Methods Dendrobium devonianum Paxt. from 6 townships in Longling were collected in September and December, and extracted by means of boiling water bath. Water extract content was determined by drying and weighing, and crude fiber content was determined by acid and alkali boiling, drying, and ashing. Results Water extract content were 36.50%~46.00% in September and 44.60%~52.35% in December, and crude fibre content were 12.35%~16.01% in September and 14.99%~17.10% in December. The difference of water extract content of different regions was 1.80%~10.7%, and crude fibre content of different regions was 1.09%~2.64%. Conclusion The contents of water extract and crude fibre of Dendrobium devonianum Paxt. are higher in December than those in September. It can provide scientific basis for determination of suitable harvesting time and comprehensive utilization of dendrobium resources.
