| 摘 要： | 以料液比、微波时间、微波功率为考察因素,采用微波法正交试验优化,得出锦绣杜鹃叶多糖最佳提取工艺条件为：料液比为1∶20,微波时间60s,微波功率为160 mA.应用优化的工艺条件进行试验,获得了杜鹃多糖得率为22.578％.同时对锦绣杜鹃叶多糖年动态变化进行研究,结果表明在一年的不同月份生长期内,锦绣杜鹃在6～10月份多糖含量积量较高,而12～2月份多糖含量则为全年最低水平,可进一步为杜鹃多糖的开发应用提供参考.

| Abstract: | The research used the orthogonal methodology by microwave-assisted to optimized. The fac- tors include ratio of raw material to liquid, time of extraction, microwave power. The results showed that the optimum conditions of extraction were obtained as follows： the ratio raw of material to liquid 1 ： 20, time of extraction 60s, microwave power 160mA. The polysaccharides yield from Rhododendron pulchrum Sweet reached up to 22. 578% under these optimized conditions. The content of polysaccha- rides changed at different growing stages. The polysaccharides yield maintained a higher level in 6 - 10 months and a lower level in 12 - 2 months. The experiments provides the reference for the development and application of the polysaccharides from Rhododendron pulchrum Sweet. |
