概要:
In this letter, we report the method of extraction of rubbery material from stem of Ficus microcarpa L. f. produced latex. The rubber component was extracted by using an ionic liquid as a solvent. The obtained rubber component was 1.7%. It is considerably less compared to 30-40 % of latex contained in Hevea brasilliensis. Natural rubber consists of cis-1,4-polyisoprene. The F. microcarpa rubber was suggested to be closely similar to cis-1,4-polyisoprene by comparison of its H^1 and C^<13>-NMR and infrared absorption spectra with those of authentic 97% cis-1,4-polyisoprene. On the TG curve, a mass loss of 96.8 % was observed around 381 ℃. These analysis results indicate that the rubber component of F. microcarpa consists of cis-1,4-polyisoprene. 続きを見る
