| 摘 要： | 采用扫描电镜、水溶性糖含量检测、紫外光谱、红外光谱等分析方法,系统研究了不同剂量~(60)Co辐照处理对茯苓多糖的降解效应。结果表明,茯苓经辐照后,微观结构上颗粒变小、形状不规则,1000kGy和1200kGy处理出现平整切口;随着辐照剂量的增大,水溶性总糖、水溶性茯苓多糖增加,且1000kGy效应最显著;紫外光谱检测结果显示,1000kGy和1200kGy辐照处理有羰基生成;红外检测结果显示,800、1000、1200kGy辐照处理后羰基均明显增加,且1000kGy和1200kGy处理间的差异不明显;说明辐照茯苓后,茯苓多糖可有效裂解为以羰基类化合物为主且相对分子质量较小的物质,并呈剂量关系。

| Abstract: | The degradation effects of pachymaran by ~(60)Co irradiation with different doses were systematically studied through scanning electron microscopy,test of content of water-soluble glucose,UV spectra and infrared spectra.The results indicated that particles of the materials became smaller and formed irregularly after ~(60)Co irradiation,and several smooth cuts appeared after 1 000 kGy and 1 200 kGy treatments.The contents of total water-soluble glucose and water-soluble pachymaran increased with the increase... |
