![]() During World War II, the US Army developed a special airdrop supply carrier that could carry up to 65 pounds (29 kg) of supplies and was based on the maple seed. People often call them "helicopters" due to the way that they spin as they fall. They are shaped to spin as they fall and to carry the seeds a considerable distance on the wind. These seeds occur in distinctive pairs each containing one seed enclosed in a "nutlet" attached to a flattened wing of fibrous, papery tissue. The distinctive fruits are called samaras, "maple keys", "helicopters", "whirlybirds" or "polynoses". It is one of the most common genera of trees in Asia.ģD rendering of a ♜T scan of a samara. Maple syrup is made from the sap of some maple species. The closest relatives of the maples are the horse chestnuts. Maples usually have easily recognizable palmate leaves ( Acer negundo is an exception) and distinctive winged fruits. ![]() The type species of the genus is the sycamore maple, Acer pseudoplatanus, the most common maple species in Europe. Only one species, Acer laurinum, extends to the Southern Hemisphere. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. ![]() The genus is placed in the family Sapindaceae. “Many botanical ingredients traditionally come from China, India and the Mediterranean,” Seeram explains, “but the sugar maple and the red maple only grow in eastern North America.”Īnd because the leaves of maple trees could be harvested during their natural autumn pruning, Maplifa is not only economically beneficial, but environmentally friendly and sustainable, too.Acer pseudoplatanus (sycamore maple) foliageĪcer ( / ˈ eɪ s ər/) is a genus of trees and shrubs commonly known as maples. Moreover, if maple leaf extracts are as successful as Seeram anticipates, Maplifa could greatly improve the livelihoods and increase the incomes of US and North American farmers. GCGs may also act as protective agents against inflammation, age spots and freckles, and could even lighten unwanted dark spots. In previous studies conducted by Seeram and team, these incredible compounds called glucitol-core-containing gallotannins (GCGs) show even more promise than the inhibition of elastase. ![]() “We wanted to see whether leaf extracts from red maple trees could block the activity of elastase,” describes Hang Ma, PhD, from the University of Rhode Island.Īccording to Ma and his group’s findings, presented at the 256th National Meeting & Exposition of the American Chemical Society, certain phenolic compounds extracted from maple leaves have the potential to decelerate and even prevent the elastase enzyme’s breakdown of elastin. But as we grow older, our bodies begin looking for new and underused sources of protein, causing the pancreas to release an enzyme known as elastase-the purpose of which is essentially to digest elastin. #Maple leaves skin#Proteins such as collagen and elastin help reinforce connective tissues, giving youthful skin its smooth, supple appearance and ability to maintain this shape. “You could imagine that this extract (Maplifa) might tighten up human skin when applied as a topical application,” says a confident Seeram. It was after this study that Seeram began to speculate about other parts of the maple tree and potential health benefits that they may hold. In 2017, they uncovered how the prebiotic properties of maple sap could combat chronic inflammation, liver disease, and metabolic syndrome by supporting the growth of healthy bacteria and restoring gut flora balance. Seeram, PhD, and researchers from the Department of Biomedical and Pharmaceutical Sciences at the University of Rhode Island have been studying the chemical composition of sugar maple and red maple trees for their therapeutical benefits. ![]() Newly licensed by Verdure Sciences, Maplifa is an extract from red maple leaf, and according to researchers at The University of Rhode Island, might help slow down the process of skin aging. ![]()
