Abstract An attempt has been made to account quantitatively for the main groups of chemical compounds in the dry matter of grasses. This was done by successive extractions with ethanol‐benzene, warm water and ammonium oxalate solution, followed by digestion with pepsin and a delignifying treatment to isolate a holocellulose fraction. The polysaccharides in the holocellulose were determined. It was found possible to account for 97–98% of the grass dry matter and to identify all but 1–3% of it. The use to which such detailed knowledge can be put to provide a better assessment of the feeding value of grass is discussed.
