Study on the Dynamic Change of the Content and Molecular Weight and Molecular Weight Distribution of the Gutta-Percha in Organs of Eucommia Ulmoides Oliv
In this paper, We respectively study the Gutta-percha in the Eucommia's pericarp, annual bark and leaf, and systematically analyze it’s dynamic change of the content, molecular weight and molecular weight distribution, hoping that it could provide a theoretical basis for comprehensive development and utilization of Eucommia ulmoides Olive.. The results are as follows:
From May to October, the content of gum in the Eucommia's pericarp is significantly different (P<0.01) and increases gradually....
