Eiffel Biotech continues to invest in talents. Our employee Patrick Wang’s article was published in Foods on June 11, 2021. The content is about Purification, Characterization, and Self-Assembly of the Polysaccharide from Allium schoenoprasum. The 2020 impact factor of Foods MDPI is 4.092. We look forward to our team’s further success. Our professional background is worthy of your trust! Here’s the link of the article

 

What Allium schoenoprasum is?

Allium schoenoprasum is a world-wide common vegetable while only its leave is used in the food factory. Its stalk is largely discarded, for potential heavy metal accumulations, which eventually lead to an environmental contamination. To fully utilize this vegetable and minimize its metal content, the major polysaccharide content is puried and characterized with chemical and computational approaches.

Graphical Abstract of Allium schoenoprasum purification and experiment

The major polysaccharide component from the stalk of Allium schoenoprasum (AssP) was extracted and purified. Gel filtration chromatography purified AssP exhibited a molecular weight of around 1.7 kDa, which was verified by MALDI-ToF-MS. The monosaccharide analysis revealed its composition as rhamnose: arabinose: galactose: glucose: mannose: fructose with a molar ratio of 0.03:2.46:3.71:3.35:1.00:9.93, respectively. The Congo-red assay indicated that there was no tertiary structure of this polysaccharide, however, it self-assembled into a homogenous nanoparticle with a diameter of ~600 nm as revealed by the dynamic light scattering measurement.

 

The solution behavior of this polysaccharide was simulated. The association of this polysaccharide was both time dependent and concentration dependent. AssP forms spherical particles spontaneously as time passes by, and when the AssP concentration increased, the spherical particles increased their sizes and eventually merged into cylindrical micelles. The diversity of AssP hydrodynamic behavior endowed potential versatility in its future applications.

 

The usage and future development of Allium schoenoprasum

Allium schoenoprasum is a natural extract like nattokinase. At present, it has obvious function of lowering blood lipids in rats. Eiffel Biotech is also actively studying the possibility of its collaboration with Nattokinase. To develop new raw materials for health care products.
