Abstract: Clerodendrum trichotomum Thumb. is a kind of multi- purpose woody plant which grows quickly and has well-adapted ability. In order to discuss the feasibility of being biomass raw materials, caloric value and ash content in 1 year branch of 12 different provenances C. trichotomum Thumb. were measured respectively by the oxygen bomb combustion analyzer and method for determination of ash. The caloric value of 12 different provenances C. trichotomum Thumb.’s was evaluated. The results would provide a foundation for selecting excellent clone. The results proved that the average calorific value of the 12 different provenances was 15.25 kJ/g which did not vary much from the annual branches of the poplar (Populus×euramericana‘Neva’, I-107) whose calorific value was 15.34 kJ/g, but was lower than that of the Robinia pseudoacacia (18.45 kJ/g). The calorific-value’s discrepancy between 12 provenances was large and its variation amplitude was 3%. It showed that C. trichotomum Thumb. could be selected as biomass energy as the branches contained little ash.
