Earlier studies on the Japanese chestnut have proven to be promising. In a study published in the Journal of Agricultural and Food Chemistry, researchers from Chonnam National University in South Korea found that the tree contained quinolinone alkaloids, known for their possible anti-cancer properties. Other studies also revealed that it has potent antioxidant properties, as well as the ability to regulate the production of melanin.
In this study, the South Korea team looked at how extracts derived from Japanese chestnut affected the formation of adipocytes. In particular, adipocyte cells are linked to the development and buildup of fat cells in the body. They also looked at the main compounds in the extract responsible for the biological activity.
The researchers found that after the 3T3-L1 cells were exposed to the chestnut flower extracts, these exhibited a reduction in lipid cell build up, especially those in the 3-isobutyl-1-methylxanthine/dexamethasone/insulin (MDI) medium. Phytochemical analysis of the extract revealed 10 compounds; among them, the researchers identified cinnamyl alcohol to have dose-dependent inhibition on lipid cells in the MDI medium. In particular, cinnamyl alcohol demonstrated significant inhibition properties without harming relatively healthier cells.
In sum, the researchers concluded that both cinnamyl alcohol and Japanese chestnut flower extract can be used for both preventive and curative therapies for obesity.
While the study looked at chestnut flowers, most people know chestnuts for the edible nuts that come after the flowering stage. One of these species is the Japanese chestnut, a tree native to Japan and South Korea. The nuts are known to form during the autumn: During this time, the female flowers develop into cupules, each with around three to seven nuts.
It's also worth noting that Japanese chestnuts, like other members of the Castanea genus, are packed with health benefits.
