Abstract: Stellera chamaejasme is a typical perennial herbaceous plant on the grassland in northern China and its resource utilization is a new way of thinking and management. This paper investigated the characteristics, chemical composition and furfural preparation from the central cylinder of S. chamaejasme roots in the south bank of Qinghai lake. The results showed that: The cortex thickness and its maximum diameter had a linear relationship. When the water content was 4.5%, the density of the central cylinder (0.72 g/cm3) was slightly higher than that of the cortex (0.69 g/cm3). There were great differences in the chemical constituents between the central cylinder and cortex of S. chamaejasme roots. Due to the high content of pentosan in the central cylinder, it might be suitable as the raw material for preparing furfural. The yield of furfural prepared by the experiment was 8.2%, which was similar to that of bagasse the commonly used raw material. The results could provide a reference for the comprehensive utilization of Stellera chamaejasme.
