Keywords:Cerasus speciosa, coumarine, Geological components
In Matsuzaki Town, Shizuoka Prefecture, in the West Izu region, the production of pickled cherry leaves from Oshima cherry trees is flourishing. Coumarin is an insecticide and an aromatic component of cherry leaves. It is widely believed that the cherry leaves produced in Matsuzaki Town have a high coumarin content and a good aroma, making them highly valuable as a product.
We collected cherry leaves of Someiyoshino cherry trees and Oshima cherry trees from 20 locations around the Izu Peninsula in July 2023. We salted them for about three months and asked experts to measure their coumarin content.
The results showed that the coumarin content of the Oshima cherry in Matsuzaki Town was not high. It was different from the myth. The coumarin content of the coastal cherry trees varied. Native cherry trees tended to have higher levels of coumarin.
Results indicate that the harsh environment affected the differences in coumarin content, a protective substance.
