid, mead acid, erucic acid and nervonic acid. Nervonic acid has been identified as important in the biosynthesis of nerve cell myelin. It is found in the sphingolipids of white matter in human brain. Nervonic acid is used in the treatment of disorders involving demyelination, such as adrenoleukodystrophy and multiple sclerosis where there is a decreased level of nervonic acid in sphingolipids. 

 

Scientific research reveals that nervonic acid can advance the re-growth of neurons. It can possess several medical effects, such as, repairing and dredging the speedway of transferring nervonic information nerve fiber to dredge the brain route, repair the injured cranial nerve cells, and advance the re-growth of cranial nerve.

Nervonic acid can also increase the energy of brain cells, advance the multiplication and differentiation of cells, prevent the cranial nerve cells from consenescence and injury, recover the clear perceive ability, distinguishing ability, study ability and memory. Nervonic acid may be effective to prevent senile dementia.

 

Nervonic acid is known as selacholeic acid and is usually found in the sphingolipids of white matter in the human brain, with the highest content in the neural tissues and brain tissues, being an important part of the cell membranes. In Europe and the United States, it is mainly extracted from shark brains or shark oils. The extraction process and technique are difficult, and the final cost can exceed US$ 45,359 per pound. In addition, certain species of sharks are protected by the United Nations and many countries in the world, so animal sources of nervonic acid are not as acceptable as in the past. Biosynthesis from chemicals or other intermediates are not presently available because either the yield is low or too many unhealthy by-products are produced.

 

Therefore, the most efficient principal sources of nervonic acid are plants and herbs. According to “Physicochemical Properties of Acer Truncatum Seed Oil Extracted Using Supercritical Carbon Dioxide”, a paper published on the Journal of the American Oil Chemist’s Society

 on April 12, 2017, acer truncatum bunge seed oil rich in nervonic acid was extracted using supercritical carbon dioxide. GC (Gas Chromatography) analysis revealed that the oil contained approximately 6.22% nervonic acid. Acer truncatum bunge seed oil has a high potential in functional foods for i

mproving human health. Therefore, the seed oil may be considered as a potential new source for natural nervonic acid.

 

Malania oleifera is also rich in nervonic acid.  It is native to southern China in the western provinces such as Guangxi and southeastern Yunnan. Its content of nervonic acid is up to 40.92% to 50% of the lipid (usually triglyceride). However, Malania oleifera is a threatened species, and it is on the list of key wild plants for state protection. Therefore, there is no opportunity for commercial extraction form wild malaria oleifera. Cultured malania oleifera plants are experimental in some areas. Therefore, we believe that acer truncatum bunge is the best natural source for the highest yield of nervonic acid.

 

The table below is a list of natural food resources of nervonic acid from both plants and animals, with nervonic acid content in mg/100g:

We believe that favorable claims regarding nervonic acid from several independent studies are credible. While we rely on these independent studies for guidance, we cannot verify these claims with any degree of certainty.

 

We believe that demand for high-quality/low-price acer truncatum bunge seed bunge oil will increase in part due to demand from elderly Chinese and its use as a health supplement. We sell acer truncatum bunge seed oil for approximately 1,000 RMB/kg (approximately $67.41 per pound).The annual production of acer truncatum bunge oil in China was only about 12.4 tons (approximately 27337.32 pounds) in 2017.

 

2017 Annual Production of Acer Truncatum Bunge Seed Oil in China (1 ton equals 2204.62 pounds)

 

Acer truncatum bunge is native to the provinces of Gansu, Hebei, Henan, Jiangsu, Jilin, Liaoning, Inner Mongolia, Shaanxi, Shandong, and Shanxi, and to Korea Traditionally, acer truncatum bunge is an important tree species for afforestation and soil and water conservation, which brings social and ecological benefits. Acer truncatum bunge can be artificially planted to bear fruits (seeds) four to six years after being planted, reaching its full potential in about eight to ten years after being planted. An artificial cultivation of 33 trees per mu (approximately 0.16 acre) is recommended, and about 30 kilogram (kg) (approximately 66.14 pounds) of acer truncatum bunge bunge seeds per tree can be yielded during the flourishing period. Therefore, if the maximum number of trees per mu are flourishing, they can yield up to 1,000 kg (approximately 2,204.62 pounds) per mu. An average of 500 kg (approximately 1102.31 pounds) of acer truncatum seeds per mu can be the yield if the trees are of different ages.
