Summary
Low-temperature plasma extraction significantly boosts polysaccharide yield from Siegesbeckia orientalis L. This optimized method enhances extraction efficiency for natural polysaccharides, offering potential industrial applications.
Area of Science:
- Plant biochemistry
- Extraction technologies
- Natural product chemistry
Background:
- Natural polysaccharides from Siegesbeckia orientalis L. show potential bioactivities.
- Conventional extraction methods may limit polysaccharide yield and efficiency.
Purpose of the Study:
- To optimize low-temperature plasma-assisted extraction for Siegesbeckia orientalis L. polysaccharides.
- To characterize the purified polysaccharide fraction (SIE-III).
Main Methods:
- Single-factor experiments and response surface methodology for optimization.
- Low-temperature plasma treatment for extraction.
- Column chromatography for purification.
- Spectroscopic and analytical techniques for structural characterization.
Main Results:
- Optimal plasma parameters (80 kV, 153 Hz, 109 s) yielded 15.68% polysaccharides, exceeding hot water extraction.
- Plasma treatment improved raw material surface structure for better polysaccharide release.
- Purified SIE-III fraction (20.831 kDa) was rich in galactose, rhamnose, arabinose, and galacturonic acid.
- Structural analysis revealed rhamnogalacturonan-I domains, a triple-helix conformation, and specific glycosidic linkages.
Conclusions:
- Low-temperature plasma-assisted extraction is an effective method for enhancing polysaccharide yield from Siegesbeckia orientalis L.
- The characterized polysaccharide SIE-III possesses structural features suggesting potential applications in food and other industries.
