In addition to supplying a large amount of timber to the country each year, there are still a large number of branches and leaves available for use. Some researchers at home and abroad have carried out a lot of work on the chemical components and physiologically active substances of eucalyptus and identified various chemical components such as terpenoids, volatile oils, hydrocarbons, flavonoids, amino acids and organic acids. The Chinese people also use eucalyptus leaves. Prevention and treatment, it was found that it has a good therapeutic effect on certain diseases. Eucalyptus rich in plant resources, research and development of this resource will help increase its
