The chemical composition of aqueous extracts of coniferous needles
- 24 Downloads
1. The group compositions of aqueous extracts of pine and spruce needles have been established. In their chemical compositions the extracts are similar to one another.
2. The individual composition of the monosaccharides have been determined. They contain glucose, mannose, galactose, xylose, and arabinose.
3. The component compositions of the vitamins have been studied. Ascorbic acid and vitamins of the B group have been found such as inositol, biotin, nicotinic and pantothenic acids, and vitamins B1 and B6.
