The original synthetic route of Bosein is: a large amount of xylose (Xylose) extracted from beech as the main raw material, and acetylacetone (Acetylacetone) in an alkaline aqueous solution to undergo Knoevenagel condensation reaction (that is, a compound with active methylene groups). (such as malonate, β-ketoester, cyanoacetate, nitroacetate, etc.) under the catalysis of ammonia, amine or its carboxylate, it undergoes aldol condensation with aldehyde and ketone, and dehydration And obtain α, β-unsaturated compound reaction), generate 1-C-(beta-D-xylopyranosyl)-acetone. After that, it undergoes a reduction reaction with sodium borohydride to reduce the ketone carbonyl group in the product to obtain 1-C-(beta-D-xylopyranosyl)-2-hydroxy-propane, that is, Boseine ( Pro-xylane).
It is a xylose derivative with anti-aging actives, which can promote the synthesis of collagen, make the skin stronger and more elastic, improve the fine lines of the neck, and prevent aging.
Pro-xylane is a mixture of glycoproteins derived from xylose.
Since xylose is abundantly present in beech trees, it has the ability to promote the production of glycosaminoglycans, namely glycosaminoglycans (GAGs).
As Pro-xylane extracted from beech trees, its effect is similar to that of xylose.
