Study on the Composition and Structure of Taraxacum koksaghyz Rubber from Different Origins
Hevea brasiliensis is widely used in societal production and daily life due to its excellent physical and mechanical properties. Despite its high demand and broad applications
it still faces limitations such as restricted cultivation areas
susceptibility to pests and diseases
and high costs.
Taraxacum koksaghyz
rubber
being one of the most promising rubber-producing plants
holds significant potential for optimizing cultivation and application through the study of its composition and structure from different growing regions. In this study
solvent extraction and enzymatic hydrolysis were employed to extract
Taraxacum koksaghyz
rubber
analyzing its impurity content
nitrogen content
ash content
gel content
plasticity initial value
and plasticity retention index. Fourier-transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectroscopy were used to characterize the structure of both Hevea brasiliensis rubber and
Taraxacum koksaghyz
rubber. Re
sults showed that for solvent-extracted rubber
Taraxacum koksaghyz
rubber from Xinjiang had higher impurity and ash content but lower nitrogen content
gel content
plasticity initial value
and plasticity retention index
compared to those from Inner Mongolia. For enzymatically hydrolyzed rubber
Taraxacum koksaghyz
rubber from Xinjiang had higher ash content but lower impurity content
nitrogen content
gel content
plasticity initial value
and plasticity retention index
compared to those from Inner Mongolia. The molecular weight of
Taraxacum koksaghyz
rubber from different origins
extracted by the same method
was similar
exceeding one million. The structure of
Taraxacum koksaghyz
rubber from different methods and origins was identical to that of natural rubber
