| Abstract: | Analysis of first- and second-cutting alfalfa (above-ground portion of the plant, leaves, stems, and flower heads) and alfalfa holocellulose is reported. Appreciable differences were found between the chemical composition of the first and second cuttings of alfalfa.The solubility of the hemicelluloses of alfalfa and alfalfa holocellulose in various concentrations of potassium hydroxide was determined.A nonreducing sugar was isolated from alfalfa and identified as sucrose.Pectic substances present in alfalfa were isolated and characterized. X-ray diffraction data are given. |
