文摘
- •
Eucommia was successively fractionated by a multi-step treatment process.
- •
The extractum, polysaccharides, and guttapercha can be produced from the process.
- •
The extractum is rich in various bioactive components (mainly phenylpropanoids).
- •
The molecular characteristic of the polysaccharides fraction was elucidated.
- •
The guttapercha from barks had high molecular weights with a narrow polydispersity.
