【摘要】 瑞香狼毒是我国北方草原上典型的多年生草本毒植物,资源化利用是新的治理思想和方式。以青海湖南岸的狼毒为研究对象,对其根部原料特征、化学成分和中柱部分制备糠醛进行了测定分析。结果表明:狼毒根皮层厚度与其最大直径呈直线关系;含水量为4.5%时,狼毒根中柱密度(0.72 g/cm~3)略高于皮层密度(0.69 g/cm~3);狼毒根中柱与皮层的化学成分有较大差异。由于狼毒根中柱部分聚戊糖含量较高,适合作为制备糠醛的原料,本研究中糠醛的得率为8.2%,与目前工业常用的原料蔗渣相仿。研究结果可为狼毒资源化提供参考依据。更多还原

【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/cm~3) was slightly higher than that of the cortex( 0.69 g/cm~3). 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.更多还原
