[Objective] The aim was to study on the biological yields of different parts of Curcuma phaeocaulis Val. and to carry out preliminary study on different resource quality characteristics, so as to provide scientific basis for the development and utilization of its stems and leaves resources. [Method] Representative plants of Curcuma spp. in main producing region were selected randomly and the different parts of plants were taken as the tested materials. According to the methods in 2005 Chinese Pharmacopoeia, plant yields and quality characteristics of C. phaeocaulis were detected. [Result] Yield of Ermujiang per hole reached 224.44 g; photosynthates in stems and leaves, fat-soluble ingredients, protein yields accounted for 40.61%, 42.05% and 38.06% of the total resources, respectively. The content of fat-soluble ingredients in leaves was the highest (2.897%). The total ash content and acid-insoluble ash content in C. phaeocaulis met the demand for RHIZOMA CURCUMAE and Curcuma spp. in the 2005 Chinese Pharmacopoeia. [Conclusion] Stems and leaves of Curcuma phaeocaulis Val. were available and valuable resources. Therefore, C. phaeocaulis in main production area should be harvested before wilting; and the stems and leaves of C. phaeocaulis should be reutilized to enhance its oil yield, or be used as feedstuff, which could further enhance the economic benefit of peasant households.
