摘要/Abstract

摘要： 为了缓解生产中天然橡胶来源单一的局限，本研究在前期筛选出的蒙古高原上能产生天然橡胶植物中，以鹅绒藤（Cynanchum chinense R.Br）为材料，通过有机溶剂萃取植物中聚合物，采用裂解气质联用法对聚合物进行定性及其组分分析，并用溴化液法对含有聚异戊二烯的萃取物进行橡胶烃含量测定。结果显示：鹅绒藤的聚合物中共分离出38种成分，主要有亚油酸乙酯、正二十八烷、正四十四烷及羽扇豆醇等。鹅绒藤的主体成分为聚异戊二烯，橡胶烃含量平均为11.73%，橡胶含量较高且生物量较大，因此，鹅绒藤可作为候选橡胶提取材料。

Abstract: To alleviate the single limitation of the natural rubber source in production,we initiated our studies by determining the potential alternative ability of Cynanchum chinense R.Br which come from Mongolian plateau.The rubber was extracted from the aerial parts of plant with organic solvent,and the chemical constituents were qualitatived by Pyrolysis gas chromatography-mass spectrometry.Thirty-eight compounds were obtained from Cynanchum chinense and elucidated as rubber,linoleic acid ethyl ester,twenty-eight alkanes,forty-four alkanes,lupeol,and so on.The rubber was further quantified by Bromide solution method,and the result showed a higher rubber content in the aerial parts of Cynanchum chinense with average 11.73%.

Key words: cynanchum chinense R.Br, natural rubber, organic solvent extraction, polyisoprene
