Extracts of Quercus dentata leaf

Abstract

Along with the development of our economic society and the growing demand for wood, the value of the use of Quercus dentata Thunb has also increased year by year. However, the traditional trees used are resources that are cut down, and development primarily uses only the branches, while ignoring the value in using the rest of the trees. Thiscauses a waste of resources. In response, this study uses benzene, an alcohol found in Quercus dentata Thunb leaf extract. Fourier transform infrared spectroscopy (FT-IR) and gas chromatography-mass spectrometry (GC-MS) were used for catalytic cracking products, and the efficient extraction of pyrolysis products were studied. Analysis shows that Quercus dentata Thunb leaf extract species contain a variety of biological active ingredients; and the ingredients in pharmaceutical and chemical production have very high value. For example, the Quercus dentata Thunb leaf of benzyl alcohol extract, Lupeol, has significant anti-cancer, anti-oxidation, and anti-inflammatory effects. The analysis of the chemical composition of the Quercus dentata Thunb leaf provides a new theoretical basis.

“…[1] Quercus leaves are often considered a forestry waste except that a small portion of them are processed as a seasonal food packaging material exported to Japan, South Korea, and other places. [2] Quercus leaves contain flavonoids, such as rutin and quercetin, [3] which have medicinal values and can also be used as functional food additives, such as natural antioxidants and natural pigments. [4] Various methods can be used to extract flavonoids present in Quercus leaves.…”
