RESUMO
Cinnamomum camphora is an excellent tree species for construction of forest construction of Henan Province, China. The diverse bioactive components of nano-catalyzed pyrolyzates form cold-acclimated C. camphora branch (CCB) in North China were explored. The raw powder of CCB treated with nano-catalyst (Ag, NiO, 1/2Agâ¯+â¯1/2NiO) were pyrolyzed at two temperatures (550⯰C and 700⯰C), respectively. The main pyrolyzates are bioactive components of bioenergy, biomedicines, food additive, spices, cosmetics and chemical, whose total relative contents at 550⯰C pyrolyzates are higher than those at 700⯰C pyrolyzates. There are abundant components of spices and biomedicine at 550⯰C pyrolyzates, while more spices and food additive at 700⯰C pyrolyzates. At 550⯰C, the content of biomedicine components reaches the highest by 1/2Agâ¯+â¯1/2NiO nanocatalysis, while the contents of spices and food additive components reach the highest by NiO nanocatalysis. At 700⯰C, the content of bioenergy components reaches the highest by 1/2Agâ¯+â¯1/2NiO nanocatalysis, and the content of cosmetics components reaches the highest by Ag nanocatalysis. The findings suggested that the branch of the cold-acclimated C. camphora have the potential to develop into valued-added products of bioenergy, biomedicine, cosmetics, spices and food additive by nanocatalysis.
