Summary
This study isolated and characterized polysaccharide fractions from Tanacetum vulgare L. The main fraction, tanacetan TVF, was identified as a pectic polysaccharide rich in D-galacturonic acid.
Area of Science:
- Plant biochemistry
- Carbohydrate chemistry
- Phytochemistry
Context:
- Tanacetum vulgare L. (Tansy) is a plant found in the European North of Russia.
- Polysaccharides are complex carbohydrates with diverse biological roles.
- Pectic polysaccharides are a major component of plant cell walls.
Purpose:
- To isolate and characterize polysaccharide fractions from different parts of Tanacetum vulgare L.
- To determine the sugar composition and structural features of the isolated polysaccharides.
- To identify the type of polysaccharide present in the floscules (tanacetan TVF).
Summary:
- Polysaccharide fractions, tanacetans TVF, TVS, and TVR, were extracted from floscules, sprouts, and roots of Tanacetum vulgare L.
- Tanacetan TVF, from floscules, is primarily composed of D-galacturonic acid (61.4%), arabinose (14.7%), and galactose (10.2%).
- Structural analysis, including partial hydrolysis and NMR spectroscopy, confirmed tanacetan TVF as a pectic polysaccharide, specifically an alpha-1,4-D-galacturonan with arabinose and galactose side chains.
Impact:
- Provides detailed chemical characterization of polysaccharides from Tanacetum vulgare L.
- Contributes to the understanding of plant cell wall composition and polysaccharide diversity.
- Identifies a specific pectic polysaccharide with potential applications in food, pharmaceutical, or material science.
