Abstract
Phospholipids of three kinds of muscles, viz., masseter, longissimus dorsi and biceps femoris muscles of swine, sheep, lean and fattened cattle were determined by the DAWSON'S method using Toyo No. 51A filter paper.
The results obtained were as follows;
1) The Toyo No. 51 A filter paper could be applied to the DAWSON'S method without preliminary treatment with acetic acid.
2) In each muscle, the content of total phospholipids had no relation to that of total lipids at all and each muscle seemed to contain a necessary amount of total phospholipids to perform its physiological function. Sheep muscle and M. masseter contained total phospholipids in the largest amount among the species and parts tested, respectively.
3) The composition of phospholipids in sheep muscle was different from that in the muscles of the other species. In the same species, the composition of phospholipids of M. masseter was different from those of the other parts. There were some differences between the composition of fattenned cattle and that of lean one in the content of almost all the phospholipid constituents, especially of plasmalogen.
