Bioenergy and bioactive components in leaves of Toona sinensis

ABSTRACT
Toona sinensis is an important tree for urban greening construction. T. sinensis sprouts are widely used because of their high medicinal and edible value. However, the functions and effective components of mature T. sinensis leaves have not been fully exploited and utilized. In order to explore the value of T. sinensis leaves in bioactive and bioenergy utilization, T. sinensis leaves were extracted with benzene and ethanol, and then the components in extracts were analyzed by FT-IR and GC-MS. The results showed that benzene and ethanol extracts from T. sinensis leaves mainly contained phenols, hydrocarbons, esters, alcohols, acids and other bioactive components. These bioactive components can be used in the fields of bioenergy, biomedicine, chemical row materials, food additives and spices. Among them, the content of bioactive components from benzene extract was higher than that from ethanol extract. These findings indicate that T. sinensis leaves contain a large number of bioactive components which can be used in bioenergy and other fields, and have broad prospects for development.
